Astrobdlbug Posted February 13, 2021 Share Posted February 13, 2021 (edited) Hi all, getting late but been working on this all evening - didn't thinkn I would get an image out of the data aquired last Wednesday night as something has gone a bit wrong with my setup and focus is not consistant accross the image plane - think it may be that the lens has moved and the scope ring I use to stabilise it slipped so there is tlit somewhere. So the image has a few dodgy stars around center and right - but if you dont pixel peep - the widefield experience is still available 🙂 I have also mixed in some higher resolution Ha taken of Cone Nebula and Rosette with my AT106EDT in 2018. I had planned to do a 4 pane mosaic, but aformentioned focus issue curtailed that - so this is 3 panels Samyang135mm F2 ASI1600MM Optolong Ha & Oiii 45 X 240s Ha 45 X 240s Oiii I used a HOO pixel math equation set that I found on coldest nights webpages Ha/Oiii : R = Ha G = ((Oiii*Ha)^~(Oiii*Ha))*Ha + ~((Oiii*Ha)^~(Oiii*Ha))*Oiii B = Oiii Processed with APP, Pixinsight and Photoshop Bryan Edited February 14, 2021 by Astrobdlbug Updated watermark position on AstroBin 4 Quote Link to comment Share on other sites More sharing options...
