Jupiter and Io on May 1, 2018 (JDJ)

Jupiter and Io on May 1, 2018

Captured this image of Jupiter on the first night of average seeing (poor seeing seems to be the status quo) in the past few months. Images were still on the soft side, but much better than my attempts during poor seeing. Still holding out hope for some above average seeing close to opposition next week. Jupiter cleared the trees just as Io was completing a transit. Seeing wasn't quite good enough to make out Io against the background of Jupiter, but it was nicely visible once as it crossed the edge of Jupiter's disc.

Imaged with a C8 Evo, custom Siebert 2x barlow, ZWO ADC, and ZWO ASI224MC. Image capture using Firecapture. Wavelet sharpening in Registax.

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.
