My goal was to capture as much of the faint outer halo as possible. The stars appear as cyan due to the differing exposure lengths of H-a and O-III.

That's astonishingly good, possibly the best we've seen, certainly right up there. Wonderful.

Very good shot :thumbsup:
Is it close to "full frame" :question:

:thumbsup: Fantastic well done, hope I can manage something as half as good with my C11 edge :)

Really well done Adam! With some averted imagination it looks like you've closed the OIII loop! Would be interested to see if the OIII data alone shows the full 360º as that stuff is super faint.

Time well spent Adam - lovely image - well done! :thumbsup:
