Comet ATLAS (C/2019 Y4) on April 16, 2020

Captured this image of Comet ATLAS (C/2019 Y4) on the night of April 16, 2020. I only have an hour of imaging time between nightfall and when the comet passing behind some trees, so I wasn't able to capture many subs. Still, it was happy to see I managed to capture the comet. Sad that it is breaking up and we won't get to enjoy the show for much longer... This image was generated using my standard DSO processing flow, but I am working on learning on using the PixInsight Comet Alignment process to see if I can improve on the final image.

Imaged with WO GT81 at F4.7 (382 mm focal length) using Flat6A II field flattener/0.8x reducer, IDAS HEUIB-II (H-α Enhanced UV IR Blocking) filter, and full spectrum modified Nikon D5300. Total integration time of ~1 hours using 21 subs at ISO200 x 180 sec.

Pre-processed using PixInsight Batch Pre-Processing (BPP) script. Images calibrated using darks, flats, and flat darks. 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, ocal histogram transform, morphological transform to shrink stars.

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.
