Description

I attempted these two earlier this year and ran into the reflection issue with my F/3 reducer that I ended up dumping the data. I have since fixed the reflection and decided to go after this again this time.

It almost brought back memories as I shot some L and RGB when the moon was out. Plus the mount was lost on a night due to a cable snag and I had to reshoot R again to finish this image. When I found out I was asking myself, 'you have one cable coming up to the scope where the Eagle was and you could not test that properly?', haha. 

Hope you like this result. Clear skies!
