I took this image back in May, and never got to process it properly. I thought I could get more data for it but that didn't turn out to be the case, so here it is.
NGC 4945 taken from Mt Stromlo Observatory in Canberra.
That's a really nice image. Only detraction are the 2 large blue halos on those bright stars. Try sponge tool set to desaturate 50% and rub on the blue halo to tone it down, that would help.
George, that is an excellent image of NGC 4945, lovely processing and great colour. I don't mind the blue halos actually in this image, they actually add something for me, you may have issues with the Orion Nebula region or the Pleiades though.
I don't think more data would have added much any way

Greg.
Yeah I havn't been taking images for that long and this is probably the first time I've encountered large stars in the vicinity of the image. I'll try to fix that up.

Haha! It's unfortunate that most of the telescopes on the mountain were destroyed in the 03 fires, it's mostly an office space now for ANU's astronomers.
Also, does anyone know what the nebulous feature I've circled here is? It's in all of the images of this target, but I can't find it on my Cartes du Ciel program.
Very nice image George. If it were mine I would try to neutralise the background a bit more to remove the blue cast on the background.
Lovely image of a surprisingly hard galaxy. Well done.
The little circled object is another galaxy, NGC4976.

Thanks Wayne. Actually I think 4976 is a much larger galaxy out of the frame toward the top of the image. Heres the APOD with this field that includes 4976.
It also shows the feature I'm talking about, which looks more like a nebula than a galaxy methinks.

Cheers Doug, yes I noticed the blue hue and a bit of purple gradient after I posted the image. I'll fix that up sometime.

That said, you have done really good on this...star colours are great, and the galaxy is resolved well.

Hi Martin, thanks for the feedback. I'll try the sponge tool, if that doesn't work we'll see...
Really like the framing. It's good to see the galaxy hanging there in between those two blue stars. Puts everything into perspective and adds a bit of variety to the shot colorwise.
Yes it is 4945A. I was wrong about the nebulous part. It's interesting how it is hidden behind a star.
I've been playing with the image a bit, and have attempted to neutralise the colour gradient, and get rid of the blue halos. I'm not sure whether the image looks better without the halos, but I think I solved the gradient and the blue hue.
