M82- Cigar RGB + LHa

A multi night project where my vision was to grab a pure RGB capture at long focal length on the detail of the galaxy plus the dynamic Ha emissions.

Ha looked decent, RGB was ok, but combining the two just... lacked a bit of pop. So I tried something new to me and manually combined Lum + Ha and used it to bring out more of the Ha detail. It is tough to balance the dynamic colors of this target with the desire to make it flashy.

Pixel scale and seeing were below average which required multiple resampling steps. Makes it a bit softer than I would have liked and using an Ha filter at F/10... ugh (and apparently noisy without longer exposures, but that's why I typically would use the refractor for narrowband with its faster F ratio :-) - but I hope its interesting using a different take on the process.

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.
