Europa Transiting Jupiter on June 15, 2019 (JDJ)

Europa Transiting Jupiter on June 15, 2019

Acquisition type: Lucky imaging

Observed and imaged Europa's transit of Jupiter on the night of June 14/15, 2019. This image was taken near the end of the transit with Europa at the edge of Jupiter's disk while it's shadow was still fully on the planet. As a bonus, the great red spot was just coming into view on the opposite limb of Jupiter. Conditions were average at best with a few moments of decent seeing (always a good sign when the moons can be clearly seen to aid focusing) but intermittent high clouds that messed with capture times throughout the session.

Imaged with a C8 Evo, custom Siebert 2x barlow, ZWO ADC, Baader UV-IR filter, and ZWO ASI224MC. This imaging train gives me ~F/20. Image capture using Firecapture. Stacking in AutoStakkert3. Color balancing and Wavelet sharpening in Registax6. This images is a stack of the best 25% of ~25,000 frames captured over 180 seconds at 150 FPS.

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.
