Between our own galaxy and M82 there is a large amount of dust, which (illuminated by our Milky Way) is also named "galactic cirrus". Optically it looks as if the Cigar Galaxy is embedded in it, but this is de facto not true.

What I noticed in some images with very long integration times in H-Alpha (also here on Astrobin) is that the reflected light of the cirrus is mixed into the red part of the burst region in M82. But this should not be correct in any case, because the haze of the cirrus and M82 are much too far apart. Probably the continuum light of the cirrus was captured by the H-Alpha filter during the long exposure times. Of course this light is not part of the H-Alpha region of M82. In the end the image processing was a fine balancing act in this case. Hope this is a helpful hint for some of you and that you enjoy my version of the Cigar Galaxy.

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.
