Description

LRGB:5h+2h+2h+2h
This pic was taken from 2022 to 2023.
In December 20th I did it for 8 hours,2 hours of each channel.
Now after a month I took another 3 hours L before the sky filled with clouds.
The system worked pretty well,even it was frosting.
There's no cold weather for crazy astrophotographers.
