Comet 2023H2 from NightFall

Comet 2023H2 at NightFall. This comet, although not that bright, was moving really fast through the sky. That is why the nucleus in this image is a smeared line; 1 minute exposure times were too long to show the nucleus as star like, as it should have looked like. This is a composite image of an image aligned on the stars and an image created from the same data aligned on the comet. The telescope was unguided therefore it tracked the stars. StarXTerminator was used to remove the blurred comet images from the images aligned on the stars, and MaximDL was used to align and combine all the images of the comet. Then the comet image was copied on top of the star image in Photoshop, and the blend mode was set to lighten. This image was down sampled 2X for presentation, as it is pretty soft at full resolution and there isn't much detail in the comet anyway.

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.
