Have you ever wished you could simply point and shoot your telescope? Well, now you can. With the OPT Red Dot Finderscope, aiming is as easy as aligning the red dot on the target area. (Note: Red dot appears on the screen and not in the sky.)
OPT Red Dot Finder
The non-magnified LED screen provides a clear window to the stars and the adjustable brightness red dot provides a visual reference to where the telescope is pointed - day or night. The OPT red dot reflex site makes a great accessory to all telescopes, including birdwatching and binoculars.

Product QuestionsAloha OPT, Will the female shoe/base fit on an Astro Tech 72mm ED refractor? According to Astro Tech's documentation, the scope comes with small 5mm screws already installed on the OTA (which I have verified). But the length of those little 5mm screws seems to be only about 1/4" (at the most)... ie, they don't look long enough (to me) to mount any kind of base/foot. thanks!Question by: John on May 8, 2016 1:59:00 PMHello
OPT red dot finder has adjustable brightness controls ?
Actually back order how many time to have it ?
thank you for your answerQuestion by: Gourmet Gerard on Nov 21, 2015 5:45:00 PMQuestion by: James on Apr 3, 2016 3:24:00 PMQuestion by: Obert Tufte on Dec 4, 2015 10:27:00 AMUnfortunately, not without modification. There is no mounting surface on the ETX 90 for a conventional finder, so you would need to add a strip or two of double stick tape under the quick release base to attach to the tube and then you can swap the finder on and off easily.Answer by: Chris Hendren on Dec 4, 2015 12:35:00 PMWhat is the overall height, from base of the dovetail (part attached to telescope) to the top of the flat area of red dot finder?
