Rodd Posted April 21, 2022 Share Posted April 21, 2022 I finally got this data looking more natural. I really struggled with brightness ( over stretch), saturation (globular clusters just are not THAT colorful), and, well, a million things. It’s amazing how a very slight adjustment can so greatly effect the image. If I want improvement, I will have to collect more and better data. c11ddge asi 1600. 4 hours of RGB using 20 sec unguided subs. (I now use an OAG) 22 Link to comment Share on other sites More sharing options...

tooth_dr Posted April 21, 2022 Share Posted April 21, 2022 Very nice Rodd. I just switched over to a larger scope and was going to shoot m13 but my spacing is off. I think you’ve done a brilliant job here. Link to comment Share on other sites More sharing options...
Fegato Posted April 21, 2022 Share Posted April 21, 2022 Yes that's very good. I don't even attempt GCs, but I suppose I should have another go and see if I can improve over one or two early attempts. Somehow, stars always seem to be a problem for me, so shooting loads of them and nothing else hasn't appealed!... 1 Link to comment Share on other sites More sharing options...

Stars are my weakest element. I think the key is not exceeding the full well capacity and being conservative with the stretch 1 Link to comment Share on other sites More sharing options...
assouptro Posted April 21, 2022 Share Posted April 21, 2022 Lovely rendition of a difficult object Rodd I keep coming back to this year after year as it was the first DSO I saw through my first “serious” telescope and I will never forget that feeling of excitement and awe! I like the star shapes, and the colours and your control of the core Its better than my last attempt thanks for sharing Bryan Link to comment Share on other sites More sharing options...

I can imagine what this target looks like in a big scope from a dark sight. Link to comment Share on other sites More sharing options...
ollypenrice Posted April 22, 2022 Share Posted April 22, 2022 (edited) These targets are absolute murder: at the eyepiece they glitter, in images they rarely do. This is a good rendition, for sure. If I were processing this I'd try one last thing, a bit of sharpening, more pronounced in the core and dropping off to nothing by the edge of the cluster. I wouldn't normally sharpen stars but, in this case, it would be a matter more of adding contrast to the core than of sharpening it. Sharpening is simply a small scale boosting of contrast, after all. Is this your full FOV? I think globulars benefit from a bit of dark sky context to make them pop.

I liken it to a 3D animation, and I have never seen that in an image. Link to comment Share on other sites More sharing options...

Interesting idea with the sharpening. I’ll give that a go. The core is the trickiest part, to remove the glare so individual stars are visible without losing a “globe like” look. As far as the FOV, alas, this is it. This was initially intended as a core image-like images of Omega Centauri that completely fill the FOV. But my focal length wasn’t quite long enough for that. I am finding that I am not wholly satisfied with any focal length yet, which is in marked contrast to something I believe, that they are all great! 1 Link to comment Share on other sites More sharing options...

Great Idea Olly--I didn't go crazy with it--maybe less than you had envisioned, but it is noticiable (if you squint) 3 Link to comment Share on other sites More sharing options...
