Abell 56 not see often on the website

Recommended Posts

oh, another Abell pn..   this one looks very hard to capture at all, well done.

I'm wondering with these very faint nebula if a scaled red sequence could be subtracted to take out the foreground stars leaving the nebula more visible.

Yes, this one is very hard to capture and in OIII, it is more difficult but I will do later some shots with OIII to get the colour red and maybe the stars not too visible around it.
