Hi Paul,
That sounds like it would be an excellent setup for variable star observing. Some BAA observers have started to use Muniwin for variable star photometry as it produces output files in the format for upload into the BAA VSS database.

As well as looking at the VSS website it is worth dropping Roger an email line if you would like to start variable star observing. The section is very active and we are always keen for new members. Of course this forum is also ideal for any questions as there are other people can look at the answers.
Best wishes,
Andy (BAA VSS Database Secretary)
