[ATMoB-discuss] ISS/Atlantis

[John Boudreau]

Thanks Paul, that's what I was afraid of--- I seemed to recall Bruce mentioning that balance was critical on the club's GT1100 in order to prevent stalling.

I could be interesting if a motor upgrade can fix that, but as of yet I haven't found anything on the web indicating that the GT1100 can track satellites with The Sky 6. on the web, I'm only finding such references for the Paramount ME...

...but I seem to recall that tracking satellites was included in the early GT11000 ads in S&T in the late 90's.

  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.
