M31 - LRGB + SHO

The Stairway to Heaven of astrophotography—this target has been shot more than a revolving duck at a cheap traveling carnival. So how is a poor farmboy supposed to make it interesting? Maybe by shooting a full palette of narrowband with plenty of Ha—lots of Ha. You decide.

I regard this as a multi-year project, so the 56.2 hours you see here is just the beginning. But I hope it's an interesting beginning. To me, it's not enough to add hydrogen-alpha, and maybe some ionized oxygen, to the frame. I wanted to see what it looked like with what must be thousands, or even millions, of Hubble-palette-ready narrowband nebulas factored in. And I wanted just a touch of our intragalactic Ha to show up to put it in proper context. So here it is. Much more next year—and, hopefully, for many years after that.

Description: The final product on Astrobin seemed to me to come across as a bit too red on my other devices, so I backed off the red in the broadband segment just a touch.

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.
