NGC 7822 SHO

The Arizona monsoon seems to be winding down which finally allowed for some decent imaging time. I set my sights on NGC 7822 and processed this version using a modified SHO palette. I continue to struggle with fine tuning the adjustments for my image train with the combination of the Blue Fireball camera rotator and Hotech flattener. The stars continue to be problematic on account of backspacing and potential tilt issues.

Needless to say, I've been learning some new Pixinsight techniques in an effort to correct the weird shapes. I received some nice feedback on my previous image and incorporated adding luminance from my Ha channel back into the RGB stars which definitely helped. Long term, I still want to fix the root cause of the problem - perhaps I'll ditch the rotator on my next session so that I can rule out whether that is causing the problem.

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.
