Description

Abell 2218 gravitational arcs detection tentative

total 20h kept (80 frames of 15min over 100) using a 180mm refractor and the KAF8300

Taken during 5 nights. Only 3 where good enough for luminance frames.

What I conclude after this first trail. This kind of object requires very very good conditions to get (only) the begining of a result

- no moon

- very good seeing needed : 2.3" or beeter

- no light polution

- image only close to the meridian

- greatter diameter would be usefull

- tighter sampling (about 0.5" against 0.76" here) would be usefull

I am still trying with a biger telescope...
