Megrez 72 FD Doublet APO

The Megrez 72 FD Doublet APO operates at F6 and is a true multi-purpose tube assembly.

It incorporates excellent mechanics, fit and finish and with it's Crayford 2-speed fine focuser, super-high transmission multi-coating, optional white ABS backpacker type carry case that will fit all of your requirements.

The Megrez 72 FD Doublet APO operates at a fast focal ratio which makes it the perfect travelling companion for travel astrophotography, piggybacking or simply as a spotting scope.

The lens design is ED glass doublet air-spaced, in CNC machined ultra-high precision lens cell, and each lens is fully multi-coated with a special super-high transmission coating (STM Coating) on all surfaces.

Additionally it is fully baffled to block all extraneous off-axis light rays and prevent glancing reflections, increasing overall contrast

There is nothing that has been left to chance with this scope. It is excellent for EAZY-T Alt-Az Mounts. It is also possible to slide it directly into the mount without a dovetail plate if you prefer.

And as you would expect from William Optics, this scope has quality fit and finish: powder-painted white CNC-machined aluminum tube drawtube, travel length 81 mm with graduated scale. Retractable dewshield, smallest size ever and improved portability.

It is an astrophotography delight, offering a fast focal ratio for bright, high-quality astro-imaging. A dedicated field reducer/flattener is also available.

The William Optics rotatable Crayford focuser is both smooth and precise, making it ideal during astrophotography. Adjustable focuser tension. Super-smooth and reliable 1:10 micro focuser for fine focusing during imaging and visual observations alike.
