The Altair Astro Wave series 80mm ED Triplet APO refractor uses a 480mm focal length air spaced apochromat lens with Japanese FPL53 ED glass from Ohara. A rigid aluminium tube with two tube rings allows stable mounting for astro photography, and the rotating 2.5" Rack and Pinion dual speed focuser can handle heavy loads whilst keeping the telescope light.
For visual observation, this telescope offers razor sharp, high contrast images, without any colour aberrations whatsoever in a very portable package.
For astro-photography, the Altair Planostar 1.0x Field Flattener (PLANOS-2-1.0-80-F6-M48) converts your Wave Series telescope into a flat-field astrograph at it's very fast F6 native focal length. DSLR and CCD adapters are available for attachment of various cameras (see associated products for more info).
Altair 80mm Super ED Triplet telescope optical tube with serial number engraved on the lens
Optical test report corresponding to the serial number
Telescope tube rings
Vixen-format 1.75" dovetail bar
New CNC machined dual speed "Rack 'n Pinion" focuser with self-centering 2" pushfit adapter and Teflon tipped rotator
2" to 1.25" Self centering adapter
Front metal objective cap
1.25" plastic rear insert cap
a "free" foam filled transport case
This latest version includes a lighter weight OTA and a light weight dual-speed "Rack 'n Pinion" focuser, Teflon-tipped adjustable rotator, CNC machined internal knife edge baffles, and a self centering 2" rear adapter, and even a 2" to 1.25" self centering adapter with brass compression ring (sold by some companies for £50 on it's own!). Optional Field flatteners can be attached directly by unscrewing the self centering rear assembly and removing it from the focuser.
Tube rings are provided with standard M6 hole patterns to fit most hardware mounting systems on the market, and are fully compatible with the Altair TMS Telescope Mounting System TM.
We recommend the Altair Astro 60mm Deluxe Finder Scope (see related products) which is a perfect fit and can double as an autoguider for imaging.
As a portable wide field refractor for astro imaging or visual use, this is an extremely capable telescope in all areas. Colour correction is excellent, and contrast is very high, enabling faint and subtle details to be observed visually or in images. The optical tube assembly is perfect for even modest sized mounts such as the EQ3 upwards.

Altair Wave Series optics: Your 80-480 Super ED Triplet APO optics are repeatedly tested and re-figured at the final stages of production, until signed off by the optician in charge of the production batch. The best quality Ohara SFPL-53 glass is used in the ED element, which is fully annealed and cooled over several days to relieve internal stresses, having an Abbe number of 94.94, plus or minus .01 per batch. SFPL-53 is referred to as Synthetic Fluorite or Super ED. (Fluorite crystal by comparison is 94.99 but with slightly more variation from batch-to-batch, and has less stable chemical, thermal and physical properties). Each lens cell has a serial number engraved on the front ring. Working closely with our optical technicians, we have introduced a second and unique quality assurance process for all Wave Series lenses, to ensure the highest quality and lowest chromatic aberration. These lenses are modified, and are far superior to the "normal" production quality lenses offered by most manufacturers. Star tests speak for themselves, and colour correction is superb, as can be seen from the various observing reports and images taken with Wave Series refractors. Blue stars show negligible bloat in long exposure images. During the production process, a laser interferometer image is acquired in 532nm green light, and imported into fringe analysis software to create an optical test report. Each image is a "snapshot in time" of the lens on the test bench. Vibration, air currents and other environmental factors can influence the image and the outcome of the report slightly, though are minimised during testing. Providing a test report is a useful way for us to assure that our our internal production quality is consistent from batch-to-batch. A paper report printout is included with your telescope, which corresponds to the serial number visible on the lens (an example report is shown in the thumbnail images below the main product image, with serial number deleted).
