A single-frame/mosaic hybrid. The combination of GFX-50R and GF250mm/F4 (at F4) is a single pointing composition, while the combination of D800 and RedCat is a two-frame mosaic. The combined FoV of a D800+RedCat two-frame mosaic is similar to the FoV of GFX+250mm.

Rev.C is a single 5-minute exposure from GFX. In the white circle is Ceres, the largest main-belt asteroid. Its magnitude on the day is 7.6. It no longer appears in the deep stacked image, because it moves very fast, and therefore it was removed by sigma rejection during stacking.

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.
