I targeted NGC7822 for no reason in particular. 4 weeks into the project, I noticed the face and became obsessed with it.

This is a massive mosaic of 200 5-minute and 300+ 2-minute subs in H-α, plus a few 100 second experimental stranglers. And 1680 seconds (340x5sec) RGB unguided for the stars.

The amount of optical aberrations, amp glows, hot pixels and star elongation that got eliminated by integrating 500+ subs is unbelievable.

I feel a sense of accomplishment, but I think I'll stick to easier targets for the next couple of decades.

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.
