M106 and surrounding galaxies

I found this very difficult to process. I used Luminance and Ha from my 150P-DS (taken this year) but had to look deep in the archives and pulled some colour from my old Evostar 80ED and 533MC image here. The colour and stars were very challenging to bring together alongside the new Ha and Lum.

I've had a few attempts at processing this and can't quite get the colour I want for M106 and the other galaxies - something keeps giving up on me (aside from my skills

).

I really like the very faint cluster of galaxies to the lower left of M106 in this orientation. Known as ClG J1217+4730 - shown in the centre of the crop below and in the custom annotated revision. There looks to be another (separate) galaxy below this cluster (lower left in the crop below) but I can't find a designation for it.

Here's a crop of the Ha:

Primarily captured with ASIAir, pre-processed in APP and processed in PixInsight.

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.
