Description

This is the first light of this setup! I had a lot of help from my AP friends to get me going. In all the testing and learning, I ended up collecting over 30h hours on this target. 

I was going back and forth on the 0.7x reducer and found guiding was not discouraging at 2800mm. I will shoot at f/10 for now.

Hope you like this result. Clear skies!
