Can I see ISS from Sydney-Australia?

Hi

Is it possible to see the International Space Station from Sydney/Australia
with an 250 mm Dobsonian telescope of type as shown in the following link
(http://www.bintel.com.au/BT252.html) ?

Thanks

Go to http://www.heavens-above.com/ and check the time of the passes of
the ISS over your head.
You can surely see the ISS with your scope, but the main problem will be
to be able to follow it

You can *see* it with the naked eye; it's as bright as Alpha Centauri.

The ISS appears about forty arc-seconds across, so with that telescope
and a 9mm eyepiece it would look about twice the size of the Full
Moon; you'd probably be able to see the solar panels.

However, the ISS moves fast enough across the sky that I suspect it
would be extremely difficult to move the telescope smoothly and
quickly enough to track it within the field of the eyepiece (which is
a region of sky about the size of a thumbnail held at arm's length).
The observations I've seen of ISS have been using telescopes with
quite elaborate computer-controlled mountings.

It's not impossible, but I'd be very impressed if you could do it;
you get one ISS pass a night to practice on and they only last a
couple of minutes. I'd start by finding a good prediction of where
the ISS would be and star-hopping to that region, then wait for the
station to appear (it'll only be in the field for a few seconds) and
desperately try to follow it. You could also practice on reasonably
low-flying planes or moderately distant birds.

I watched it last night from Newcastle with naked eye/binoculars, using
flyover data from the heavens-above website...... tonights will be
better again, then Tuesdays should be really good...... good luck!
