Zhumell 1.25" to 0.965" hybrid 45º erecting prism od45ab - Zhumell 1.25" to 0.965" Hybrid 45° Erecting Prism OD45AB

Breathes new life into my old Celestron C90 spotting scope. Works well with the 1.25 eyepieces from my other telescopes too. Makes the scope a nice terrestrial spotter, everything right side up.
Pros: Can use larger eyepieces now & better field of view
Cons: There is none
