While waiting for full darkness, I got started on another Moon image. It is fun learning to use SharpCap. One of these days I need to try putting the camera behind a Barlow lens, but right now I don’t want to mess with the deep sky target configuration. For fun I tried drizzling and that REALLY slowed down the processing. It’s sharper than my previous Moon attempt, but that might just be difference in phase or perhaps from being more selective about frame quality (and of course seeing always plays a huge role). I’ll have to do some experimenting with these data to see if it was worth the extra effort. I was way more conservative with the “mineral” saturation enhancement than before, and even though the colors don’t show up as much I think I like this better.

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.
