M27 photographed with Canon 60da, 12 exposures stacked

Tim Campbell let us use his 60da Canon EOS to photograph the dumbbell nebula.

Tim Campbell, Tim Dey and I were at the observatory while these images were taken through the c14, using Backyard EOS.

We took 12 four minute exposures, and 8 dark frames to reduce camera noise while processing the photos.

I quickly stacked and processed these using deep sky stacker, a free PC utility and photoshop.

I used only two curves when color processing the images in photoshop where most good image processors would spend more time and use more curves. I also didn't strip out and process the stars separately.

The image was also adjusted a bit on the iPad using Filterstorm, changing the exposure a bit and sharpening up the image a bit.
