12 panel mosaic of California Nebula

I think monochrome images are still beautiful and can be appreciated very differently from color. After doing several 2x2 mosaics this summer, I wanted to push a bit and do a larger one, so I targeted the California Nebula. My aim from the start was a monochrome image, and I wanted to show the nebula in context, surrounded by emptiness. I didn't expect to find the faint arc of Ha that is in the top left of the photo, so there is definitely more out there to discover.

A mosaic this size can be forgiving - I shot 1 hour each panel in Ha, knowing I could absorb some noise because I would downsize the final image by at least 50%.

The panels were integrated in PI, run though Graxpert for gradient reduction and conversion to .fits, the mosaic itself assembled in AstroPixelProcessor, and then post-processed back in PI.

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.
