don4l Posted November 13, 2020 Share Posted November 13, 2020 This image has much more exposure time than I usually manage. The extra exposure time seems to have paid off as it has come out much better than I expected. So, in future I have to be a bit more patient and go for longer exposures.225m Ha, 455m OIII (2 x 2) and RGB 3,3, and 5m for the stars. Starnet++ was used to remove the stars from the narrowband data. For some reason, this left greenish "holes" where the stars had been removed. Thes holes were filled in by using the new stars as a transparency mask and just sliding a duplicate of the image underneath until most of the holes were filled with a nearby patch.Camera: G2 16200, Scope FSQ106 at F3.6, Mount EQ6.Acquired with CCDCiel, Calibrated, stacked and colour combined in CCDStack. Processed in Gimp. 4 Quote Link to comment Share on other sites More sharing options...

For some reason, this left greenish "holes" where the stars had been removed. Looking good. On some images I find that applying Starnet++ on a partially stretched image, produces a better end result, than fully stretching, then applying Starnet++ Quote Link to comment Share on other sites More sharing options...

The OIII data was stretched much more than the Ha.I'll try removing the stars earlier next time. 2 Quote Link to comment Share on other sites More sharing options...
Gina Posted November 14, 2020 Share Posted November 14, 2020 Nice one ? I too have found Starnet++ works better on unstretched or only slightly stretched data. Quote Link to comment Share on other sites More sharing options...
