- 8x50 finder scope; 50mm large objective lens enables more light to enter; providing a bright image; making it easy to aim anywhere in the sky; a large field of view of 7.3 degrees;
- Erect image and humanized design; built-in BK7 correct-image roof prism ensures right-side-up; left-to-right correct views; which is in line with the basic observation habits of people;
- Dark field illumination function; under extremely dark observation conditions; the red LED illuminator can illuminate the reticle; assist observation and facilitate finding the target;
- Glass reticle; the glass reticle has higher seismic stability; high precision and long service life; at the same time effectively avoids the problem of the cross line blocking the target;
- Objective lens thread focus and reticle parallax compensation adjustment; ensure the target and the reticle are in the same focal plane; angle adjustment control knob can adjust the reticle and observation angle.

Very Good Finder!
A finder is a tool to find objects, and to find them you should look through it in a correct way the way you see things, not upside down etc. With this finder except you see and find correct the objects with the red illuminated lines, you can detect easily the objects in a very dark skies. With my sort experience, turn on the Illumination in dark skies when you find first the object in the finder and then to bring it in the red cycle. I recommend it, because it has high quality of materials and very good functionality!
Got a nice view of Jupiter on the first day!
I was able to line up on Jupiter and 4 of its moons on the first evening out using this diagonal. I am using on a classy old Orion/Vixen VX80. Having the 90 degree diagonal in place instead of the 45 degree unit it came with makes it a lot easier on the back! And the view was just as spectacular as you can hope for. No distortions or difficulty at all from this part. Be sure that you are aware of the physics of a mirror diagonal, the image you see is upside down. That does not matter quite as much with stellar objects, but it does mean your motions of the scope feel weird as it moves in apparently the opposite direction.
It was my solution to get ISS
Needed a correct image guide scope to manually track orbiting objects with a telescope that didn't have a 90 degree eyepiece. This is exactly what I was looking for, and the parallax adjustment feature that I hadn't noticed when I ordered it, makes it 10 times better for my needs. I wouldn't use it to auto guide, but it's perfect for chasing down the Space Station by hand if that's what you into.
