EDIT: I forgot that I had a couple of hours of RGB on this target from a week ago. It was a little bit more out of collimation so I wasn't going to use it. I added it for the second revision and I think it really helped out the color balance. Goes to show that integration time trumps most everything else.

Second light with my new Powernewt. I'm still learning how to collimate this scope and I'm getting better but still have a ways to go. (After this image session I found that one corner of my focuser was not drawn tight to the OTA. That helped a ton with my next captures, but did not benefit this data any) I had a lot of challenges getting this data. The seeing was terrible and the dew was so heavy that it was almost like mist. My secondary kept fogging up, and I think my red channel focus was off a tiny bit. Also my camera window fogged up, which I hadn't experienced before. Manual calibration with PI produces some VERY strange results so I need to see where I went wrong there. I ended up running each channel through BPP which fixed all the problems I hit with Manual Integration, but resulted in a lot more noise. I'd call this a WIP, but having fun with the new scope and enjoying the challenges.

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.
