The AR127 (five-inch) model, is a classic air-spaced, crown-and-flint doublet achromatic refractor. Our goal was to provide an extreme value by providing true diffraction-limited optics at a price that will allow more people to explore the sky with a wide-field (f/6.5) large aperture refractor. Images of deep sky objects are stunning at low to moderate magnification, and all at a small fraction of the price you would pay for a similar aperture apochromat refractor.

The dual speed 2" focuser featuring compression rings make focusing easy without blemishing the eyepiece tubes. The 2" 99% dielectric diagonal also ensures minimal contrast lost, maintaining the telescope's bright and crisp images.

Constructed using heavy-duty, high-quality parts, this telescope is well suited for the demands of public outreach. The cradle ring assembly with a built-on Vixen style dovetail and carry handle simplify transportation and ensure the telescope will be solidly mounted.
