Description
This 1.25" Variable barlow will allow you to change the magnification of any 1.25" eyepiece by 1.5X to 2.5X. This can be done while observing, although re-focusing is required after any change. There is no vignetting, even with low power eyepieces.
For refractors that came standard with an extended 2"-1.25" adapter, (Celestron, Sky Watcher, Orion etc) either of our parts MDA (low) or LPRA (ultra-low) will be required for the necessary in-focus.
Barrel Diameter - 1.25"
Focal Length - 60mm
