Double cluster reprocess with PI - calibrating star colours with PhotometricColorCalibration

I gathered this data a couple of months ago using my 70mm apo.

The challenge here is in the processing. I'm just beginning to get comfortable with processing using Pixinsight. Slowly getting the hang of it I think. In this image I tried to use the fantastic resources available to accurately calibrate the star colours. PI is so powerful!

EDIT:

P.S. I used PhotometricColorCalibration with the average spiral galaxy white reference. To allow the software to 'find" the field, it was important to note the details (correct time, etc) of the image capture.

A detailed description can be found here: https://pixinsight.com/tutorials/PCC/

PI notes that his tool is designed to be applied to "linear images" that have been acquired through filters with relatively wide passbands, which is similar to those used by the APASS catalog.

Thanks for looking.

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.
