Far from good seeing but at last its kind of¬†recognisable - to me anywayūüôā

This is a stack of the best 25% frames from 20000 taken using my ASI 290MC tonight.

The moon was very nearby but I don't get many nights without clouds so thought I would still give it a go.

I left the scope outside for 6 hours before taking this to make sure the temperature had stabilised and that definitely helps.

Also reduced the gain on the ASI 290MC

This is with the 2x Barlow so about 4700mm Gain 159 exp 3.4ms

Nice images! Have to say I like the one without the barlow even more.

Clear Skies!

Thank you for posting this, I wanted to compare my sketch with someone's image from last night.  Obviously my view would be inverted left-to-right and top-to-bottom, I can pretty much see the same features.
