Met with Harold and we were out there for three hours or more. We looked at the sun and did some test photos and frame grabs using the canon camera and the Stellacam.
I can't pit an image here at this time but I will later in another post.
We found the very high magnification of hr Stellacam on the c14 with the hydrogen alpha showed a lot of dust specs on in the optical path.
We turned the filter, Renee the t-filter adapter, changes and rotated the diagonal and the camera, the dust specs remained. In place. It wasn't dust on the surface as the offset 4 inch filter was rotated in a different position over the front of the telescope.
There must be dust on the internal surface of the primary or secondary surface. Considering we were using about 800 power it's probably something we should expect to run into.
