Acquisition type: Lucky imaging

..., I'm trying to image planets. Although the weather forecast was predicting a clear sky for last night, it turned out that faint clouds covered the sky, preventing a good transparency. Nevertheless, I wanted to give this a try and see how my modified auto focus on the EdgeHD performs and also test the process of planetary imaging again.

Saturn is far too low on the horizon (and not even visible from my telescopes location due to obstructions). Since I don't have an ADC (yet), I have to constrain myself to planets high in the sky and so Jupiter was the logical target. I also captured data of Uranus but I think there's nothing to make out of the data.

Since Jupiter's rotation is very fast, I limited myself to sequences of 3000 frames at about 67 frames per second. As usual, focusing isn't trivial and so I collected several sequences with a slight focus adjustment from sequence to sequence. The images shown are from the best raw data that I was able to gather. The sequences were integrated with Autostakkert and sharpened using waveSharp. Cosmetic processing was done in Affinity photo.

I still have to learn a lot about planetary imaging and might need to add a barlow lens (with a very slight magnification) for a slightly better sampling.

Feel free to give me feedback on the image.

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.
