Straight Correct Image Finder

Does anyone make a 9x50 straight thru finder? I can find 9x50 in a 45 degree or straight 9x50 inverted, but can't seem to find both straight and correct image in 9x50.

Anybody seen one? Thanks.

Yes, but they're more commonly known as a rifle scopes.

I don't know of any 9x50 straight correct image finders, but I made a similar one out of an old pair of 7x35 binoculars. In my opinion, it far out-performs any finder on the market (though a larger aperture would be helpful). It took a fair amount of tinkering, and since the binoculars have no cross-hairs I drilled a hole at the focal plane and inserted a small screw to mark the center of the field. The screw is easily visible in dark skies without illumination. If you're interested, I could write more details.

I've used conventional (inverted image) finders and a Telrad; it seems to me that the correct-image straight-through finder combines the best features of both. You can see much fainter stars than with a Telrad, yet can easily relate the finder view to the naked-eye view or the star atlas (held right-side-up).

You would have to fabricate a finderscope mount for it, but I always thought the EagleEye 8x32 monocular sold by Orion would make a good finderscope:
