NGC 1499 (California Nebula) HOO with RGB Stars

Revision title: 2024 Reprocess

This was the final image I acquired time on using my Astroberry setup, in December 2022 & January 2023. The camera needed rotating 90 degrees, and I had some serious tilt issues, which I couldn't track down or alleviate in any way, so it is what it is. I grabbed RGB stars in January 2023 before switching to the ASIAIR for acquisition.

I was pleasantly surprised with the brightness and detail in this target. It was a pleasure to process, and Bill Blanshan's equalization script helped bring out the otherwise weak OIII. This was processed entirely in Pixinsight without bringing it into Photoshop, including painting out the halo and artifacts around Menkib.

I hope to revisit this target in the fall, and bring up the total integration time a bit - terrible weather cut winter astrophotography shorter than usual this year. Maybe by then I'll have sorted the tilt!

Title: 2024 Reprocess

Description: Complete reprocess, with new BlurXterminator AI to help with severe tilt and GHS stretch to improve nebula detail. Stronger Ha signal, weaker OIII compared to last time. Curious comet (?) above and to the left of Menkib...

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.
