Comet C2018 N2 ASASSN

I did not intend on imaging this object. Before I went outside I decided that I would try and image either the Cocoon Nebula or the Elephant's Trunk Nebula. I was going to check where each object was in the sky and how close they were to meridian. However I noticed Pegasus and remembered

last night how many hours I spent trying to locate the comet without success. My ego had been damaged. So I thought let me just spend a few minutes to see if I could find the comet. I checked a star chart to see where the comet was located. I put my red dot finder on the spot where I thought the comet should be and took a test image. The comet was in my image. So I decided to image it. It was clear when I set up my equipment. However after taking two light frames the sky clouded up and I fought with clouds the rest of the night. This comet is relatively dim at magnitude 12 and it is very small compared to other comets I've imaged.

Description: I completely reprocessed my image. This time I chose images to align and stack where the comet had not yet reached the two small stars to the left of the core of the comet. The change is subtle but to me the comet looks better in this image.

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.
