I've been wanting to get this for a couple of years. Various problems have kept me from imaging it. This year I got it! It is challanging to process due to its very low surface brightness. I imaged with the goal of bringing out the Ha regions of this very faint galaxy (thus the unusual filter combinations). I find it interesting to see the subtle bar across the middle of the galaxy! My aperture doesn't resolve the central stars like a big RC would but I think it turned out ok none the less.

That is a very faint galaxy. I dont think I've ever seen that before. Good show.

Wonderful image! Unusual ring pattern in one of the pinkish areas.

I have a question. When you say 60 minutes for one of the colours, was that one exposure or several added together?

Beautiful shot! There's a lot going on in and around this galaxy.

Just excellent Tom! The use of Ha light made for an unique perspective on this object. Very well done! I would submit this one to APOD.

Best,
