Hello Bob

Yes, I realise all the facilities within Guide (I have been using it since
Guide-2). Guide shows me exactly where comets are (as you know).

I use ACP to drive the scope for imaging purposes. ACP requires elements for
its script files. Hence the problem. I have managed to download one set but
they actually failed the format test (ACP plan checker!) so I couldn't use them.
Another comet set downloaded but ACP told me that the comet (shown in Guide at

>50 deg altitude) was below the horizon. I can't fix problems like those.

regards

Lawrence
