The Orion Nebula in HaOiiiRGB

Only had two nights between atmospheric rivers passing through from the Pacific really challenging the idea that Arizona is clear and dry, but was enough to shoot the Orion Nebula as it is one of the brightest things up there. I had to use super short exposures (30 seconds) to avoid blowing out the core - for a total of 900+ shots at around 8 hours over two nights. Really love that I got to keep the trapezium in this shot. There's a lot that could be better about this one, especially the fact that this was my last shot I did before installing a primary mask, and Hatysa really shows it, but it's always best to post something so you can come back to it in a year and see how you've improved. Despite folks suggesting people start out on M42, I find it one of the most challenging things to shoot - it has it all in one image -- extremely bright core, very faint wisps, bright stars demanding perfect collimation, and enough broadband signal that doing a quick HOO + RGB stars leaves a lot wanting. It's a hard target! Glad I got to try it this year though.

Probably one of the last big ticket shots I'll be able to do before our Milky Way disc kind of fades out of view in the spring and Galaxy Season starts, when our night sky looks out of the Milky Way into the wider universe instead of through it.

In addition to the short broadband exposures, I got an additional small amount (1.6 hours) of narrowband data to add in via continuum subtraction.

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.
