I recently published a well-received version of M81, it seemed rude not to process its compatriot.

In order to realise all the details you could argue the image is actually a L, L, L, L, L, L, L, L, L, L, Ha, Ha, Ha, Ha, Ha, RGB, RGB, RGB, RGB, RGB, RGB, rather than just a HaLRGB image!

In order to realise all the details I have been persisting with my (very time-consuming approach) of building the main layers from multiple stretches of the main frames from very dark to very light, a manual HDR (but with full control) most of the work is done in PI but the layering and masking has to be done in PS for control. I am finding at the longer focal lengths this really lets me realise all details from the dark (often washed out by brightness on such targets) to the very light, I can even stretch beyond the limit to realise the fainter details.

Anyway, hope you all like - not a quick process taking about 8 hours solid to process over a few days.

As well as realising some great detail I was pleased to see the inner structures showing well including the mushroom shape to the right and the double boundary of the left side (inner ring just about visible)

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.
