Moon on September 20, 2021 - Pythagorus under favorable libration

Acquisition type: Lucky imaging

The northwest region of the nearly full (99% illuminated) Moon from crater Pythagorus at the top to Sinus Iridium and crater Plato at the bottom are featured in this long focal length image captured the evening of September 19, 2021 (September 20th in UTC). Pythagorus has a more favorable perspective (allowing us to view the floor of the crater and its central peak) due to libration of the Moon.

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 30 ms. Stacking in AutoStakkert3 (best 25% of 1000 frames). Mosaic generated from 8 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.
