First Jupiter of the season 12/6/2023 MST

Revision title: Processed Image

Acquisition type: Lucky imaging

I finally got my act together and rolled out the 10" Newtonian to image Jupiter. As is usually the case, the seeing was mediocre despite Jupiter's high altitude here in Parker. I took 19 videos that contained 8920 frames in total of which 5% (446) were used in stacking. The original image posted is the WinJupos derotated result which is disappointingly fuzzy. I used automatic frame alignment and, thinking the outcome was too blurry, repeated the frame alignment with the manual approach. That didn't help, so I guess the seeing was the problem. It's no secret that the seeing in Denver is usually dicey owing to atmospheric disturbances caused by the mountains to the west as the prevailing westerly winds blow over them before heading over the city. I was once told by those in the know that the 20" Clark refractor housed in the Chamberlin Observatory on the campus of the University of Denver turned out to be less useful as a research instrument than hoped after it saw first light in 1894 because the seeing rarely cooperated. Anyway, it's always worth a try to go after Jupiter because every now and then you get lucky with the seeing. This time, not so much, but I still thought the result was worth posting because Io is casting such a nice shadow. The workflow in the processing that I followed was so full of dead ends and restarts that I really have no idea how to reproduce what I did. Bad scientist!

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.
