Will your imaging train vignette?
Check which filter and adapter sizes clear the sensor with the Tele Vue Starbeam Flip-Mirror (upgrade for older Starbeam models), and how much light the corners lose.
The Tele Vue Flip-Mirror (SFM-1005) is the flip mirror for the Starbeam reflex finder, sold on its own to upgrade older Starbeam models. It is not a standalone accessory: it attaches to the Starbeam's illuminator housing. Tilt it back and you can see the reflection of the Starbeam's beamsplitter mirror/lens in the flip mirror.
How the Flip Mirror Works
To use the flip mirror, simply tilt it back until you can see the reflection of the Starbeam's beamsplitter mirror/lens in it. It sits on the Starbeam finder, not in the telescope's light path.
An Important Compatibility Note
This is a specialized component, not a universal accessory. The Tele Vue Flip-Mirror (SFM-1005) is for upgrading older Starbeam finders; it attaches to the Starbeam's illuminator housing and does not fit a telescope focuser or diagonal.
What specific Tele Vue products does the SFM-1005 upgrade?
This unit adds the flip mirror to older Starbeam reflex finders, so the red star can be viewed from above as well as straight through. It is not a standalone product: it attaches to the Starbeam's illuminator housing.
Can I use this to build my own custom flip-mirror system?
No. The SFM-1005 is the flip mirror for the Starbeam finder and fits the Starbeam's illuminator housing; it is not a telescope flip-mirror diagonal.
