Rodd Posted April 23, 2022 Share Posted April 23, 2022 (edited) M109 is a huge galaxy--a trillion stars. It's hard to believe we can image something 83 million light years away in such poor conditions. This project took over 4 months--all of it frustrating. I wanted to add Ha, but didn't have the patience to wait another month. Not sure if M109 has appreciable Ha--I was not able to confirm this C11Edge HD with OAG, .7s reducer, and ASI 1600--bin3 Lum-423 30 sec, Red - 115 120 sec, Green - 120 120 sec, Blue - 116 120 sec Edited April 24, 2022 by Rodd 20 Link to comment Share on other sites More sharing options...
Rodd Posted April 24, 2022 Author Share Posted April 24, 2022 (edited) Photometric color calibration. I think I like the regular CC above Edited April 24, 2022 by Rodd 1 Link to comment Share on other sites More sharing options...
Rodd Posted April 24, 2022 Author Share Posted April 24, 2022 (edited) I know I screwed this up--as usual. But variations of screens and color calibration methods makes it hard to choose a course of action. Here is the final. Ended up the normal color calibration and less sharpening. Also--bin2 instead of bin3 Edited April 24, 2022 by Rodd 2 Link to comment Share on other sites More sharing options...
assouptro Posted April 24, 2022 Share Posted April 24, 2022 I like all three Rodd It’s really easy to get to a stage where you think you are finished and prematurely post only to see it on another screen and realise you aren’t seeing what you thought you had posted! really nice image, and such dedication! Thanks for sharing Bryan Link to comment Share on other sites More sharing options...

Thanks for sharing Bryan Thanks Bryan. You describe my routine perfectly. Part of the problem is I am so anxious to post, like a little kid running to show his mother the spotted newt he just caught. It’s silly, for if j haven’t posted an image in 3 weeks or a month, what’s a few more hours, or days even. 1 Link to comment Share on other sites More sharing options...
tomato Posted April 25, 2022 Share Posted April 25, 2022 Great result on a galaxy that doesn’t seem to get much attention from imagers. I also suffer terribly from the “I must post this now syndrome”. l think I should automatically defer from posting my first ‘final’ image as invariably I will produce two or three more later on which I will deem to be better than the first one.

Thanks Tomato. I made a rule awhile back that I wouldn’t post an image until 24 hours after I thought I was done. I never was very good at following rules!

Rodd Posted April 25, 2022 Author Share Posted April 25, 2022 I tipped over the paint can. It seems to be the popular choice these days. Link to comment Share on other sites More sharing options...
gorann Posted April 26, 2022 Share Posted April 26, 2022 All great images Rodd👍, maybe except the last one where you were not too kind to the stars... Link to comment Share on other sites More sharing options...
alan potts Posted April 26, 2022 Share Posted April 26, 2022 I prefer the lead photo, not a fan of in your face saturation, though having said that I often over do mine in an effort to cover up poor work. Alan Link to comment Share on other sites More sharing options...

Thanks Goran--by the time I got to the last version I am surprised it wasn't filled with shot gun holes. I fell off the wagon of multiple postings and ended up 2,000 feet down a ravine. A major problem I have to solve is my processing screen looks very bright. PI will say the background is .05/.05/.05 (similar to PS's 23/23/23), but it will look light gray. So I reduce it. By the time it looks good on the processing computer, it is almost pitch black on any other screen. It is very frustrating. On top of that, I have been looking at this miserable little patch of light for far too long, so I can't trust my eyes (or judgement). Thank god my wife locked my sledge hammer and maul in the shed, or I would be out one laptop (and maybe a few scopes). She is a wise woman. 1 Link to comment Share on other sites More sharing options...

Alan Thanks Alan--I agree. To put things into perspective, there are...oh, lets see....,maybe 40 versions prior to the last one. I am lucky it didn't end up chartreuse. Its funny you should mention adding color to hide poor.......data (poor work can be revised, but when the data is poor, not much can be done). I tried that approach with this target, never really feeling satisfied with the image. It didn't work. I would collect a bunch more data but I am not sure that would work either. 15 hours should be sufficient, and binned 2x2 it is really like 120 hours if you buy into the 4x rule (I don't). Then again, I never collected 120 hours of data. But if I did collect 120 hours of data and it ended up looking like this data set, I would turn chartreuse.
