Description

Another image of Comet Neowise taken the Howard County Conservancy North of DC on the night of July 18, 2020. Most of the images taken during this session were taken through some haze and passing high clouds. This is another capture taken with the Nikon D750 and 28-300mm zoom from a fixed tripod. I can just make out the green coma other folks have reported/imaged.

This capture was taken around 10:15 pm. Imaged with a Nikon D750 and Nikon 28-300mm at 200mm and F/5.6 with an exposure at ISO6400 x 2.5s. This is a stack of 30 images generated using Pixinsight. Post-processed in Pixinsight: Cropped, gradient removal with ABE, MLT for noise reduction, photometric color calibration stretched using masked stretch, Curves Transformation, TGVDenoise for noise reduction, HDR transform, Local histogram transform, morphological transform to shrink stars, and color saturation boost.
