Description

One hour before dark night stops the M20/M8 rises enough to take first lights.
The transparency was perfect, the seeing was so bad maybe 25 ".
I gave it a try.

I made a quick shot and processed super pixel (2x2 bining) for good S/N.
after the the time has gone for RGB (11x 5 min) I checked it by the histo
I started to make HA lights (4x5 minutes, the minimum to avoid dust by dithering)
