Jupiter 12 Apr 2019 - first 8 min WinJ composite

Jupiter on the morning of Sat 13 April (Canberra time).

It was going to be my main collimation session following first SCT optics cleaning in six years of use. Set my alarm for 2.30 am (much easier to do on the weekend) and used on screen preview to fine tune secondary alignment, adjusting sharpness with zero-shift focuser. I had removed corrector plate for isopropyl alcohol and distilled water treatment as it had quite a lot of pollen / water spots on it.. wanted to make sure all stains are removed in a controlled environment.

Seeing was fair to good early on but crashed one hour before sunrise. Luckily I did have enough time to complete the task before the plate started to fog up (conditions are becoming more humid now). Although strong jet stream was prevalent, I did manage to record two short lived periods of relative stillness.. here's the first one centred on 17:10 UTC. Descent amount of detail can be seen with South Polar Red Spot approaching CM.

WinJUPOS derotation of four 600 frame stacks, covering period between 3:06:25 and 3:14:11 am local time. FireCapture v2.6, individual video clips 80 second in duration.

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.
