Nikon D850 and Nikon 70-200 f/2.8 lens


After getting some wide field shots of the comet before dark I zoomed in tight for a NEOWISE closeup. This comet and its tails are massive with a total estimated length of hundreds of thousands to millions of kilometres behind the comet nucleus. The nucleus itself is estimated between 5 and 10km in size. This is the result of 48 images over 25 minutes taken with my NIkon D850 and 70-200mm lens on my iOptron SkyGuider Pro tracker. Each image was 30 seconds, f/4, ISO 1600 at 170mm. I pre-processed and composited the images in Pixinsight and then did the final edits in Photoshop. Comets are especially tricky to edit as the comet is moving at a different rate than the stars relative to the earths rotation. In order to process the image you need to stack for the stars and blur the comet and then stack for the comet and blur the stars and then combine and do final edits.
