Not that it has been good weather…but I managed something. When this comes around again I will be ready to get much more of both Ha & OIII…with some RGB for the stars.
For now it will do…happy to have got it at all with a 4" scope.

Very nice! I’ve never attempted this. It looks like a very difficult target!

Thanks Jared. It is indeed a very dim object and in truth I did not have enough subs to make it anyway easy. I indeed found it difficult to get a final image…but at least I have a good head start for the next time it comes around.
