Comet Atlas at 0.5"/pixel

This is Comet C/2019 Y4 (ATLAS), captured on April 12, 2020.

This is my first attempt at imaging a comet using mono CCD.

I captured 8 300" images per channel in interleaving fashion - i.e. RGB RGB RGB etc.

I normally use Kstars for imaging, but it does not look like it supports capturing images in this fashion easily, so I used CCDCiel.

All processing was done with Pixinsight.

I registered and integrated the images using two methods:

1. regular star registration

2. comet registration

Once both of the images were processed, I combined them using PixelMath.

Even though there are some challenges with using mono CCD, it seems to be better than using RGB camera. Due to channel interleaving, the stars on comet registered channels are nicely separated and thus are easier to remove using pixel rejection algorithms.

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.
