Hi Dwight-
I'm a bit confused by this spur drive claim and I
suspect that's what at play here is the drive train between the stepper and the
worm. Not having seen an EQ-6 in the flesh I can't say that's the case but
that's what Synta seems to do. Heck, Takahashi and others have used spurs to
couple the drives to worms to good effect (as have our engineers in linear
motion applications that exhibit excellent sub-micron pointing registration
over a 48" panel on an X-Y table- and that table weighs some 200# and cycles
24/7/365 for years).
I guess I'm going to have to get one of these
mounts and see for myself....
Regards,
Bill Dean

I
just learned that this mount is a spur gear mount and not a worm gear driven
mount if that is true you are going to drive yourself crazy trying to guide
with this puppy. I would keep my distance from this mount.
Based
on the above to protect your sanity "I take it you don't have a Auto guider
like the ST-4" A spur gear mount also known as the Random periodic error drive
you crazy method of guiding. Celestron used to use this kind of drive system
for there SCT's years ago. Changing to a byers gear and worm was a turn for
the better as far as Celestron is concerned. That is what I have in my Ultima
9.25 SCT
Well
it looks like your going to choose between the GM-8, the Tak EM-10 or the
Vixen DX. I have a friend who has a Tak EM-10 mount and likes it very much
this I would suggest, are you absolutely certain you cannot get the G11 for a
better price. You don't need the goto version the standard G11 is still
available.
Good luck
