Sinking mount legs


Bill Faatz
 

OK, enough of the teflon washer. I wonder if anyone has a solution to
this problem. Over the course of an evening's observing, I notice
that the front leg of my G11 starts sinking into the dirt (according
to
the bubble level). This is the one directly below the dec
counterweights,
so it sees the bulk of the weight distribution. The other legs are
probably wandering too. This causes my initial alignment to wander
off, and consequently makes it harder to locate objects with the
setting circles. The ground out here in northern California where I
observe is
largely adobe. Anyway, I wonder if there is some aftermarket product
like a shoe that would slip into or over the ends of the existing
legs
and help distribute the weight over a larger area. Another observer
with a G11 uses old TV Guide mags under the legs, but I was thinking
of a more elegant solution.

Hi Bill,

There are small ground platforms (usually metal) available that are
used in the world of surveying. These often have small spikes on
their underside and are stamped firmly into the ground. They are
used for supporting the tripod feet of theodolites and leveling
staffs etc on soft ground. I couldn't tell you where to get them but
I hope this is of some help.

Hi Bill,

On my GM-8 I use celestron anti-vibration pads. But the G-11 has much
larger legs, so you'd probably have to make something. It wouldn't be
difficult, to cut some plywood into 4-5" diameter circles, and put a
layer of "Sorbathane" (sp?) between them to reduce vibrations. A
doorstop, or similar knob, could act as a centering plug for the G-11
legs.

This could be quite elegant :-)

I use the G-11 with the Celestron anti-vibration pads. All you
have to do is turn the legs 180 degrees and the curved outer
end of the legs fits nicely in the cup of the pads. This combination
works very well.

Hey Bill,
An easy fis would be to put a small square of plywood under the legs, when
on soft ground, it should do the trick.
