Jupiter and Io composite image (data from 6 September 2021)

Acquisition type: Lucky imaging

The data for this composite image of Jupiter was acquired on the evening of September 6th earlier this year. Seeing was reasonably good, and the planet was roughly 36 degrees above the horizon at the time of capture. I used an ADC, along with a QHY 5iii 178c planetary camera for the image (frame rate of 40 frames / s). I stacked the best 40% of frames from 5 videos (about 6600 frames total) to compile the image. A separate exposure was used for Io, shown here just to the right. I was not able to resolve any details on Io -- I will have to work on this further!

It took me a while to process this data set, but I was relatively happy with how it turned out. I was much more patient with collimation, adjustment of the ADC, and allowing the telescope tube to cool down prior to imaging, which helped improve the data quality. Using a higher gain with the QHY camera (and a better solid-state hard drive) also allowed me to use a higher frame rate. I believe this camera should be capable of even faster data transfer than than 40 fps, but I may need to do some further optimization with the USB settings.

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.
