Popular Post +Graham Posted April 22, 2020 Popular Post Share Posted April 22, 2020 The learning curve continues with this LRGB lark. Reducing the length of the Lum subs by 100 seconds made a huge difference to the quality of the subs. Will try a further reduction to all the sub lengths next time out. Managed to get a couple of images last night. Taken with the GT 81 QSI 683 Captured calibrated and stacked in Maxim Compiled in PS 6 Click on an image a couple of times to get to full res. M101 21 lights at 180 seconds binned 2x2 11 subs in RGB at 300 seconds per channel binned 2x2 21 Darks 21 Bias 21 Flats in each channel M81 and M82. 21 lights at 180 seconds binned 2x2 11 subs in RGB at 300 seconds per channel binned 2x2 21 Darks 21 Bias 21 Flats in each channel Clive, +Glafnazur, Bottletopburly and 3 others 6 Link to comment Share on other sites More sharing options...
+Ibbo Posted April 22, 2020 Share Posted April 22, 2020 Graham keep an eye on the histogram in maxim . I did some on M104 (maybe just a tad low from here) with the RC and the L was too much at 600secs and I reduced to 300 last night and still think they may be blown out at the core. +Graham 1 Link to comment Share on other sites More sharing options...

Will do, I noticed with M81 it was blown out. I will reduce it again tonight. Link to comment Share on other sites More sharing options...
+Ibbo Posted April 22, 2020 Share Posted April 22, 2020 I think we have been so used to narrowband taking eons and we have had a run of nights in galaxy season where Lum is king. I'm not complaining at all cloud gods. Link to comment Share on other sites More sharing options...
+Graham Posted April 22, 2020 Author Share Posted April 22, 2020 This is the first Galaxy season I have ever used LRGB in anger. Whole new ball game isn't it 😅 Link to comment Share on other sites More sharing options...
