Hi Ulrich,

Errrmmm... yes, it's now going to the double star A250.
(As in Aitken 250.)

There really should be no cause for ambiguity here:
-oA250,40 should cause Guide to find azimuth 250, altitude
40; -oA250 should cause it to find the double star A250.
I'll fix this. I think an update will be needed in the next
few days anyway, to accommodate a change in the nomenclature
system for UCAC3.
