Details:
This image shows what PixInsight's Dynamic Background Extractor does to an image. The amazing detail is brought out by balancing the background light such as caused by light pollution or breaking dawn in this case.Tech specs: Nikon d3500, Nikkor 180mm, f/2.8 @ f/2.8, iso 1600, stacked 18x25s raw, post-processed in PixInsight, Lightroom and Photoshop. Taken between 3:50AM to 3:59AM MDT.
F.O.V. is ~7x5 degrees. Comet's tail stretched at least 6 degrees in this uncropped image. The comet has changed since yesterday (exactly 24 hours earlier) but not significantly: www.flickr.com/photos/79387036@N07/50100826686/in/photost....
2nd image shows same stacking but without "DBE".
3rd and 4th show wide field using 85mm f/1.4 @ f/2.8, iso 2200, 5s.
