Moon map pro view of banting crater area

It's interesting to see the detailed maps after reviewing what I saw and looking at moon atlas.

The Moonmap Pro software has more details and the imagery shows more streaks and more detail. Clearly showing me what I saw and what I could not.

Here's a sample screen shot from the program.

Combining the two programs provides some serious ability to view and identify lunar features in detail. Another reason to own an iPad.

A fun time surveying the moon throughout the binocular telescope

I took some audio notes to review.

Sitting in a chair with moon atlas running on the iPad. I selected a mare and started searching to match craters and other features.

I ended my viewing with a pair of 15mm eyepieces in the Vixen binocular telescope.

I could see the a b c d craters that correspond to the messier craters. The smallest of these being 1.6 miles across. It looked like a bright dot. You could tell it was a crater.

I could see more detail with my left eye. The right eye for example would not see the 1.6 mile crater but it would blink in and out. The right eye would confirm what the left was viewing and the small crater would pop in and out of 3d perception.

Here's a screen shot of the messier craters, from the moon atlas program. The streaks to the left really looked like a comet, with the messier craters appearing as the head of the comet. A fitting name for the craters.

For those of you wondering, just how good and how much detail a pair of binoculars that have 3 inches of glass for each eye can be, the detail I saw was better from a crater perspective than what is shown zoomed in fully with this program. There were a lot of craters and this with an almost full moon. However the ridges were less visible than with the Moon Atlas program. There were a lot more bright spots and you could see more bright ejection paths from crater impacts than this program will show on the map. The shading was more subtle than shown in the moon atlas. And this was under viewing conditions that were far from ideal. A larger telescope would show more information. One member of the FAAC club mentioned that the moon map programs seem to lack the contextual view (maybe they need a split screen mode) for the iphone or ipod touch. This may be a problem. I actually don't have a moon atlas loaded on my iPhone so I can't confirm that. I can say the iPad had a large enough screen to easily see the context of what you were looking at and zoom in to look at details and figure out what you were seeing. I could have spent 10 hours of moon watching with the Moon atlas sitting on my lap, but you have to stop and get some sleep. With bigger scopes you can see even more detail. The moon atlas at $6 seems to show a lot of detail, but naked eye astronomy through the telescope shows so much more detail, I found myself wondering if there was a way to have a more detailed linked map, something like the other moon mapping program that has a poor interface. That other moon mapping program called moonmap pro has a very unstandard and segmented interface.

MoonMap Pro is not as user friedly, but the satillite maps of the moon in great detail. It would be great if some kind of mapping software could combine the two. In reviewing this post and adding to it, I pulled up the MoonMap Pro software and looked at seciton 42 which contains high resolution sattillite imagery of some of the earlier areas I was looking at. I looks like you could use the Moon Atlas program on the iPad to get your bearings and figure out what section and detailed features you are looking at, then fire up the MoonMap Pro and start drilling down into sections to get a really close detailed view that is greater than you'd see in your small telescope. See my next post for a sample screen shot of the MoonMap Pro close up view.

In at the observatory but will likely be gone by 12

Just stopped by to look through my ninotelescope at the moon and use the observing chair.

And realized when I opened up I don't have the chair here tonight.

There is a lot of haze tonight

The observatory will not be open.

Went on an errand to walmart

Decided to buy a pair of polirizing sun glasses to check them out for lunar veiwing of the full moon.

They cut down on the light but are nowhere near the effectiveness of variable polirizing filters and they make it more difficult to view. Because of course your eyes are further from the eyepieces with them.

Test photo in parking lot below.

One thing about viewing the full moon, you can get away with being in a very light polluted parking lot.

There's a chance the observatory will be open tonight, but it may be closed until 11pm

There may be a problem with the goto star model and we may only allow FAAC members inside while we are setting up the model. The public is welcome to stop by, but we may be busy and not have a lot to show you, and you might only get a glimpse through some other small telescope or have to wait.

If your not a FAAC core member or FAAC member, feel free to stop by and check it out, but don't go out of your way to block off a large amount of time for tonight, because as you can tell there's a chance we will be pretty busy.

It can take an hour or two to get the mount setup. I'm not sure what happened to the star model but I have some ideas what might have messed it up. We need another star model in there anyway.

Sorry about the long and kind of conflicting post. My operating norm seems to be to show others the scope and the skies if things are worker fairly well. We haven't had a perfect model in the mount for some time and have had some issues with the star model in the goto controller in the past.

There is also a way to disengage the model and create a Tpoint model in the computer to have some separate star model.

One potential problem is in diagnosing another problem I moved the mount slightly manually, which is a mistake that can throw off the model.

What is a star model? It's basically a map of stars in relation to the telescope mount setup. It maps the stars and tells the computer chips inside the goto controller where the mount is pointing in relation to the stars in the sky. The goto controller has things like a clock and gps position set inside it. Using some clever math and programming, the mounts goto controller should know where it is pointing and be able to point the telescope to a star and object map to one of many thousands of objects in the sky.

Some computerized mounts with small telescopes you can buy like a Celestron Nexstar series of telescope or some Meade models of telescopes have a goto mount. A goto mount can tell the mount where to move automatically and often will control motors in the mount to cause the mount to move and point at an object the user selects. There are dozens of configurations of goto type mounts and also other various types of computerized setups. Some mounts have a something called digital setting circles, which read the position of the mounts shafts as they rotate. Giving a feedback as to where the scope is pointing. Most goto mounts just memorize where you pointed the scope because you told it what the telescope is pointing to. And these will control the motors and know how far a motor should turn to move from one position to another. So the goto controller will tell the motor where to point. But it will not receive feedback from the mount unless it has digital setting circles. This means most goto mounts are using guesswork as to where the mount starts pointing. And as long as the mount isn't moved manually, it stays pointing where the computer last thought it would be pointing. But if you move the telescope, the mount doesn't report where the telescope moved to, because it didn't use the motors to move it, but instead you used your hands to move the scope. So the scope moves, but the computer goto controller doesn't know it's moved. It has no sensor to realize the mount has moved. So the start model is OFF.

There can be other problems as well. There may be some kind of error or power glitch that may throw off the model. In theory a power glitch should not throw off a model but this may be one of the things that has been happening at the observatory as well.

Here's a shot from a few weeks ago : the ring nebula

Here's a wide field shot. This was shot at the observatory using my canon t1i on the Meade 80mm refractor. This is mounted with a t ring adapter on the Meade and of course the mount allows tracking for this long exposure.

I'll have to look up the length of the exposure and other data from the metadata on the image. It maybe something like 30 seconds at iso 800 or something near to that if I can recall correctly. I'll check and repost.

The ring looks almost like this size wise with a low powered eyepiece like the 40mm through a wide field scope like Seans 10 inch rich field Orion telescope or something like the 10 inch Newtonian I use which is a f5.35. Both being rich field scopes.

This of course is a much smaller telescope but the long exposure makes up for the smaller size objective.

You may have to click on the following to load the larger sized image.

Quick update

I still went by the observatory late this afternoon. I wanted to air out the observatory and as the clouds were threatening but there were some openings on the clouds. I decided to try to get a quick look at the sun using the Lunt Solar Scope.

Warning: I cant forget to mention in each post about solar viewing, only use a special telescope or filter designed to safely view the sun. Don't look at the sun without using proven safe solar viewing equipment.

The sun was amazing in the hydrogen alpha solar scope. I wish I could have taken some photos but I ran out of time and the iPhone is just terrible at taking photos through the solar telescope.

There were many large prominence/flares flying off the sun. I've never seen that much large flare activity up to this point. Four very active flares. I've only been observing the sun with this type of scope for six months or so. The sun is very active today. There was a large sunspot group as well that Nasa mentioned on their website. And some dark lines as well which were loops of solar flares blasting off the surface, but not visible near the edge of the solar disk. These loops look like sharp black lines on the disk with hydrogen alpha viewing. A lot of activity and I wish the weather would have allowed the observatory to show this to visitors today.

Soon the clouds covered the sun and I was on my way to other errands. The sun peeked a bit through the clouds. I took a quick snapshot with the iPhone while at a stop light. This is through my windshield so it's not the best quality but you can get an idea how nice the sunset was from Lincoln Park.

Solar viewing cancelled for Saturday

Sorry about that last post clouds look really bad and are moving in.

Don't stop by because the view will not be worth the trouble.

I should have consulted the clear sky chart before posting.

Another shot


Here is a shot with just Sean and I looking through the telescopes when no visitors were present.

Grosse Ile Michigan




- Posted using BlogPress from my iPhone

Photograph from the Island outing.

The Wild coyotes barking in the distance, Venus, Saturn, m13, Ring nebula and Jupiter were our non-lunar targets that I can recall. We looked at the moon more than we probably should have considering conditions. We had fun overall at that's one of the main reasons to be in the hobby.

Here's is Sean and a couple of visitors looking through the telescopes. A few people he knew from work dropped by and observed briefly. The girls in this picture were enjoyable to talk with and provided some great comedy relief at times. About the only thing that would be distracting to an astronomy purist was an occasional flash from the camera the girls had with them. I didn't have time to research and show them how to do a time exposure on their camera. We really didn't have time to go into to many technical details.

The weather was awesome, a slight breeze, perfect temperatures and few bugs. Almost textbook weather you think about when you're young and wanting to stay out all night to just lie down on a blanket and summer camp looking at the stars or for meteors. We saw a few meteors and more than one satellite pass through the field of view of various telescopes.

The girls likely didn't see any satellites through an eyepiece, they looked at the targets rather quickly and then would make comments and joke around a bit with us.

All in all a fun time. The site had some lights that were a distraction for dark ground viewing. With the larger low powered Plossl eyepieces at times I would see reflections from ground lighting, not much you could do to combat that, perhaps setup with your car blocking some ground lights and adjust the height of your tripod. The vistas were amazing. A really nice low horizon, just what you'd want from a nice observing site. I wanted to try to get a shot of the Milky Way, but the moon was bright and in that area and I was running out of time as it set.

Driving back across the free bridge to Trenton, the moon hung brightly between the large chimneys of the local coal burning power plant. I wish I had my camera ready and had a shot of that.

Wasn't able to get back to the observatory last night

To distracted with the good viewing and chatter at Sean's observing location on the island last night.

We were there until 2am.

On a different note here's a photo of the cover of the dedication booklet naming the Hector J Robinson observatory.

The cover was printed on paper that had the shade of photographer blue. Photo blue would not show up in a scan as a color and wouldshow up as white. The original folders would not scan as blue if you tried to copy them.

It's possible that this fased or at least moder cameraslike the iPhone will record photo blue and not ignore the color.

In any event here it is. And as you can see the observatory was named after the school teacher in 1975, long after he retired. He came back and visited for the dedication we had for him. And altough it was built in 1964 it was not named until 1975 by the school board that was lobbied by the school club and likely the club sponsor at that time.

Note we didn't have a sidewalk and the dooris lower now since the floor was raised in 2009 thanks to the many volunteers and if course Toshiba.

I'd mention more detailsbut there is more on the FAAC webpage. Google FAAC aatronomy to find those links.

Here's the plan, I'm observing in grosse ile tonight, but I may stop by and open up for a short session around midnight

I know it's not much of a post. Depending on conditions and how things go and also how tired or energized I am, I may open up tonight at the Hector J Robinson observatory.

The conditions will be clear according to the clear sky chart and average transparency. The biggest problem is I'm very tired and may only be observing for a short time tonight. Usually I get energized with observing. The negatives for me observing today is the moon is almost full and I don't have moon filters or polarizing filters so I will be burning out my mint vision much of the time if I focus on the moon. I need to get two polarizing filters for the binocular telescope and forgot to get those for the moon. The moon is so fun to watch in the binocular telescope I could just use the little Vixen scope to just watch the moon and be extremely happy.

One of the hazards of observing during the week is the possibility of losing track of time and missing getting enough sleep. I lost a ton of sleep yesterday. But this was not due to astronomy, rather a sore back that kept waking me up.

I took a peek at Jupiter last night late after getting home, just briefly before the clouds obscured the view. I've been reading about really nice wide field eyepieces and thinking about the advantage they might provide for the binocular telescope. I'm not sure if I need to adjust the telescopes alignment a bit or not, there are settings to adjust it, it could have been eye fatigue. I'll see how it looks tonight.

I also watched a binocular telescope video DVD video by JMI and this video although a typical sales video seemed to be really compelling toward that type of visual experience. I don't know what I would do if I had a chance to look through one of those large binocular telescope monsters? It might not be healthy for ones bank account.

Morning sky conditions reflected off the outside of the telescope

I don't have a solar filter for my little telescope so there is no safe way to look at the sun with it.

How about a picture with the sky reflected off the round body of the little telescope?

Sample of hazy and cloud conditions

Looking at the moon, of course with this log exposure the moon looks really bright and is overexposed.




- Posted using BlogPress from my iPhone

Can you see part of the big dipper above the telescope?

Of course I'm in a blur effect with this self timer photo. As the photo is being exposed I'm taking a seat to look at the moon.

The photo was taken with a Canon t1i, 13second exposure, 800 iso setting.

I'm using the camera tripod for the binocular telescope. The camera is just sitting on a Celestron Nexstar tripod.

Last minute view at moon with binoscope

Woke up late and headed out to take a look at sky conditions. Conditions are marginal at or near horizon with some passing clouds. Like a bowl. Just looked at the moon and took a few shots of the binoscope by the observatory to get some kind of photographic record.

The moon at 36 power through the binoscope looks to flicker a bit almost like a tv image. Contrast and details are still amazing with two eyes. Really love this for lunar viewing. Now I'll have to pick up some moon filters for this. Later before I left I tried taking a quick look at the moon throughout my little Bushnell F4 4 inch telescope,using a 32mm eyepiece. The little bushnell gave an extremely wide field view at a much lower power. I could fit six moons inside the field of view, that is to say six moons across with the little F 4 rich field. The little scope had a wider field than the higher powered and narrow field Vixen binocular telescope. View thought the binocular telescope was of course much more pleasing.

Picture of binoscope and observatory at night to follow in later posts. Really nice light breeze and moist air, still humid and warm out but almost ideal except the sky isn't perfect but rather a semi hazy bowl. I didn't take any pictures of the rich field 4 bushnel telescope in action.

Sitting by the football field two kids yelled out of their cars as they drove by. Looks like some kids are out and enjoying the night cruising this evening.

No mosquitoes, but I stayed on the black top and sidewalk.

I'm leaving the school now to grab a late night snack. I probably won't return tonight becuse I had a long day and I'm ready to get some sleep after the food run.

There us a bright star less than a half a moon behind on the dark side. Probably was oculted/covered by the moon earlier. Very visible through the binoscope and the background looks jet black.

I was at George K's house observing via computer

Notes from last Saturday and Sunday morning:

The faac club had a few outings announced, one being at the novi sports park in Northville Mi.

Bit due to a variety of reasons I was the only one to show up at the sports park site. Clouds had threatened and many were bisy with other last minute projects. Trying to salvage some viewing and not waste the trip without some socialized star gazing I gave George a call. George was up but not observing however he mentioned he could be observing in about 2 minutes of I wanted to stop by.

Hours and hours later George was showing me his computer programs and imaging software we were surfing the net, he was imaging and showing me many images as we talked about just about any subject and maybe every subject about astronomy, it's all kind of a blur now.

I wondered at that time how many hours George could stay up? He was energized when on the subject of astronomy and maybe I could have been more energetic but I was out the night before at the lincoln park hector j Robinson observatory until 3 am.

I finally after most of the night made it back home, at about 5:50 am. Jupiter was brightly shining and a I felt re-energized from the drive back and decided to try out the binocular telescope in this planet.

I had so much fun I spent a what seemed to be as hours at the scope. But it was closer to being one hour. Maybe the rem sleep states approaching was changing my perception of time itself, or maybe it was just the view.

Finally
Daylight was taking hold and the sky was lit up still the scope shows great views of the planet.

Jupiter and the sun had risen, Jupiter was far away front the sun was a treat to look at while daylight had arrived. I was really happy to see the performance of the scope. It would be even better had I two sets of televue plossls instead of the set vixen provides with the scope.

The field of view in the binocular telescope is wide enough to easilly keep tracking an object even with a simple mount. A big plus for showing others.

As the sun rose thin clouds seemed to roll in more and more.

The clouds were thin and didn't affect my veiwing much the telescope seemed to look through the thin cloud layer that we had. The clouds were not very thickbut I was still surprised how well the scope performed in marginal conditions. It should be a real treat when looking at the moon.

I'm out at the Novi sports park tonight

Sorry the observatory won't be opened tonight, at least it won't be by me.

Sky conditions are party cloudy with thin clouds in some areas and only average transparency. Yesterday late the sky was much better.

I was driven out of the park by mosquitos, because I left my repellant at home.

Had to go to a store and take a break, getting repellant. Probably bite eight times and I was moving around trying to break down the scope and get out of there.

Photos may follow later if I get anything.

Went out and focused on Mars and Saturn only.

Mostly Saturn with my 10 inch Newtonian that I hauled along.

Saturn was low on the horizon and lights from the school likely added light artifacts to the image I was seeing.

The dome cut out all the outside light from the low lights and this gave a big advantage to the C 14.

I'd post more but I'm fairly brain dead at this time and need to get some sleep.

Shot of the big shootout below. Didn't have any visitors during the time I was there and this allowed me to take some time taking mostly night photographs. I tried to take some photos of Saturn with the camera on the 2 inch guide scope on the Big Newtonian but I ran out of time and didn't get any decent shots worth posting of Saturn.

Moon through the old blue tube with barely any coating

Let's see the last time I looked through this was in 1977., the year we built it.

This image is not anywhere near the quality it should be, had the telescope been stored properly from the old days. Perhaps much of the coating would have been gone anyway due to the cold winter temperatures in the observatory.

The view through this (and it's not even optically aligned as it should be) were better than in this photo.

Basically any telescope you would purchase, even a cheap store bought would give a better eyepiece view than the photo below.


- Posted using BlogPress from my iPhone

Photo of 1977 blue tube notice mirror coating is gone

I wrote a long post about this but closed my blogpress software before it posted and lost the post.

Rather than recreate it, I'll write more later.

Notice much of the coating is gone but the mirror and scope could be restored. I think it might be interesting to do a partial restore and fix up the optics a bit, simply recoating it and perhaps adding a different finder.

We will see what happens. We don't look thru this now. But I set it up to quickly look at the moon last week. I also took a photo of the moon with this last week. The photo of course wasn't very good, I'll post one of them later.

We had a great time at the observatory last night

Gary, Greg, Tim, Sharron and I had a great time at the observatory. Sharron was only there for a short time. The rest of us were there for a few hours. We didn't take to many photos and added the Canon into the mix near the end of the night. We took mostly photos on the Meade to confirm the object we were looking at.

Here's a wide field view of the ring nebula. This is a wide view from the little 80mm Meade refractor, so you'll need to click on the link and open up the big picture and zoom in to see it. I have bigger photos of this from the C14 and other nights. Most of my photos are just a shot with the Canon mounted on the telescope and I rarely use stacking or other higher level touch ups on most of the photos I take at the observatory. This just came from the camera.

We ended up doing more looking, winch is a good thing, especially when the skies are cooperating. So many conversations about astronomy were going on in the dome, it's impossible to recount them all. What a great time.

The weather was really nice out, with occasional fireworks fired off by the locals, but that didn't bother us.

One FAAC member told me he has driven by the observatory at least a dozen times and never saw me here. Maybe he just missed me, sometimes I get out later and I've been really busy and slammed during the week so I did skip some nice nights and didn't open up or put a post here. Also I have been opening up at times and just notifying the FAAC members on the board. And sometimes I decide to open up at the last minute and don't always post it here. If you drive by and see my car near the track near the observatory, or my f150 truck and this would be inside the fence near the observatory, then chances are I'm there for some event. Usually the small gate is open when the public is welcome which is almost eve time I'm out. The only exception would be for some special maintenance event, which is rare.

Conditions were nice last night, but it seems that the naught before had better seeing conditions. at least at the observatory. Conditions were still very nice, it seemed a bit better the night before.

I left around 3 am, hanging around a bit after the last visitor left.

We will be open tonight

There may be limited viewing opportunities for visitors at times while we adjust the mount. We usually can show visitors something through the telescope. I'll have another telescope handy, you may have to wait a while as we do some adjustments tonight.

We try to put a priority on viewing and showing the night sky when the viewing is good. Just be prepared if you visit tonight to possibly wait tonight if we are adjusting the mounts model.

I'll try to bring a big telescope align as backup but I'm not promising the big backup dope will be there.

No solar observing today however from my perspective because I have other things to do until nightfall.

(and unfortunately there is a lot of activity on the sun lately and kits a joy to view thru special telescopes like the solar telescope we have in the observatory.)

Warning, never observe the sun without a proper telescope filter setup. Ask me or a competent astronomer if your in doubt before attempting to look at the sun. Best bet is to be safe and not observe the sun.

Here is a picture of the moon from this morning. It's not a great photo but it gives a rough idea what can be seen at times. The view is actually much better looking through the eyepiece yourself. Also the moon rises late. You will not see it early in the evening and we ay not be out there late enough to see the moon tonight.




- Posted using BlogPress from my iPhone

I stayed up all night and was home and falling asleep at 6am

I finally tore myself away from the eyepiece. Jupiter was so wonderful to view under the clear transparent conditions. I basically couldn't walk away from the eyepiece.

Nobody else showed up but I may be out tonight at the observatory or take my telescope out somewhere else.

I also may be out at the observatory this afternoon to so some solar observing at 4pm. Check back here for more details or post a reply if your interested.

Click on full sized image below to get an idea what Jupiter looked like this morning through the eyepiece. It was so bright it looked like a full moon and was almost blinding in the eyepiece.

Also it had an covered 4 degree field of view inside the eyepiece, which means it appeared to be 8 times bigger than a full moon would look to the naked eye (observing the moon without a telescope) looking at the moon.
