[ATMoB-discuss] ISS/Atlantis

[Paul A. Valleli]

John,All

I don't think the GT1100 is powerful enough to move
the C14 fast enough and stay on course - I measured
15 degees in 10 seconds last week, using Al Takeda's
and Mike Schexnaydre's images which show the Dipper
in the FOV .  That's 1.5 deg. per sec. It would have
been faster than that when overhead. 

If Bruce Berger can get the motor/controller
 upgrades installed from SBIG, It should do it.

  >I'm not sure if our club's GT1100 mount can do
  it, but I know Software Bisque's 'The Sky 6' can
  be used to make a Paramount ME track satellites
  pretty accurately. It certainly would be something
  to look into. If the GT1100 can do it, the club
  may already have most of the equipment to image
  the ISS with surprising results.
