2021-11-17 First Derotated Jupiter

Acquisition type: Lucky imaging

Some new equipment was necessary after my 2-inch Celestron SCT Diagonal Broke when I had an impact on my scope as I was moving it around the house.

New 2-inch Celestron SCT Diagonal, a redo of collimation, and a new camera.

I got a Player-One Neptune-C (IMX178 chip) from agenaastro.com because my ASI120mc was acting funky ever since Windows 10 and usb 3.0 ports. Seem the original ASI120MC USB 2.0 was a non compliant usb interface, and I would get lock ups. i decided on a 178 based sensor so that I would have a larger field of view due to my alt-az mount and so I could also dabble in DSO photography.

The seeing was terrible today with high jet stream winds, but I wanted to test out my redone collimation. I think I need do a fine collimation but I am waiting on a calm day to do a star test.

I also tried to do a winjupos derotation.

4 1 minute subs at 80 FPS (way better than the 20s to 30s that my ASI120 would get if it wasn't locking up), PIPP to reduce down to 1200 images for each subs, Autostackert down to 25 percent (terrible seeing), registrax for reglet sharpening, and combined together using WinJupos Derotation.

Can't wait to test this out in better seeing if I get the chance. Jupiter will soon be too low and my backyard horizons are blocked with trees, when that happens I will go onto DSOs until next year's planetary seasons.

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.
