Learning how to capture and process a comet! @Adam Block's new comet tutorials and the updated CometAlignment PI process have been extremely helpful.

For this image, I captured ~100 90-second OSC frames in relatively poor seeing and average transparency conditions. Ended up using about 60% during Image Integration for a cleaner result.

My high-level workflow:
- Calibrated with WBPP
- Extracted stars-only image w/SXT and processed separately
- Extracted comet-only images with SXT batch processing
- Comet Alignment and Image Integration of comet-only images, processed resulting image
- Merged two images with Pixel Math, cleaned up

I'm also working with a fresh RGB set captured by my mono cam using fewer, longer subs. Will post that one if it turns out well.

Description: Reprocessed so that stars-only image was generated using comet rejection (comet alignment + local normalization + image integration), which picked up at least one galaxy in the background. Adjusted comet's color saturation using white balance levels from SPCC on stars-only 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.
