REDUCED 45 deg Binocular Mirror Table $125 + shipping OR $110 pickup in San Francisco N or E Bay area

A wonderful mirror table made for binoculars up to and including "giant" binoculars, 50mm through 80mm straight through binoculars with a 1/4-20 tripod thread in the front center of the binocular hinge.

The front surface mirrors are thick (7mm?) and flat and give excellent images on the few times I've used it- I switched over to 45° 100s a year. These make use of straight through astro binoculars far more pleasurable, without the extreme cost of 45° or 90° prism binotelescopes.

One mirror has 3 point collimation screw adjusters- Care must be taken not to over tighten them since I believe the flats to be RTV mounted.

I believe they were powder coated, with the attractive speckle paint.

The 112mm diameter (approximate) front surface mirrors are in excellent condition (with a few tiny specks of dust, etc. that don't blow off).

This will easily accommodate 80 mm giants 1/4-20 mount threads in the front of the hinge, and worked well with my 20x80s.

Whether they will accommodate 100 mm binoculars will depend on the barrel lengths. The distance from the hinge thread mount to the nearest part of the mirrors is approximately 7" / 175mm, adjustable up to 8" / 200mm so it will depend on the binocular design (there are three clamping mount distances)  if your barrels are less than 8 1/2" from the hinge mount they should fit, and the mirrors are generously sized.

If you have 80 mm binoculars, you should also check that clearance from the hinge threads to the bottom of the barrels, most should easily fit.

I don't recall seeing these recently except for the ones by oberwerk which only accommodate 70 mm binoculars, and these are much larger.

An absolute "must-have" for anyone using straight through binoculars for astronomy!!
