Greg Yancey Posted November 23, 2022 Share Posted November 23, 2022 (edited) Had a go at M42 last night and was able to frame it so that I got Sh2-279 in the picture as well! It was perfect skies last night and I had to take advantage of it as we have been having alot of cloud cover lately. Took 90x120 sec shots using my C11 with Hyperstar C11v4, ASi294MC Pro and IDAS NBZ UHS Filter, and processed in Pixinsight Clear Skies Edited November 23, 2022 by Greg Yancey 3 Quote Link to comment Share on other sites More sharing options...
Astrobdlbug Posted November 23, 2022 Share Posted November 23, 2022 Hi Greg, nice framing - try to apply some SCNR and remove Green, and then balance the background There is also a neat script for Pixinsight written by Russ Croman called ColorCorrectedHDMRT, you could use that on a less stretched version and it should reduce the way the core that holds the trapezium which is blown out and over saturated. M42 is a really difficult target to process, because its so bright its a relatively easy target to image in a short time , but the processing can be massively frustrating, Give it another go, I am happy to answer any further questions Bryan 1 Quote Link to comment Share on other sites More sharing options...
Greg Yancey Posted November 23, 2022 Author Share Posted November 23, 2022 (edited) Thanks so much Bryan! I will give it a try, I am still playing around with it and will try that....when I apply SCNR, I can never tell if the green goes or not as I am colorblind.lol....🙂 🙂 I try to match to other pics the best I can, which has really helped me learn PI. Thanks so much for the info for the script, I always like new ones that help out the processing! 🙂. I will check that one out, I recently downloaded the ones from Bill Blanshan and love those! I know, when I am processing this one I was trying to play with the stretch to keep the core a little dimmer.. 🙂. Thanks so much for the comments 🙂 I really appreciate it 🙂 Edited November 23, 2022 by Greg Yancey Quote Link to comment Share on other sites More sharing options...
MartinS Posted November 24, 2022 Share Posted November 24, 2022 Hi Greg, you may find it’s worth imaging at 1 min or 30sec especially with a hyperstar/C11. The core is overexposed with your setup at 2 mins. 1 Quote Link to comment Share on other sites More sharing options...
