mattssporre Posted June 4, 2013 Report Share Posted June 4, 2013 Excellent image! How did you map the narrowband to RGB? If you used the hubble palette I would expect different colors, but maybe I just know too little about this object. BR Matts Link to comment Share on other sites More sharing options...
GeorgeCarey Posted June 4, 2013 Report Share Posted June 4, 2013 Great image! What I like is that you give the sky quality. Sometimes I see fantastic images and have no way of knowing if I could get something similar. My SQM varies from 19.4 to 20.0 so I have similar sky to you.
