Acquisition type: Lucky imaging

Until now it was not possible to produce a mosaic of more than six consecutive panels. On October 27th, for the first time, I could put together a 20-panel mosaic with only a single small cloud trespassing. The result is an image 9,000 x 9,000 pixels in size (1.5x drizzled). Captured in near-infrared (IR742nm) at FL=1500mm with 6ms exposure time at gain 200, 170fps the mosaic is composed of 400 frames each in mono-8, 10-bit ADC. The planets taken on the same evening are inserted to scale. Please zoom in and pan around.

Frankly, I am on the fence with drizzle. The larger images resulting from 1.5x drizzle bring advantages for, say, presentations while undrizzled images are sharper with higher contrast (not too much difference though) but you when you zoom in on a HD monitor you always go beyond 100%. Any views are welcome.

The images in the revision are taken at FL=1500mm. Since the air was quite unstable I decided to employ the 742nm filter instead of the 642nm. Though not at its maximum, libration was favorable in both, the north and east. I like the Beach Boys' song "Good Libration".

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.
