m81_82(Bode's galaxies) HaL_HaR_GB + I.F.N.

m81_82 captured in HaLRGB and processed in HaL+L synthetic for luminance layer and in HaR_GB for color layer. Star color are built from RGB layer only.

Final revision with luminance captured with lens 200mm f/2.8 to get more I.F.N. signal.

My longest exposure time integration and processing time as well!!!! I am rewarded with visibility of I.F.N. (Integrated Flux Nebula). Moon light was not that favorable during those sessions so I started first with Ha filter mid of March and finished with luminance one on 4th of April to get as less as possible impact.

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.
