I was going to start processing this over the weekend and realized that I had some PN signal in my red subs. Then I realized (obviously way too late): This object definitely has an Ha signal. Argh! I'm so anxious to publish something and move on that I decided to give it only one night of Ha (last night) and just roll with what I got (of course I also had to trash a third of my Ha subs due to PEC going haywire). I don't even think it's visible in this image. I probably could have done better if I had more patience or just grabbed more Ha instead of OIII. The OIII signal was stronger than I was expecting, and five-minute subs probably would have been enough.

I'm definitely in an astro funk right now. I still can't get my SharpStar working like I want to and I've been having a lot of other random issues - my EQDir cable stopped working last night, I had dew/ice on my sensor (I've taken a lot of steps to prevent that lately, but I did let the scopes run once a few nights ago when it was crazy humid out), my computer for my other setup keeps crashing, other gear not performing as expected, etc., etc. I've got some issues to hammer out over the next few days...

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.
