First use of the Optolong L-Ultimate, captured over two nights of cloudless sky in November after a multi week streak of cloud cover... Unfortunately the transparency wasn't very good, but I wanted to try out the filter that I still went for it.

A ghostly region of dust ~550 light-years from Earth energized by the nearby star Gamma Cassiopeia (informally named Navi), the central star of the "W" asterism. This star has a rotational velocity of a little over 1 million miles per hour, causing it to bulge with an equatorial radius longer than it's polar radius. The nebulas are slowly being eroded by this stars ultraviolet radiation.

Due to being imaged with a 3nm filter, the reflection aspect of the nebulas are not prominent, making this a good target to get more broadband data for the nebula to hopefully bring out the blue from the reflected light from Navi.

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.
