Callisto and Ganymede shadow transits

2021-10-06T10:25:16+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

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?

It’s amazing the difference good seeing and a clean corrector plate makes (Baader Wonder Fluid!). Again, low jetstream overhead. Definitely my best Jupiter so far.

Poor seeing again. Different x2 barlow which gave a much larger image than the other x2 barlow for some reason! Too large probably as more noise was visible. Re-collimated the Mak earlier in the evening as it was a bit out. Think it has actually made a difference but will only be able to tell properly with better seeing.
