M82 LHaRGB - The Cigar Galaxy

M82 was a quite laboured work. It started of quite easily in 2005 (unguided shots). Then I realised that I would need to use H-alpha to bring out the HII jets and started collecting H-alpha in 2007 (guiding), first with 5 min subs then (not enough SNR!) with 10 min subs until in 2009 I was entirely fed up with it and drew a line; that was it, good or bad. And so here it is. Small fray compared with today's images I assume but was a good rendering with good resolution back then.

M82 is a good contender for the longest imaged object ever (from me). Reason being that I tended to use prime imaging time for hi-res imaging, lousy conditions for colour binning and strong moonlight for H-alpha. So anytime I didn't have much else to go for I plumped for either M82 or M57. Obviously the H-alpha exposures are blended into both Luminance and the red channel.

As an image for first day of the year I'd say that a starburst galaxy is a fitting match.

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.
