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. Bill |
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.

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 :-) Robert. -----Original Message----- |

Hi Bill,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. Rockett Crawford ---------------------------------------------------------------------------- Capella's Observatory (CCD Imaging) |
