On 15th August, there was a lot of moon activity near Jupiter.

It started with Callisto crossing the disc and casting a shadow near the GRS. Shortly afterwards Ganymede and Europa cross in pairs until Ganymede eclipses Europa hiding it from our view, but still casting double shadows! The time span of this sequence is ~4 hours.

C9.25 EdgeHD at f22, ASI290MM, Astronomik LRGB IIc, 1x30s RGB, Adelaide.

Thrilled to have resolved moon surface details for the first time too!

Love how the series of images seems to draw ones attention less on Jupiter and more onto the Moons. This is good .. real good :thumbsup:

Really nice set of images of the transits, very good detail captured, with albedo features on Ganymede a bonus.

Thanks Hans and Jeff! Was fortunate to have some very brief windows of good seeing in between all the clouds!

Brad,
Is that with a powermate or 2x barlow?
Excellent work !

Thank you :)



I was using a Bintel 2.5x 3-element barlow. It's more like ~2.2x, works pretty well with my sampling.
