The M81 Galaxy Group Through the Integrated Flux Nebula

This was imaged on 021216 from an LRGB Set of astrodon filters.

39 900 second Luminance subs.

18 300 second Blue subs.

19 300 second Red subs.

14 300 second Green subs.

Corrected imaging time approximately 13 hours.

NGC 3077 is on the bottom of the frame which is something I don't see often in this galaxy duet.

I may try an attempt as well to process to bring out the IFN ; although of course it will blow out all inner detail on M81 and M82. I can attempt to hold down that as much as possible by application of several overlay masks.

I am posting an updated version of this image from studying many hours in Pixinsight 1.8 and using Warren's videos. Also a big thanks goes out to LLoyd in holding my hand in the beginning steps of grasping some of these concepts in Pixinsight. This is an updated image showing much better detail, contrast, IFN, and great alignment.

I've worked much more into Warren's teachings in PI and have done some more refinements; thus another update to the M81 IFN. This final image was all done in Pixinsight 1.8 and I can say this is the definative program for astroimage processing.!!

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.
