Brian Maurer Posted July 30, 2019 Share Posted July 30, 2019 (edited) This is a Bi-Color using Ha and O-III. 400 each of 20 seconds. Shot on an 11”RASA with a ZWO1600mm. Gain of 300, Offset of 50. I’ve tried collimating, but I see it is still off. It’s not too bad, unless you zoom in on the stars. 4F3C3CA6-1B2E-4AED-90A0-832722DC3355.tiff Edited July 30, 2019 by Brian Maurer Attach a JPG 3 Link to comment Share on other sites More sharing options...
