Jovian Moons 10-22-2022: Shadow Transit & Emerging from Eclipse

Acquisition type: Lucky imaging

A short animation showing the end of Europa's shadow transit followed by the emergence of Ganymede and then Io from being eclipsed by Jupiter on Oct. 22, 2022. I captured this sequence from my home in Hilo, HI, with a C11, Siebert 1.7x modular barlow and an ASI224MC camera over 43 minutes elapsed time. I made 90 seconds video captures of the shadow transit using an 800x600 ROI. I happened to check Stellarium and discovered that Ganymede and Io were both being eclipsed by Jupiter and would appear as the shadow transit was ending so I changed the ROI to 1024x600 to be able to have them in the FOV. I used Winjupos to "derotate" each of the single images out of AutoStakkert!3/RegiStax6 to have them all the same size and orientation.

I had to delete a few of the images due to problems so the animation is not as smooth as I would like but it does show the emergence of Ganymede followed quickly by Io. Interestingly, the shadow of Jupiter seems to show up better on Ganymede during the reverse play of the animation.

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.
