Jupiter 20251026
A big reminder that 04:00 is much better than 05:00 because the cloud rolled in at 05:00 edt this morning. Ick!
This was the best of 19 imaging runs, using the best 5% of 27K frames, each at 3ms. Jupiter was a quite decent altitude of 58 degrees.
The Great Red Spot is easily seen in the processed version and even showed up in the unprocessed version… seeing and transparency were both “average”, which is much better than normal, which is “poor”.
Note the small white oval above the Great Red Spot, in the dark northern band.
Oh.. and it was -5C this morning here 🙁
Wait.. there is more!
This is the First Light using my new CH4 methane band filter.
I had to remove the UV/IR cut filter as they did not stack one atop the other, and I am not sure if things would have worked out in any event.
I was expecting a little more exposure but was surprised that it was 100X more exposure needed! From 3ms to 300ms!
I processed at the best 5%, 10%, 50%, 75% and 100% of approx 400 frames and settled on 75% as the best results.
The Great Red Spot appear bright in the lower right.
There were high clouds at the time of this imaging run as well. I hope to try again under nocloud skies with maybe 180 seconds in stead of 120, raising the frames from 400 to 600.
Last is the animated .GIF of the mornings session, from 08:15UTC to 10:05UTC, including the methane filter images.
