The second image is magic, the moon is like a flash light in the sky, but can I ask, how is Jupiter trailed ?


It's Antares Dave, look at the line above the image! :oops:

Dave,

The moon is also trailed, but because its bigger its not as noticeable just looks like a distorted sphere. (look more critically at the overall moon and you'll see it). Fixed tripod and long exposure, no tracking.

Seanie,
Its always a tradeoff between how much background detail to show and how overexposed the moon is in a single shot exposure like this. I did bracket all the way up and down and the one shown seemed to be the best compromise. It takes 1/125 of a second to get the best moon detail, yet it takes about 8 seconds to get a half decent background at this time of night - so it really is a tradeoff.

I didn't realise that it was a "long" exposure.
I still think it is a great image .

Its interesting that you cought the 4 moons of Jupiter, its tempting to think that you might be able to see them with the naked eye, although I've never heard of anyone who did.

Dave,

OK maybe "long" is the wrong term here, but in terms of lunar photography 5 seconds is very long - 625 times too long in fact.
