I had imaged the crescent this summer, but that was before I had received the adapter from Precise Parts that let me use my focal reducer or flattener. The corner stars were fairly distorted so I didn't upload it. Also, I didn't know about the soap bubble before, so this one is using the reducer so I can get it in frame as well.

Description: Just noticed a an artifact I accidentally introduced, so went back and fixed that. Should be pretty much the same otherwise.

Description: Another week of atmospheric rivers pummeling California, another week I reprocess old data. BlurXTerminator helps some of the details, but reducing the stars has more of an impact making the nebulosity stand out. Pixinsight's new SPCC also helped with more natural star colors.

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.
