Ground vibration!

Hi All,

I have one little question, may have been answered in this forum.
How to stabilize Pier when the ground brings vibration?

I live in an area, close to railway tracks, about 1/4 mile and also 200 ft from somewhat busy road.

As, the soil is sandy, upon using tripod, I hardly get the vibration up to the scope. But if I am on the driveway (concrete), it’s gets nasty.

I was planning to make a permanent pier, but after all the recent results, doubt the heavy Concrete base of the pier will be stable if vibrations are from the ground itself.

Any suggestions please!

Thank you all,
Ansuman.

I don't know about the pier, but for a tripod, you should try Vibration Suppression Pads (VSP's). They are hockey puck size disks with foam insulating that dampens vibrations between the tripod and the ground. You still see a second or two of shaking, but it stops faster with the pads under the tripod legs. Meade, Celestron, and Orion sell them for about $50 a set.
