Description

This was an experiment with 1 second exposures using my goto dobsonian. I've seen others on astrobin (lowenthalm) get very good results with this approach and I wanted to try it. This one came out OK. Needs better processing. I need to get a coma corrector also with this setup as I had to crop a considerable amount of the image and you can still see signs of the coma.

I didn't debayer this image as there were just so many exposures to deal with. I may try increasing the exposure duration somewhat with the possibility of having to throw more away.
