Sidonio'd Eta Narrowband

[rat156]

Hi All,

When I asked for some comments on the last Eta Carina narrowband image, I got them. Fred said that I'd overblown it, and a few people mentioned that I'd clipped the blacks.

The black clipping was my settings in CCDStack, now remedied. The colours were also a bit garish, so I've toned them down (a little) and shifted them a bit.

During this process I discovered a nice piece of software for star removal (Straton), which I used to create the HST (False RGB) colour image. I had discovered my grey halos were from the colour part of the image (when the magenta colours are desaturated to remove the violet stars common in NB images). This has left me with predominantly white stars, but that can be fixed by taking some short RGB star images, which I've also worked out how to get back into the main image (hopefully).

Hope you all like the changes, more comments are welcome.

I like the colours, nice and sharp and a different framing....quite worthy of having my name associated I'd say old chap :confuse3: :P

Really like them both. The starless has a painterly feel - in a good way. Lovely.

Like the changes I do Stuart. Very sharp, and a less electrifying palette is easier to consume. Excellent work!
