I have for sale a Ken Dauzat 3-in-1 bracket for the various Synta 150mm F8 refractor telescope tubes. This bracket does three things:
1.) Provides a movable counterweight at the rear of the telescope to balance out the front-heavy tendency. This allow a more comfortable observing height.
2.) Has a mounting ring for an 80mm F5 short tube refractor to use as a really, really big finderscope. The weight of this smaller telescope also helps in the balance.
3.) Has two handles which make the "beast" easier to manhandle, er, personhandle onto the mount.
This one is in excellent condition. It uses non-marring nylon screws to fasten it to the CR-150 and hold the 80mm short tube. There are a few minor scratches in the paint but everything works as it should.
A new one from Mr. Dauzat is $225 plus shipping. You can have this one for $150 shipped by Priority Mail in the USA.
