NGC 7822 SHO

I struggled with this one, tossed roughly half of the SII and OIII subs out for two reasons. On the first night I shot Ha with no issues. I grabbed the wrong frame from Ha to platesolve on the second night ( I had moved the mount to better center the nebula and grabbed a frame prior to the move). Secondly, I started to get star trails after 6 subs, guiding assistant showed polar alignment way off. Re aligned, after a few subs trails again. Polar alignment off again. Found a slight amount of play in the dec and had to adjust the worm engagement to get rid of it. I also found some play in the guidescope. Both the mount bracket and main scope rings are threaded and for some reason it had came loose. I could not get it to tighten back down, each time I tried there was one thread between the main scope rings and guide scope plate allowing a slight amount of wiggle. I drilled the threads out of the plate and bolted it back down adding washers. Super tight now and guiding has been between .44 and .56" since.

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.
