Pickering's Triangle

A project from last year, this ended up being a disaster due to a rotational shift in my imaging train at an unknown time, resulting in bad flats. I finally decided to revisit the data, and see if I could acquire some flats that would work. While not perfect, and many subs were lost, I did manage to salvaged the image. Not quite as deep as I was hoping for...the intricate and delicate twists and filaments of structure in this object are truly amazing.

Full SHO, from 4 hours Ha, 5h10m OIII and 7h20m of SII (out of around 10 hours of data actually acquired for each). Minimal processing...simply integrated, combined with PixelMath, slight sharpening and extremely minimal background denoise with MMT, and a simple stretch.

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.
