Re: Scope balancing question

Hi Paul,toggle quoted messageShow quoted text
The Traveler is light weight and there is a certain amount of inherent stiffness
in the 600E... more so than was in my AP400 mount. But I am not certain if you
are not experiencing a problem because I do not understand the following:
I'm not clear which axis your son had trouble turning. Did he try and rotate
the DEC axis by turning the counterweight as though it was a steering wheel (so
as to revolve the telescope in a circle around the DEC axis, as you stated) or
did he grasp the counterweight and pull or push on the counterweight shaft (so
as to move the mount about the RA axis)? And was the traveler seated on the
mount at the time (I assume so... but do not know for sure).
If he had difficulty turning it about the DEC axis, you probably do not have a
problem. If he had trouble revolving around the RA axis, especially if the
Traveler was seated opposite the weights, the clutch plates are too tight. They
are easy to adjust... let us know if that is the case.

Traveler) and the bearings on both axes of the 600 are really quite stiff(much,
much more so than on my Great Polaris). Even with the clutches fullyaxis.
I had my ten year old son try to rotate the dec axis boy simply turning thean
exact balance. I can move the 9 lb counterweight an inch or so up or down thethe
stiffness of the bearings.one
inch on counterweight position be considered sufficiently precise? I'm alsothem),
and I'm wondering if this is due to poor balancing.
