SV: [Losmandy_users] Pier fo G11?

Hi folks,



I will be getting a pier soon for my G11 mount. It will be 48" high

and will hold a TEC140 refractor (22lbs). There are several pier

mfgrs (Astro Sky, LeSeuer) who offer a pier made for the G11. It is

6" diamater and either aluminum (AstroSky) or steel.



I was wondering if a 48" high 6" diameter pier will be "solid"

enough for this setup, in order to minimize vibrations for visual

work. I could opt for a larger 8" pier but it is a significant jump

in cost and I don't know if the benefit would be noticeable at the

eyepiece. I could fill the 6" pier with sand to help.



Any feedback out there? What have people found with their 6" pier?



Thanks in advance.



Regards,

Rob

Rob, I have a 6" pier from LeSeuer (highly recommended -- great

service). The specification for the 48" pier is that it'll support in

excess of 1000lb without a problem. I have no vibration problems with

this pier with 50 lbs of scope equipment on a G11/Gemini. Even for

ccd work.



IMHO, 6" should be plenty for a 22lb visual load :)



Regards,



-Paul

Inspiers me for my first comment. Received a brand new G11 3 days ago. It is with Escap motors and I already had the FS2 controller. First thing I did was to bore 4 vertical holes in the G11-s ground plate - for 4 pcs of 8x50mm (inhex) screws. They hide well below the surface and aside of the small unnessecary under-plate. (1/2mm clearance at each side :-) ). Those screws have been screwed into my flat surface mounting plate. Hence - I feel the g11 can be used on any flat surface - not needing a special designed mount or pier.

Traded the dreaded EQ6 for the G11 - and switched yahoogroup accordingly... (They were not happy there at EQ6 eventually - entertainig though to follow it..... We had extremely bad PE and no one seemed to find a cure.)



All right: First impression of my G11 ( have had GP, GP-DX, SX90, GP, EQ6, and LX200 with various contolling systems).

1. Polar is very friendly! Have a concrete pier - but to start I had to use the polar finder - it was very very easy - LED light included.

2. Backlash in the AZ adjustment... (have read about that...)

3. Surprice for me - it is a friction mount, I was not aware.. Nice - just slide to a star (and make it "ref" to the FS2 controller)

4. Not that heavy - the EQ6 piece of was much heavier.
