I would like to try the pendulum counterweight idea. For those that

have used this, what is a good weight to try?



Larry Phillips

#32830 Apr 30, 2007

Larry,



If you are going to try this, I suggest using a "nylon" rope. Ranier's

looks like a cotton fibre rope in the photo, and I image it will turn into a

"noose" as soon as it absorbs some dew. Then it will snag on the setting

circle, and choke. A nylon rope should slip through easier.



The other thing that bothers me a bit is Ranier's rope is wrapped around

the RA setting circle. I fear that after a while it is going to damage the

numeric engravings. A clear plastic collar loosely set around the setting

circle would protect against any "rope burns" over time.

Hi Larry,



I would have expected Ranier to chime in by now - maybe he is away from

home. Suggest you email Ranier directly, and he can advise you on how much of

a pendulum weight he uses and what his scope and C-weights are.



He has an interesting approach for another reason.

One idea might have been to use a spring or bungee cord. This would be bad

since springs increase in force in proportion to how much they have been

pulled. The pendulum approach produces a constant force, independent of

distance to where the telescope is pointing in RA.

I've been using this system for over a year. I use a cord, not nylon. It is very

gentle on the system and does not unravel, even though I live in a humid,

sea-side environment. I operate my system remotely from the house and let

scripting software drive it all night while I sleep. It's a great relief never

having to worry about manually shifting the counterweights. In fact, the very

idea of shifting the counterweights seems like a relic from the past.

I was thinking about making a pendulum counterweight for my G11.

I searched the archives and found a reference to Greg Crawford's site

where there was a picture of the counterweight hanging from the RA

shaft to allow imaging from either side of the meridian without moving

the main counterweights. Unfortunately his site seem to down and/or

gone. Does someone else have a picture of this kind of setup to share?



Thanks,

Eric

Well I can ping www.nelsonbay.com just fine. But the photo won't load in any

of he 3 browsers I tried.



I can also ping www.portal.newlsonbay.com (the host I get redirected to).

Hi all,

Greg sent me the pic offlist (thanks again Greg!) and I tried it out

last night. I used a 500 ml bottle of water filled with sand from the

neighbours play structure, an old ps2 7' extension cable, a 3"x1"

strip of plastic cutout from a crazy carpet (for those unaccustomed to

snow a crazy carpet is a very fast light weight sliding apparatus for

the more adventurous tobogganer) and of course what no project can go

without: duct tape.



It worked great.
