Re: [APML] Drift alignment problem - wedge mounted scope

[steve banbury <banburys@sonic.net>]

Hi Bradley---I have the same problem with clouds moving in here too.
If you get a long enough clear spell, it would be interesting to see if 
the drift
is repeatable--i.e. if set up with no or low drift at +10 deg Dec,  go 
down to
-10 deg and measure but do not correct the drift---then return
to +10 deg.  Is the drift still zero?

I have had a tripod leg sink into soft dirt slightly, and have had one 
of the
telescoping legs compress despite tightning the the locks as hard as I 
could.
