Thanks Trevor - I downloaded PHD the other night (something else to learn

so I'll have a look at how it works in there. When the skies clear I'll try to complete the CCD challenge

and try some longer subs - see how close it's getting.
If I end up getting an Autoguider I guess I'll have to get to grips with something like PHD anyway though so maybe I have a play with it now anyway.
The alignment option in Backyard EOS is always greyed out for me - I'm assuming that's because it's either a, a trial copy or b, it knows my camera has no live view and that's what it uses ?
Cheers,
