The Moon’s eastern limb, shortly after full moon - 20221012 00:30cedt

In my previous posts, I had detailed images of Petavius and Langrenus located near the Eastern limb of the moon, shortly after full moon to see the shadows cast by these crater walls, as the most favourable time is either when the moon is 2-3 days old, or shortly after full moon.

First time I imaged the moon with my TS102 in ‘moon’-configuration, straight focal length (FL1100), with an IR685 filter. A composite mosaic of three images, not all too well aligned, but I specifically catch the eastern limb

TechnoSky102/1100, ASI 178MC, IR685, EQ6R-Pro
20221012 1080p 8ms G200 60s 1200 frames, 50% stacked - each
AutoStakkert, PixInsight, Lightroom

This is giving me one of my most detailed and sharp images of the moon's eastern limb to date. On my other posts, I tried to go ‘deeper’ by using a Barlow 2x and 3x, but this is pushing the limits of this ’small’ achromat scope, especially with the smaller pixel-size of the ASI178MC. These test-images have given me the insight for future images to switch to the ASI174MM and limit the magnification to B2x maximum (FL2200mm, f22).
Happy with this result …

Any constructive guidance is welcome …

Clear Skies everybody! 🤩✨🔭

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.
