Hi Geoff,
Dave Kriege, co-author of "
The Dobsonian Telescope" and founder and
owner of
Obsession Telescopes, has told me much the same. Well designed
Dobs are simply not a matter of aesthetics and are instead based on sound
engineering principles backed by solid physics. On some designs, the
engineering assumption was made that the mount would be relatively level
with respect local gravity, otherwise its performance and handling could
be compromised. In these instances, motorised slew and track systems are
a preferred option over platforms, as the mount then does not need to be
tilted.
