C/2017 K2 (PanSTARRS) Comet with M10 Cluster - 07/15/2022

C11HD Hyperstar v4
540mm F/1.9

First light with new ZWO ASI585MC camera, as my ZWO ASI2600MC Pro camera is being replaced.

Calibration, stacking, registration, normalization, integration, background extraction and color calibration done in Astro Pixel Processor.

First, stacked on stars and processed to save star field. Removed stars in PixInsight with StarNet2 and kept starfield and processed stars.

Second, stacked on comet nucleus for the comet, but got star trails. Re-integrate using weighted median absolute deviation local normalization rejection to reduce the star/trails.

Take comet stack into Photoshop and clear out star trails leaving only the comet field.

Bring comet stack back into PixInsight and use PixelMath to re-integrate starfield.

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.
