Jupiter and Ganymede: A Cosmic Game of Follow - Animation (23MB)

Acquisition type: Lucky imaging

On the night of 23 August 2023 I watched how Jupiter and Ganymede's shadow danced together and put up a show. So I decided to try and capture this game of follow from start to finish. The top moon is Io while the one below is Ganymede.

The time span of this phenomena was approximately a bit more than 2h, which started at 21:40 UT and finished at 23:45 UT on 23 Aug 2023. Since the seeing was a favorable 8/10 and a medium transparency of 6/10, I could squeeze decent details out of this project, considering that the first capture took place when Jupiter was at only 17 degrees high and gradually climbed to 39 degrees at the very end. Was very interesting to observe how details on the surface of the planet got better and better defined by the time it climbed higher on the sky.

This animation is made up of 64 individual video captures, 60s each, with no generated/interlaced frames in between. Each of these captures were stacked in AutoStakkert and polished in Registax. Due to the field rotation induced by my alt-az mount, I had to manually align each frame in Photoshop until I got the above result, which is scaled to 125%.

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.
