Thanks for the tutorial Jase it will be a great help
Whilst on the subject of guidescopes we use a 70x500 at the moment now we need more focal length to help with guidestars.
We have read that ideally a guidescope should have a closer fl to the imaging scope. Is that correct? Wer'e contemplating a 1000fl GS do you think that would help with guiding more accurately? We use PHD by the way
Thanks again
