This was going to be a HA/OIII image but unfortunately I can't really go any further with it as the data is flawed and I'm going to have to start over again. Initially I was really please with the data but as I started processing I noticed some horizontal banding which I've never seen before. I tried new calibration but it just made it worse. After much head scratching I've finally figured my power supply is failing. The voltage is very slightly fluctuating which I'm certain is the root cause. So new power supply ordered, hopefully it will arrive in time for the next clear sky.

Updated: Added a second night of imaging taking integration up to 8 hours. Camera banding issue sorted, you can still see it a bit but new data has mostly drowned it out.

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.
