Explore Scientific's 8x50 Erect-Image Illuminated Finder Scope (part # VFEI0850-01) is a fine optical instrument in its own right. It features a fully multi-coated achromatic objective and eyepiece for maximum contrast, and produces a wide 6° field of view. A precision polished roof prism produces images that are right-side-up, left-to-right correct. In other words, things are not upside-down and backwards like most viewfinders.
The Explore Scienitific straight-through finder has a precision glass-etched illuminated reticle with cross-hair to mark the field boundaries and an open circle in the middle so that stars can be perfectly centered without being covered. It has scale markings for 1.5°, 3°, and 4.5° (the edge of the field of view is the 6° boundary). The 55° apparent field, long eye-relief eyepiece produces a bright 15.5mm exit pupil and will allow you to find faint galaxies, comets, and nebulae. The deep red illumination is continuously variable to provide the desired brightness.
Focus for the objective and the long eye relief eyepiece have threaded locks, allowing precision focus of both the main objective and eyepiece illuminated reticle. Finder also includes two end caps. The tube sports a handsome silver finish.
The finder comes with a 50mm finder bracket. Please note that no finder base is included as all Explore Scientific telescopes already include this base as standard equipment. However, you can also buy this base separately if required for other telescopes (Explore Scientific part # FNDRBASEBLK). Please also note that the included finder bracket will mate with this optional Explore Scienitifc finder base only. It will not work with Tele Vue, Antares, or other brackets that have a similar design but different dimensions.

I usually use right angle finders with a correct view, so I wasn't sure if I'd enjoy it. I have it mounted on a refractor that is tall enough not to have to bend over. Easy to bring my eye to and has a nice field of view. Very sturdy. Great finder!

A great ViewfinderPros:

No Right AngleComments:
This is a nice viewfinder which is constructed out of good materials. It's also attractive and looks great on the main scope. The cross hairs are top notch and the illumination is great. I use a couple of different finder scopes. My other has right angle and that's handy while searching for objects that are straight up or near. I plan on getting a Refracting Telescope soon and this will then be used on that one...leaving the other for my C8.
