Schiller / Bayer / Rost / Zucchius craters

The primary feature in this image is Schiller crater, located at the center. Though I have seen many excellent images of this crater by others, before capturing this data and staring at it myself, I had not fully appreciated just how oddly shaped this Schiller is. I had assumed that, since it was near the visible edge of the moon, I was just viewing it from an oblique viewpoint which was exaggerating its shape. It really is more than nearly two and a half times as long as it is wide! Nearby craters Bayer and Rost provide a good comparison in terms of shape; Zucchius can be seen in the background (at the very top of the image).

This image was captured using my C8 SCT telescope with a 2x Barlow and ZWO ASI 178 MM camera. We had an unusually calm and warm start to February here in the Bay Area, and seeing and transparency on this night were nearly perfect, which is rare for this time of year. Hence, any problems with the image were self-inflicted!

The moon was 88% illuminated for this image, and about 70 degrees above the horizon. For the image, I captured 10000 frames, stacking the best 35%. Gain on the camera was set to 310, with an exposure time of 3.6 ms.

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.
