Jim,
When you get all set up, you will end up with a harness of bundled cables,
wrapped up in split coil sleeves, or something. If you do remove the CP3, I
would put a small plastic bag (or

Hi Joseph,
Definitely the Hand Paddle comes in, and I was given the same advice
by someone at AP with respect to the CP3.
I guess there are two approaches. One school seems to argue that a

Re: AP1200 on Permanent Pier sans Observatory
Hi,
One thing that Marj once recommended to me was to at least remove the CP3
controller, and bring it inside. The concern was for condensation getting into
the electronics, causing corrosion.

Re: Pier design
Hi Niels,
Yes the amplitude will be slightly less for an impact, but will be
the same for a force applied. A force deflection of the mount
depends on the stiffness of the pier tube, not the mass.

Re: AP1200 on Permanent Pier sans Observatory
There is a often bit of misunderstanding about condensation etc. and equipment. The military has this sort of problem and uses environmental covers and spray treatments for a wide range of equipment

Re: Pier design
My MI-250 portable pier has wood discs wedged tightly into each end (about
4") and this acts as dampeners and does a good job, without increasing
weight.

Re: Pier design
Hi Don,
OK.
But don't you agree that the amplitude will be smaller when the mass
is increased? (for same impact)
Best regards,
Niels

Re: AP1200 on Permanent Pier sans Observatory
I still like the one that looks like an outhouse, including the half moon on
the door. Just open the door and it rolls away from the scope. Should fit
right in behind any modern home

The only problem is welding the top, which then commits you to the

Here are three panoramas I put together that try to show the conference in a

Yes, condensation is a issue. There are many approaches. I suggest
that you make the cover completely air tight on all sides and the
