Comet C/2020 F3 Neowise from Maryland on July 27, 2020 @~400mm

I was able to image Comet C/2020 F3 (Neowise) from my suburban DC backyard on the night of July 27, 2020. Between the light pollution in my backyard location, the ~30% illuminated moon, and the dimming of the comet, it was a lot harder to image than my first session about a week earlier. I was not able to find the comet in binoculars from my backyard, but the bright green coma was unmistakable in the images. My main goal of this session was to image the comet at longer focal lengths using my refractor. The coma shows some additional detail in these images, but like the camera lens pictures not much of the tail.

Imaged with WO GT81 at F4.7 (382 mm focal length) using Flat6A II field flattener/0.8x reducer and Nikon D750 with an exposure at ISO1600 x 15s. This is a stack of 25 images generated using Pixinsight. Images were alinged using the CometAlign process. Post-processed in Pixinsight: Cropped, gradient removal with ABE, MLT for noise reduction, 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.
