Acquisition type: Lucky imaging

Was not going to image this week due to poor forecast but decided to check the sky after realizing that the moon transit was on. Glad I did as the conditions were favorable with low surface winds and no clouds.

Started imaging just before 10:30pm AEST and continued until 12:30am producing 250GB of data out of which half was of usable quality. The seeing continued to fluctuate throughout the session, luckily some of the best stacks eventutated around midnight as Tethys began to slide in front of Saturn's cloud deck.

This view combines 12,000 frames over 43-minute period, the moon is visible as a bright dot on top of the image followed by its shadow at 4 o'clock. It is transiting southern hemisphere of the planet from right to left. In addition, two other moons are visible to the west of Saturn: brighter Dione and fainter Enceladus closer to the ring plane. As other observers have noted with bigger instruments, SEB appears disrupted. Centre of this activity is crossing the CM, northern latitudes appear relatively quiet.

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.
