The unique design of the Tele Vue Starbeam 1x39 Finderscope Quick Release Baseoffers two modes of use: straight-through line-of-sight, or 90° angled viewing when the optical tube assembly (OTA) is pointed high overhead at or near the zenith. A mirror flips up for a more comfortable viewing angle when the tube is pointed up, and simply folds down when the OTA is pointed more parallel to the ground.

This scope is configured as an unmagnified finder with a larger 39mm aperture for a wide field of view and a 6 arc-min accuracy. In its straight-through setting, you see the natural sky with a 10 arc-minute field of view, and when using the mirror flipped up, the sky orientation is the same as when viewing through the scope's eyepiece. A center red-dot reticle helps with precise positioning and controls allow the brightness and blink rate to be adjusted.

This version of Starbeam comes with a Tele Vue Quick Release (QR) bracket and a dovetail. The QR bracket easily mounts to channels in the Tele Vue ring mounts and mounting rings—this makes installation and removal quick and easy for transport and storage, or for installation on other OTAs. The QR base will also fit on Orion and Sky-Watcher finder shoes as well as on some Vixen models not made in Japan

Q: 6. How does this work with the Meade LX 600 12”? Would it be too much? I would like to do planetary photography with either a Nikon D750 or a Nikon Z6. Thanks

A: This would work with the LX600,but might be very dark/distorted. You can definitely try it with the Scope. The View just might be a little grainy due to the high magnification.

Q: 7. What I feel that needs to be better explained about eyepieces and focal lengths as in 6mm or 25mm is that the opening is tiny for 6 mm as compared with 25mm that is wider . The lower the focal length the difficult it gets to train your eye throughthe opening due to its tiny opening. My child experience with my first kid telescope that came with 6mm and 25mm eyepieces told me that 25mm is more enjoyable to use despite lower magnification than the higher magnifying 6mm which is so restrictive in the opening for my eye to keep peeking through as steadiily as I can. I think that a minimum of 10mm is acceptable to me or maybe 12mm. . Am I correct?

A: Yes that is correct. 10 or 12mm will be okay. It also depends on how large of an aperture your scope has. The bigger front opening of the scope the brighter the image.

Q: 8. I'm considering purchasing a TeleVue 90-Degree Everbrite 2 Mirror Diagonal for my Celestron 8 HD OTA. Do I need the TeleVue Schmidt Cassegrain Adapter functionality to connect the two?

A: Yes, you will need the adapter. You can go with the long or short SCT adapter. I use the short adapter with my 8 and the long with my 12 SCT.

Q: 9. Could I use this with my Meade 125 etc?

A: If your telescope has a 1.25 eyepiece opening then this eyepiece will work. To determine if your scope does I will need to know the exact Meade Model that you have.
