Altair Lightwave 72mm F6 ED Refractor with Dual Speed R&P Focuser with Case

The Lightwave 72/432 ED-R refractor delivers high quality colour correction, delivering the high contrast images refractor owners appreciate. The ED doublet lens system features an ED element made from premium Japanese Ohara glass.

The Lightwave 72 ED-R is a highly 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 70 ED-R, with it’s F6 focal ratio and 432mm focal length, is ideal for capturing 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. Fine tilt-adusments can be made using the focuser, allowing astro-photographers the ability to fine-adjust the optical tube to produce very round stars at this fast F6 focal ratio.

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 72 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.
