Jupiter Observed at opposition.
Hughie is playing with me. For the first time in ages the sky wasn't clouded over, come sunset I set the telescope out side, hoping to catch the shadow transit of Io on the night of Jupiters opposition. But no, the clouds came over as soon as I had put Smallest One to bed. Fortunately there was a tiny window of clear sky and I got these two shots of Jupiter as Io cleared it (click to enlarge). The images are composites, I shot Jupiter at low exposure time, then cranked up the exposure to image the moons. I then pasted Jupiter from the low exposure onto the over exposed Jupiter of the satellite image. (Each image is a stack of around 50 frames out of 60 in Registax).
You can see quite a bit of detail in the enlarged images, which is pretty amazing given this is taken with an old webcam on a 4" unguided Newtonian. The top image shows some really nice cloud detail (when you click on it and get the enlarged view).I didn't get to see the new "son of the Great Red Spot", but new Hubble images have been released of it.
