Re: The Awesome 1200
I had a chance to see Ray Gralak's new goto 1200 mount this past Saturdaytoggle quoted messageShow quoted text
night. Most impressive in some respects, a little disappointing in
others. Supporting a small 5-inch f/8 refractor, why did it have a high
frequency dampening problem? I suspect the thin walled, hollow pier to be
the culprit. I have the same problem with my own QMD 1200, vintage 1997.
Anyone have any thougths on fixing this problem? Not that the mount isn't
stiff in the wind, but the vibration is noticeable during any focus
adjustment or slight tap on the telescope tube assembly. Clutch knobs
would also end up behind motor housings. I guess with goto this doesn't
matter much. Why such a big microphone for speech recognition? Wouldn't
a wireless mic be awesome?
On the positive side, the tracking and pointing accuracy were top notch.
Ray had no problem finding and centering objects. Two minute unassisted
exposures yielded sharp, round stars. Great improvements in the DC servo
motors vs. the DC steppers. I have always seen stepper bounce in my QMD,
none noticed here. The machine work is excellent, but the paint chips too
And here's the latest from Ray using the new 1200. About as good as it
