Observatory - Tripod on floor, no pier
Posted 31 January 2013 - 07:03 PM
My initial thought was to biuld a pier for the G11 and a ground mounted pier for the Dob. In both cases this would isolate the scopes from the floor of the observatory.
The observatory will be wood framed with an elevated (corner supported) wood frame floor covered in plywood. Both scopes are just for viual and 98% of the time I will be alone.
My question is - has anyone just put their tripods (G11) or Dobs directly on the floor? I could use vibration pads on the G11, or build plywood/foam sandwich platforms to help isolate the scopes for the floor.
I do not want to go to the expense and time to build piers if just putting the scopes on the floor will work reasonably well.
Any thoughts or first hand experience will be greatly appreciated.

For astrophotography you have a whole different situation assuming you would like to take longer exposures (i.e deep sky images rather than planets). Then you need a concrete floor or a pier because every time you twitch a body part, the exposure is likely to be ruined.

I contemplated putting two permanent piers in my tiny roll-off and decided instead to put in one large permanent pier and then build the floor strong enough to hold a tripod setup sturdy enough for most AP work if folks aren't practicing for Riverdance. So, I have 2x10's with 8' spans placed on 12" centers and then covered with 1 1/8" plywood.

I think I will try without piers.
