NGC1499 California Nebula 9 Panel Mosaic

My first mosaic attempt, and by far my toughest project. This project was shot over over multiple nights from November to the end of December, 2021. The project consisted of 9 panels with my 800mm FL Newtonian Astrograph. Total integration time is approximately 174 hours between all panels and channels, but I did not keep track of those very details. The Ha and SII channels from acquisition to processing were fairly reasonable, besides time consuming, but the OIII channel just wasn't working with me. I struggled quite a few nights between clouds, to calibration of the frames (this QHY294M is giving me fits), and the combining of the panels for the mosaic was really daunting. But it paid off in the end. I learned a lot, especially patience. This wont be my last mosaic by any means, as they are really challenging and rewarding.

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.
