I notice that you suggest GSC1.1 for use with Pinpoint. Why 1.1? What about GSC_ACT or GSC1.2? Will these work? And what about UCAC1, UCAC2 or USNO_A2.0? Of all these, which yields best plate-solve results (speed and accuracy)?

I'm trying to decide if I need the whole package with GSC1.1 data, or whether or not I already have something that will work well...

Thanks!
