Description

Lens opened at f2 this time. Lot of signal but lot of vignetting too. I had forgotten the big difference of vignetting between f2 and f2.8... It was not completely corrected by the flats. I think the flats were not the best though. I will do better next time.

I also fighted several gradients. We can see remaining color casts.

Anyway it gives an idea of what could be done on this target. A dark site would help :-).

Version B shows a widefield version.
