Using the data acquired on 2019-09-02, I put together this nice animation.






It wasn’t a surprise that I caught Jupiter, for I was cooling the telescope for quite a while before sunset, but it was a nice surprise to see Europa’s shadow departing — reminding me of the good old times of this year’s Jupiter season when the planet was visible for several hours (though still as low as it can get, above the city’s turbulent air). HEQ5, N250/1200, TSO ADC, ASI 224MC (cooled), home observatory, mountpusher Photo taken at 19:21 local time with the Sun just behind the hills to the west of the city.
HEQ5, N250/1200, TSO ADC, ASI 224MC (cooled), home observatory, mountpusher very bad seeing conditions
The blue sky is what it is: my passion. That I start to observ early in the evening to catch something. Anything. So here it is: Jupiter on the still bright sky. HEQ5, N250/1200, TSO ADC, ASI 224MC (cooled), home observatory, mountpusher
The setup was the usual, ASI 224MC, TSO ADC, N250/1200, HEQ5, and the seeing had its good moments, but there were some clouds or fog.

During this morning, Ganymede played hide and seek, emerging from Jupiter’s shadow, just to disappear again, behind Jupiter’s limb. I used my usual planetary setup, ASI 224MC, TS Optics ADC, Barlow, N 250/1200, HEQ5 installed in my balconic-balcanic improvised observatory. The seeing was, this time, good to very good, with Saturn’s Cassini gap visible on the live view images, and Jupiter GRS also obvious on the live view. It’s mostly not the case, I must add. The moons are Io, Ganymede and Europa. Ganymede was part of the original recording (it was in the ROI selected for the planet), while Io and Europa are composited onto the image.
