Re: [APML] Calibrating STV axes independently

["westergren" <westergren@netzero.net>]

Joseph,
My STV has so many features packed into it, in ROM (or PROM) that originally
SBIG was running out of room to include the independant axis calibration.
They figured out how to include it about a year after the STV became
available.  The upgrade to the ROM program (downloadable via the internet)
is also a feature that is not available to the ST-4.

I have experience with both the ST-4 and STV.  They both guide to give great
astrophotography (pin point stars), but the extra features of the STV make
it a remarkable and much more useful camera/autoguider.  Is it worth the
extra $?  It is if you have the extra $.
