[OM] Mounting a small Takahashi, was: Valentines Day

[Chuck Norcutt]

If I had a scope as expensive as a Takahashi I think I'd spring for the 
factory specified mounting.  But, if you'd like to save some money, here 
is the URL for a pair of 76mm ID tube rings for $15 from Orion.  You 
would have to shim these down to 68mm using felt or cork, etc.  Then 
mount to a metal or wooden plate tapped for the tripod screw.  If you 
use a wooden plate you can fit it with a "T-nut" so there are metal 
threads in the plate.

You could also make a substitute for the mounting rings.  Simplest might 
be a pair of wooden V-blocks with felt or cork facings and some sort of 
adjustable strap to hold the tube tight.

Whatever you use should be readily loosened so you can slide the tube 
back and forth for balance.

Good luck,
