Popular Post +RonC Posted September 22, 2020 Popular Post Share Posted September 22, 2020 (edited) Although this target was quite low and over the town centre I thought it was worth a another try! 40 x 180s at Unity Gain with the usual kit.

Clive Posted September 22, 2020 Share Posted September 22, 2020 Nice one Ron. There seems to be quite a lot of detail 'hiding' in the light pollution and I suspect applying a gradient removal tool first would allow it to be pulled out. +RonC 1 Link to comment Share on other sites More sharing options...
+RonC Posted September 22, 2020 Author Share Posted September 22, 2020 (edited) I can't get Gradient Xterminater to work as it's a 64 bit program and my PS6 is only a 32 bit Program!! I'll have a play later to see if I can get more out of it! Edited September 22, 2020 by RonC Link to comment Share on other sites More sharing options...
Clive Posted September 22, 2020 Share Posted September 22, 2020 Can't you use another package just to remove the gradient prior to continuing with your normal processing in PS? For example, you could import the TIF or FIT file from your stacking software into IRIS, apply the gradient removal tool from the processing menu and save the result as a TIF or FIT file for further processing in PS.

+RonC Posted September 22, 2020 Author Share Posted September 22, 2020 Not tried Iris, sounds a good idea though!👍 Link to comment Share on other sites More sharing options...
Popular Post +RonC Posted September 22, 2020 Author Popular Post Share Posted September 22, 2020 OK, tried that and the proof is in the image! I didn't understand Iris so that's another learning curve but I did a gradient removal (basic).

Clive Posted September 22, 2020 Share Posted September 22, 2020 Well, for using IRIS for the first time straight out of the box, I would say that's a result! It certainly appears to me to be an improvement in terms of the galaxy detail. When you've got a large target like that, it's best to use a mask to 'hide' the galaxy otherwise IRIS includes it in the sky background calculation (which is why I suspect the corners are bright using the default settings). Without a mask, I would set the background detection and the fit precision both to low. (but with 3 options for both, you've got 9 options to try!) +RonC 1 Link to comment Share on other sites More sharing options...
