In the methane image, the extension of the north polar veil at these latitudes is remarkable. In UV the GMR is noticeably absorbent (dark).

Comparison between the Chroma methane filter (left) and the Baader (right).

I managed to record the double transit, despite the poor seeing and the planet low on the eastern horizon.

I compared approx. 10′-12′ of data gathered with the ASI290MM (on the left, with slightly cooler colors) and the ASI462MC. The seeing conditions were more than fair, and the processing is very similar in both cases.

This comparison may show how small the gap between monochrome and next-generation color sensors is today.

2021 apparition was characterized by the EZ (equatorial zone) showing an exceptionally dark orange colour.

Here we see the planet together with its largest satellite, Ganymede. The satellite was pasted separately and the image is not oriented.
