Hello Stan,
I have a 12" LX200GPS and I would never consider using it as a
portable scope. Even the tripod is a monster and I am not a little
guy. One reason the scope is so heavy is that the OTA is not just the
OTA but the whole scope, forks, base, mechanical gears and
electronics. Joe Goss usually brings a 14" Celestron CGE telescope to
star parties and I was always amazed he could set that up quickly by
himself. But he has a German equatorial mount for it and the OTA is
indeed a single and separate item. Just as with your telescope that
would break down into pieces. Imagine trying to move you whole
telescope, OTA and drive assembly as one unit. The LX200 does not
break down.
When I put my LX200 on the permanent mount it was all I could do to
lift and set it on the wedge. I would not want to do that more than
once. The biggest problem is not the weight, but how to grip and
carry the unit. Despite coming with a tripod, I would not classify
the 12" LX200 as a portable telescope. Certainly there are people
who do use it and large fork mounted SCT telescopes in a portable
mode, but not recommended for mere mortals. My 13.1" DOB is very each
to move, setup and take down because it all comes apart.
BTW, there are some special handles available to replace those on the
forks that make handling the scope easier, still not easy, however.
Those handles are not cheap but do seem to help. They are $130 for 2
