Jupiter with moons Ganymede (top) and Io (bottom).
|Apparent size:||47.4 arc-sec.|
|Diameter:||142,984 km (about 11.2 Earths).|
|Distance:||4.16 AU (about 34.6 light minutes).|
|Exposure:||0.377053 sec – best 125 frames stacked from 500 frame video.|
My first effort at Jupiter with the new combination of camera and 2x image amplifier.
All four of the Galilean moons were captured in the original image but Europa and Callisto were further out and didn’t survive the crop. Both Ganymede and Io needed to be digitally brightened.
At least with the Moon nearly full, planetary imaging is still possible. Our world has been unrecognisable over the last few months and getting outside with the telescope is a calming influence, even under the suburban skies to which I am still limited.
I see covid creating havoc in my home country, England, where I fear the worst as they rush to open up prematurely. I see massive numbers of infections and deaths in countries where stupid leaders have not taken the virus seriously. I see unfolding world disaster.
It’s all beyond my comprehension.
If China – with a massive population of 1.4 billion – can limit its infections to “only” 85,000 (most of them in just one province), how can America – with a population of “only” 330 million – permit nearly 3 million infections (so far)?
Land of the free? In God we trust? Hail to the Chief……
It hurts too much to even think about it all.
Australia now has a second wave going on down in Melbourne. Some of us can only put our heads in a bucket of sand while the health professionals do their best. I’m going to go and polish my telescope and dream of clear night skies ahead…..
