Comet C/2020 F3 Neowise from Maryland on July 18, 2020 @300mm

My final 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, this time at a focal length of 300mm. 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 300mm and F/5.6 with an exposure at ISO6400 x 2s. This is a stack of 25 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.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
