Ok,

a couple of questions,

Where is Guide9 installed?  i.e C:\guide9 or somewhere else.

Is the UCAC4 on the same drive as where guide is installed?

Hi John, Dennis,

Did everything you mentioned in your posts but still unable to see and UCAC4 data.

Under Extras\Toggle user data sets UCAC4 is listed and I can select it (indicated by an asterisk). In the resulting window I have checked On and Label and Show at 0 - 180 (which I presume is the size of the display in degrees in which UCAC4 data will be displayed).

Perhaps I am looking in the wrong place. If, for example, I right click on a star and then select More info what should I see?

I have experimented with CMC14 and UCAC3 and can get that data displayed. Shows as a block of IDs more or less in the centre of the screen and I can zoom in on a particular star to see its CMC14 or UCAC3 data. Does UCAC4 data display in the same way?

Regards
