Ursa Triplet - M81, M82, NGC3077 in LHaRGB

Kicking off galaxy season with an absolute classic - the triplet of M81, M82 and NGC3077 in Ursa Major.
I'm preparing getting a longer FL refractor to hunt these down properly, but in the meantime, the 550mm Esprit 100 has to suffice.

I'm not a fan of luminance data it seems, especially at the same subexposure length as RGB. The stars bloat a lot more and combining data is a struggle everytime.

The IFN came through thanks to the long integration time. I did not push it too much, though. It is a very dim part of the image and the processing should reflect that (pun intended).

Description: Dialed down the noise reduction and revived Holmberg IX.
Color balance should be better now as well.

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.
