That's nice and sharp Roger good capture!
Thanks Mark
Roger
Nice sharp stars and plenty of H-alpha. The OIII looks fairly subdued for some reason.
13 hours! That's a long total exposure! Is that your longest so far for one image?
Mark
i think so and joined different sessions quite easily as well, thanks Mark,
Roger
Really nice data Roger. As Mark said. Possibly a bit more detail could be teased out and a bit of restraint in some parts of the processing could make this a really good picture.
Great shot Roger and nicely framed!
Roberto
Thanks Roberto,
Roger
Very nice Roger
Looks very clean and conrtasty; what happens if you leave a little more noise in the background?
