Product Description

Product Description
Sometimes looking through a straight finder scope can be a strain, making you crouch down and crane your neck. Well, you can call off the chiropractors because our right-angle finder scopes let you view in contortion-free comfort! What's more, they have a built-in Amici prism to provide a correctly oriented view - not upside-down as with standard finders. These achromatic, crosshair finders feature fully coated glass lenses, internal baffling, and focus adjustment. Each includes an aluminum bracket with two perpendicular thumbscrews for easy alignment. Dovetail foot fits many Orion telescopes (see list). Dovetail base (#7214) can be purchased for custom installations. Prism and eyepiece are not removable.

2.0 out of 5 stars OK for Alt-Az, useless for Equatorial mount, March 4, 2005

By	Michael Dubson (Boulder, CO) - See all my reviews (REAL NAME)

Good optics, good construction, but one major design flaw which makes this finder scope useless if you have an equatorial mount: It is impossible to rotate the right-angle eyepiece assembly about the axis of the finder scope. This is not a problem if your telescope has an alt-az mount, but if you have an equatorial mount, then, regardless of the initial orientation, the finder eyepiece will be pointing toward the ground for about 1/2 the sky. I complained about this to Orion tech support and they promptly and politely replied that this is indeed a problem. My rating of 2 stars is an average of 4 stars (for the alt-az owners) and zero stars (for the equatorial owners).

4.0 out of 5 stars Nice, inexpensive upgrade, June 18, 2004

By	Zhimbo "zhimbo" (New Hampshire USA) - See all my reviews

This is a reasonably priced upgrade for the 6x30mm finder that came standard with my scope. The extra aperture provides much brighter views, the right-side up image simplifies matching the view to my star charts, and the right angle is a real neck-saver on long observing sessions.

Optically fine though there is some edge distortion. No problem for use as a finder, though. If you've never used a right angle finder before, be warned that initial orientation is little harder than with straight-through finders. I added a zero-power "bulls eye" finder to help with this. This combination makes finding things very easy.

5.0 out of 5 stars Very worthwhile, March 31, 2009

By	black thumb (Berkeley, CA USA) - See all my reviews

First off, ignore the reviewer who said you can't rotate the tube in its holder. If that was ever true, which I strongly doubt, it's certainly not the case in the versions that have been shipping in recent years. The scope is secured by three bolts, one of which is spring-loaded. Just pull out the spring-loaded bolt and turn the scope however you like.

I got one of these to replace the 6x30 finder on my XT6 dob. I have never regretted it for a second; on the contrary, even a year after the switch it is nice to grab such a big chunk of sky at such a useful magnification. You will see more stars with this thing and it will make your star-hops easier. What more is there to say?
