I agree with bart, looks like progress was not there, It is due to dock today at around 5.30, so maybe it was not that near the iss last night. Like dave said starry night was wrong

Well lads, I just had to try this last night, I can tell you its not easy to get the scope following the ISS, you get the positioning or timing even a tiny bit wrong and you wont see it, it was only on the very end of the crossing did I manage to get it in the scope, by then it was small and very faint BUT IT DID HAVE A DEFINITE SHAPE TO IT :P
I'd say when I say it it was 1/2 the size of saturns disk ??
If its clear tonight I'll be much more prepared, as it took a small while to get it right.

A word of warning, as you're not watching the mount when doing this, its very easy to run the camera into the mount when following the ISS, I did a lot of "fake" transits and watched what the mount did and if the ISS is particularly high in the sky, you can cause alot of motor damage by running the tube into the mount..

Hi Dave, what magnification were you using?

I have sucessfully followed it and other satelites with the Dob at low magnification, no risk of motor damage here! :D
However it is so bright at the low magnification and the unavoidable shake from manual tracking, that trying to pick out any detail is very difficult. It is just possible to see that it is more than a circular bolb of light with just a hint of shape to it. Must try tonight (if clear :roll: ) as the brighter skies at this time of year might help reduce the glare.
You can practice on passing aircraft. Getting it in the eyepiece to start with is the most difficult part. The telrad is a great help for this.

I was using a 26mm eyepiece which gives me a magnification of ~115.
The weather wasnt good for the ISS the last few nights, maybe tonight will be the one.
