Description

My first time imaging these emission nebulae. I also used the dither option on the ASIair for the first time (RA only with Skyguider Pro). Did not realize how much time a 1pixel dither between ever exposure would add. A 2 hour integration time ended up taking hours.

The single exposure frame did not seem like much and I was not very hopeful about the end result. I was amazed at the stack result! The biggest post processing I did was many levels of star reduction to really make the nebulosity pop.

I used a cannon 100-400 mm tele lens with my ASI183MC. I always have had focusing issues with this lens. I used a Bahtinov mask and it showed perfect focus on Polaris, but the final exposure stars are still not as tight as when I use the AT60ED refractor. My next session with it I will have to pay even more attention. It is probably very sensitive to the helical focuser.
