Long Perng ED f/6 66mm Doublet Refractor is a perfect first-time imaging scope capable of capture any celestial target.

The Long Perng 66mm ED APO Apochromatic Refractor Telescope has a beautifully machined Crayford-type which accepts all 2"/1.25" universal telescope eyepieces accessories. The gearless Crayford design provides smooth, zero image-shift focusing.

The focuser is rotatable 360 degrees, allowing comfortable eyepiece positioning or easy image framing when you’re taking pictures.
