Acquisition type: Lucky imaging

Imaged the northeastern quadrant of the first quarter moon (45.8% illuminated) in this long focal length panorama captured the evening of July 16, 2021 (July 17th in UTC). The seeing and transparency were excellent this night and I ended up with some of my best 'hi-res' lunar imaging results. This is a local crop from the overall panorama. Mare Frigoris runs through the north of the image, with prominent craters Aristoteles and Eudoxus to the east, and the famous Alpine Valley to the west.

Imaged with a C8 Evo, ZWO ADC, Baader 685nm IR pass filter, and ZWO ASI174MM. Imaging train was configured to give ~F/20 (~0.18 arcsec/pixel). Image capture using Firecapture with gain set at 250 and an exposure of 12.5 ms. Stacking in AutoStakkert3 (best 25% of 1000 frames). Overall panorama generated from 26 panels using Microsoft Image Explorer. Wavelet sharpening and histogram adjustment in Registax6.

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.
