NGC 1499 The California Nebula - Two Panel Mosaic

The California Nebula is an emission nebula, about 100 light years in length, located about 1500 light years from Earth in the Orion arm of the Milky Way. The star most likely providing the energetic starlight that ionizes much of the nebular gas is the bright, hot, bluish Xi Persei, seen in the photo, just below the nubula.

This is a two panel mosaic taken with a wide field side-by-side rig that I've been building.

The scopes are a Sky Watcher Esprit 80/400 and a Takahashi FX60CB at 375 mm with the 1.04x field flattener. As the Tak is slower (F6.2 vs the Esprit F5) I put a Ha filter in its optical train while the Esprit did SII and OIII using a 5x EFW. Test shots showed that there was good detail in the SII but almost none in the OIII, so OIII was binned 2x2 and fewer subs were taken.

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.
