Not great seeing after all the storms and high wind but something. Io to the left, about to do a shadow transit later.

Jupiter 2022-08-31

Decent seeing for here and quite a lot of detail. Still need better collimation.

Not as sharp as many others produce but still a lot of detail visible. A few dark spots/barges to the north, white ovals beneath the GRS and some nice cloud features. More detail in the NEB than I normally see and interesting to see how thin the SEB is at the moment as it starts to wrap around the GRS. Never captured the North Temperate Belt before (the thin one above the NEB).

Jupiter & Saturn 2022-08-06

First of the season. First of the season. Saturn still low and murky. Jupiter’s extra altitude makes it much easier this year.

Callisto and Ganymede shadow transits

2021-12-08T09:25:23+00:006 October 2021|Jupiter, News|

Poor seeing so not much detail visible on Jupiter so concentrated on the shadow transits. Seeing comes in and out through the session. 13 frames in an animation. Satellite visible is Ganymede. Callisto is much further out and so the Ganymede shadow catches up with that of Callisto.

Jupiter colour / infrared

2019-06-26T09:01:41+00:0025 June 2019|Jupiter, News|

Jupiter is so low that only half of the telescope could see over the lip of the dome, so effectively only a 125mm telescope – not 250mm! Surprised I got anything at all at this altitude.

Not much detail visible but the infrared version is much sharper, cutting through the atmospheric turbulence better, and shows the Great Red Spot as white. The SEB is clearly changing and shows white in the colour image. Is this part of the unravelling of the GRS that is reportedly happening?
