Io transit of Jupiter with a small refractor during Opposition

Acquisition type: Lucky imaging

This is a transit of Io across Jupiter, captured with a small refractor (ZenithStar 61ii) and a Barlow (TeleVue Powermate 5x), captured during opposition. This is about an hour of the transit event.

For each panel:

Capture about 3 minutes of 240p video at ~100 FPS and high gain (10ms frames, gain ~500)
Stack top 10% of frames with 3x drizzle
Wavelet sharpening
Mild AI touchup
Photoshop crop, color enhancement, and smart sharpening

In my image train, Jupiter is about 100 pixels wide prior to processing. The effective focal length is about 1800mm, at approximately f/30.

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.
