IC 1805 - Optolong L-Ultimate First (processed) Light

Revision title: IC 1805 - 2022 data, 2023 process

I received the Optolong l-ultimate filter at the end of September. Between smokey air, clouds, guiding issues, and spending clear moonless nights with my new monochrome kit, I hadn't the data gathered to really publish an image with this filter. Now my OSC is hobbled with cooler issues. So this is what I ended up with.

Title: Photometric Color Calibration version

Description: My original version of this image used a PI "linear fit" work flow for color calibration. I liked the colors in the core, but the stars end up a turquoise to teal color. This revision employs the PhotometricColorCalibration process.

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.
