ASI462MC first light - Ganymede and Jupiter

Revision title: Reprocessed Card

Acquisition type: Lucky imaging

Up until now I had always used a ZWO ASI120MM and separate color filters for planets, but I wanted to try out a color camera for easier animations and derotation now that the planets were finally starting to rise higher in the sky again. So I ordered a ZWO ASI462MC color camera: it uses one of the newer generation Sony IMX492 sensors with very low read noise and excellent sensitivity in the near-Infrared spectrum.

Finding focus took a lot of trial and error. I had to find the correct combination of extension tubes, adapters, accessories and primary mirror position. Luckily, the Moon was up and that made everything so much easier. The camera train was: 30 mm 2" extension tube > 2" to 1.25" adapter > 3X barlow > L-2 filter > nosepiece > ASI462MC

I was very happy to see some surface detail on Ganymede! Probably over-sharpened the stack a little bit in all my excitement, as this image is just a simple 30 second video. My gain and exposure time would technically allow for more than 200 FPS, but my ROI was set too large for the USB2 connection. So left about 20 of those 30 seconds unused. Definitely something I could work on next time.

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.
