Here is an image I took over the weekend from my dark site.

After a super wild thunderstorm on Friday night I had 2 perfectly clear nights, if a bit windy on the first night. Seeing was good (7/10?).

This one was almost all night and is well placed after about 11-12pm for imaging.

TEC180mm with field flattener. FLI Microline 8300 at -35C (even though it was 22C ambient). Astronomik LRGB and Astrodon 5nm Ha filter (not S11 filter by mistake!!!).

HaLRGB 75 60 30 20 30 .

I think I will shoot some O111 on this one next trip as I'd like the gas loops to stand out more.

Greg.
