Hi Folks:

 

I don't post a lot of photos here, I don't feel the calibre of mine are quite up-to-speed (yet) with some of the absolutely fantastic images I see here.

After getting a nice collimation on Thursday night into Friday morning last, we set sights on the planets, lowish in the south. When we turned to Jupiter, I thought we had caught the Red Spot for a nice change of luck, but it turned out to be a shadow transit of Ganymede. In 45 years of observing, I've never watched a shadow transit. When my trusty assistant said, "is that the moon to it's left?", the answer turned out to be "yes".

The seeing was not terribly good (maybe 2.5/5) and the wind was howling at gusts up to 40 km/h, but I ran a few series of images. The result is attached here. I'm not super happy with the disk of Jupiter, but I am happy with the distinct ability to discern the moon and it's shadow. Small victories, I guess.

Taken with a 12" Meade LX200GPS and a ZWO ASI290MC. I did not use the ADC or any filtration.

As always, criticisms, comments, and advice are always welcomed.
