Denkmeier Binotron-27 Super System - power switch, OCS-A37, matched eyepieces, case

Denkmeier Binotron-27 binoviewer, Super System configuration. This is the full setup with the dual-arm power switch, not the base unit — three magnifications from a single pair of eyepieces.

Included:

• Binotron-27 binoviewer body with Collitron eyepiece holders
• Dual-arm power switch (this is what makes it the Super System)
• OCS-A37 optical corrector cell (required for refractors and Newtonians, not needed for SCTs)
• 2x Denkmeier DK32 32mm Plossl eyepieces (optically matched pair)
• 2x Orion Expanse 20mm 66° eyepieces (matched pair)
• 2x Orion Expanse 15mm 66° eyepieces (matched pair)
• Denkmeier aluminum hard case with laser-cut foam

That's a complete binoviewing system ready to use — binoviewer, corrector, power switch, and three pairs of eyepieces covering three focal lengths. A buyer does not need to source anything else to start observing.

Condition: very good. Everything functions and moves smoothly. No visible damage to the body, prisms, or optics. The case foam is intact.

This comes from a collection I inherited. I'm not an astronomer and have never used a binoviewer. Everything I've described is based on careful inspection and identification rather than observing experience. If you want a specific photo or measurement, ask and I'll get it.
