Altair Lightwave 66mm F6 ED-R Refractor with Dual Speed R&P Focuser with Case

The Lightwave 66/400 ED refractor delivers high quality colour correction. The ED doublet lens system features an ED element made from premium Japanese Ohara glass. The elements have been figured with excellent smoothness and very effective super-high transmission coating on all air-to-glass surfaces for exceptional contrast.

The Lightwave 66 ED-R is a very versatile telescope, performing very well at both visual observing and astro-photography. Detail is visible on the larger planets such as Jupiter, with both the four principle moons and main cloud belts easily visible at high power.

With the right eyepiece the Lightwave 66 ED-R with it’s F6 focal ratio and 400mm focal length is within the ideal performance range to capture the entire disc of the sun at low power, enabling viewing of solar prominences and their development over a few hours.

The dual speed “Linear Power” Rack and Pinion Geared focuser has eight adjustable internal roller bearings, so you get more “lifting power” and stability for large eyepieces or cameras.

The focuser has a 2″ rear accessory port with brass compression ring and a 2″-1.25″ adapter with brass compression ring and dust plug.

The Lightwave 66 ED-R comes in a tough hard skinned aluminium flight-case with a foam insert, and pre-cut removable inserts for an eyepiece, a diagonal and Red Dot Finder, making it the ideal “grab ‘n go” portable telescope-kit for visual observing or astro-photography. The case measures 39x25x19cm and is lockable with 2x keys included.

Attaching the telescope to a photo or video tripod mount takes mere seconds by means of the 1/4″ photo thread on the dovetail-base.

Most GOTO mounts which support “Vixen/Synta-format ” dovetails will fit directly. The mounting base can be detached and re-mounted facing backwards to change the balance point for smaller loads.
