Single sub, which is my best shot of M42 from Sunday nights session. Taken with my Nikon D90 and 400mm lens tracked with the SA.
Taken at Iso 800 F5.6 for 120s. Rough crops and edits in PS Camera Raw.
My intervalometer wasn't playing ball so only have a limited number of subs. Also Polar alignment was poor as my tripod is very wobbly, and the ball-head is not so great, so micro adjustments for framing was hard, (also knocking out the alignment every time)
Definitely, need to work on my focus and polar alignment but happy with the results. I'm going to try to stack the few frames that I did manage to get If I can figure out the processing.
