Alternative to Vibration Suppression pads?
I made a set like that once, used red silicon caulk.. waste of time and
money since it was nowhere as effective as a set of celestron pads. On 14 Jul 2003 10:21:23 -0700, (Chris Nicholl) wrote: I made some myself, using a method I saw posted on Astromart. If you get some of the large furniture-leg pads, then fill them with caulk and let it cure, you'll get a set that works very well. I haven't compared them to the commercial sets, but my pads dampen the vibration on my AT1010 by about 50%. Chris Nicholl Herm Astropics http://home.att.net/~hermperez |

Alternative to Vibration Suppression pads?
Starpads work good for the money.

They consist of an inner and outer layer of hard plastic and that sandwhiches an inner layer of sorbothan. The Meade, Celestron and Orion versions are all the same principle. Adorama in NY usually has very good prices on them. The problem with just buying a piece of sorbothane is that it "spreads" out and if you simply put it under the legs it would squish and probably tear quickly. Frankly...they are cheap and probably one of the biggest improvements you can make for your telescope to reduce vibration. I use them on all my telescopes and mounts..from my camera tripod mounted binocs...to my 11"Nexstar GPS on a Meade GFT and 6" APO on a custom tripod with German mount. I usually see at least a 50% reduction in vibration. It is also extremely effective at minimizing wind harmonics. To be most effective you should remove any existing rubber crutch tips so the metal legs rest directly on the pads. I have also tried using a 1/4" sheet of rubber...that worked somewhat...about 20% reduction...but not much more than rubber crutch tips. Bob Berta (Otto Parets) wrote in message . com... Does anyone have an idea for an alternative to those expensive vibration suppression pads? I thought of some dense rubber, but I looked for a thick sheet of rubber at the hardware store and came up empty handed. Thanks to all who can help. Clear skies, Otto Parets |

Go to http://www.mcmaster.com/ and search for Sorbothane. You can get a 4"x4"x.5" sheet of it for around $8. I'm not sure what hardness Celestron and the like use in their pads, but McMaster offers 40, 50, and 70 OO. If anybody tries this route, I'd like to hear their report ... |

Alternative to Vibration Suppression pads?
The other thing that I found works for me is to connect the legs of the
tripod about halfway down the legs tightly, so that they can't really move or jiggle independently. This helps with vibrations even with a lot of people walking or running around your scope, such as at a public star party. --- Dave -- ---------------------------------------------------------------------- Never be afraid of trying something new for the love of it.
