having recently finished the construction of a 4.2m x 3.6 m roll off roof observatory I am testing out a 16" Newtonian mounted on an SB Paramount ME gem. I have a 1m deep, 1.5 tonne concrete base upon which is mounted a 1m tall steel, vibration finned pier. However, I get traffic vibration from a nearby road which ruins my images.
Usually I separate the concrete from the ground with 50 - 70mm of polystyrene sheets which on my other telescopes in the vicinity appears to have worked as I have no problem. I think I forgot to include this precaution this time. I am thinking of using Sorbothane as a vibration dampening material placed between the concrete and the base of the pier and/or between the top of the pier and the base oft he mount.
Has any body tried this solution and how have they got on? -ve replies accepted, but not enjoyed.
