Revision title: Pair of Jupiters with Io in transit

Acquisition type: Lucky imaging

My 2nd session with my new ASI462 camera on the C14. The seeing was better than for it's 1st light, but still very in/out, with focus changing minute by minute, making it difficult to determine best focus. Io and it's shadow were in transit, so I opted for a series of 2 minute SER videos, which I de-rotated in WinJupos before grading and stacking the best 20% in AS3!, with further derotation and stacking of the output TIFFs in WinJupos. Sharpening was done using wavelets in Registax6. The stacked image had a large blur where Io and it's shadow were in transit, so I pasted them back into the stacked and sharpened image from a single SER that represented the correct timestamp of the de-rotated image. Final colour saturation and levels adjustments were applied in Affinity Photo.

Io itself is somewhat lost due to poor contrast aginst Jupiter's bright cloud surface.

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.
