Altair Astro Wave 130 F7 ED Triplet APO

The Altair Astro 130mm F7 ED Triplet APO refractor uses a 915mm focal length lens cell with Japanese FPL51 ED glass from Ohara which is cpecifically chosen to be free of internal stresses and striae which affect optical quality in large size refractors.

This telescope is not like other telescopes using the similar or the same mechanics and has rapidily gained a reputation for performance above the norm especially with visual observers. This is due to a special modification process at the final stages of production, cluminating in the production of a laser interferogram image which is delivered with every telescope.

NEW 2014 Version with a light weight dual speed "Rack 'n Pinion" focuser, Teflon-tipped adjustable rotator, CNC machined internal knife edge baffles, and a self centering 2" adapter. Field flatteners can be attached directly as usual by unscrewing the self centering rear assembly.

What makes the Wave Series different from other refractors of similar specification? Every single Wave Series scope has been tested individually and signed off on it's optical quality before shipping. A test report is provided with each scope and each scope as a serial number engraved on the lens cell corresponding to that test report. This teting is done by an optical lab employed by Altair, and the results are nothing short of spectacular, as witnessed by customers. Altair usually takes the top 10% of any glass production run from their suppliers, then tests each scope a second time before the lens cell is assembled and collimated with serial number engraved on the lens cell, and we pay extra for this service. That is why we are confident enough to provide an optical test report with each Wave Series telescope. Altair call this "grade 4 optics". Altair never source sub-standard or rejected optics, and any optics which do not meet criteria are sent back to the supplier without a serial number. Altair always purchase the highest grade of glass available for each production run, to differentiate their product in the market. What's more, Altair guarantees your Wave Series telescope will arrive in perfect collimation, and will always ship them using a fully insured professional courier service, so your telescope is guaranteed to arrive ready for you to enjoy.

A rigid aluminium tube gives the correct thermal properties for any large airspaced triplet refractor, allowing the use of Kendrick dew control heaters to conduct heat to the optics, and quick thermal equalisation and relative freedom from tube currents, unlike carbon fibre or non-metal composite materials which are not only brittle but often hinder thermal equalization because they do not conduct heat. Two two heavy duty tube rings gives a stable mounting platform for astro photography, and a large dewshield delays the onset of dew and keeps dust and pollen away from the objective.

The objective cell can easily be adjusted in tilt by the customer, by accessing the front push-pull tilt adjustment screws when the dewshield is unscrewed (see thumbnail pictures).

This new production run includes our new Rack and Pinion geared dual speed focuser with self centering 2" collet adapter and machined internal baffling system. This, and an inevitable increase in the price of the 3rd tier optical modification and QC service we employ for all Wave Series telescopes, has increased the product price over the previous production run. The price and specification of this product is subject to change without notice.

The new Rack and Pinion dual speed focuser has a smooth teflon loned rotation system and a self-centering 2" pushfit end-cap. The end cap can be removed to attach the PlanoStar TM 3" 1.0x Flattener and the Planostar TM 3" 0.79x reducer by means of a threaded adapter. (Options available in the dropdown menu when ordering).

Two heavy duty tube rings are provided with standard hole patterns to fit most hardware mounting systems on the market.

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).

The Altair 102-715 EDT is the ideal multi-purpose telescope platform, suited for the amateur astronomer interested in both visual and imaging use, and offering excellent performance in both areas. It offers a wide-field or a high power view, and is therefore more than a reflector, enabling high contrast views of both planets and wide field deep sky objects.

and crafted optics: Your 102-715 Super ED Triplet APO optics are hand figured at the final stages of production and repeatedly tested until signed off by the optician in charge. The best quality Ohara SFPL-53 glass is used in the ED element, which has an Abbe number of 94.94 plus or minus .01 per batch. SFPL-53 is referred to as Synthetic Fluorite or Super ED.

These lenses are extensively modified, and perform far in excess of normal production quality lenses. Star tests speak for themselves, and colour correction on images is the best in it's class, as can be seen from the various images taken with the Wave Series refractors - with blue stars in particular. A laser interferometer image in 532nm green light is included with your telescope. This is the final test image created once the optician has completed your unique objective, and stands as a certificate of quality attained by Altair Astro's unique second-tier production process.

Optional Altair PLANOSTAR 3" Field flattener for astro-imaging: A optional, dedicated large format field flattener is available separately with this telescope package for use with CCD imaging chips. The large format 3" field flattener screws directly to the rear of the focuser (the 2" push-fit adapter can be removed) to reduce flex in the imaging train with threaded-only connections, resulting in tighter star images, and sharper images. A conical rear adapter with an M48 rear thread is included, and the correct spacing for Nikon or Canon EOS DSLR cameras can be obtained with the special Altair Astro low profile Canon DLSR adapter, or the standard Skywatcher Nikon M48 DSLR adapter. If you have a CCD camera, our variable M48 spacers can be used to get the right distance to the CDD chip. (See associated products below for the Altair Planostar 3" field flattener).

3" Focuser for astro-imaging: The large format rotating 3" CNC machined focuser offers a rigid and stable platform for imaging use. The pushfit adapter accepts all 2" accessories for visual use, such as star diagonals. It features 3x clamps, and a brass compression ring, offering increased rigidity compared to single screw designs. The focuser can be fully automated and motorised within minutes with the optional USBnStep motor focusing systems we offer separately. We are currently testing an optional Starlight Feathertouch focuser is also now available to fit the Altair 102-715 and Altair 130-905 EDT APOs which all use the same focuser. Our USB nStep motor focuser unit is also offered with adapter set to fit the Starlight Feathertouch 3" focuser available separately. Please enquire as to pricing and availability for these options.

Altair Wave Series 115 F7 ED Triplet APO

The Altair Astro 115mm F7 EDT APO is a highly specified triplet APO refractor which significantly outperforms 4" refractors both in resolution and light grasp, whilst still remaining quite portable.

The Altair 115mm F7 EDT is the ideal multi-purpose telescope platform, suited for the amateur astronomer interested in both visual and imaging use, and offering excellent performance in both areas. It offers a wide-field or a high power view and is therefore more versatile than a Cassegrain type reflector, enabling high contrast views of planets and wide field deep sky objects.

The Altair 115mm APO sports a triplet air-spaced lens cell for better colour correction than normal doublet or dual lens telescopes. This results in higher contrast, and a cleaner sharper image with less spurious colour. The combination of a triplet ED lens system with high surface accuracy and the fact that this telescope does not have a central obstruction like a reflector telescope, means that it will deliver increased contrast compared to a reflector telescope such as a Schmidt Cassegrain or Newtonian of slightly more aperture, revealing more detail.

Skywatcher Startravel 80 Optical Tube with rings

The Skywatcher Startravel 80 is an 80mm F5 achromatic refractor with a decent rack and pinnion focuser.

It comes complete with tube rings and makes an excellent little guidescope or travel rich field telescope.

Altair Lightwave 80mm ED Doublet

The Altair Lightwave 80mm F6.25 is a portable ED refractor for imaging and visual use. The doublet F6.25 ED optics feature a Synthetic Fluorite Ohara FPL53 ED element for very good colour correction and high contrast images. Colour aberrations are almost invisible with well corrected eyepieces even on bright objects at high power. For terrestrial spotting use, this multi-purpose instrument outperforms spotting scopes costing up to 4x the price with ease when an astro eyepiece is used. The design objective was to keep weight low for portability, while adding a rack and pinion focuser, tube rings, and a proper, rigid, imaging compatible interface for CCD and DSLR camera users. This product combines all the features our customers have been asking for, and then some.

Several features make the Altair Lightwave 80mm F6.25 solid choice for imaging or visual use. The dual speed rack and pinion focuser with a 1:10 ratio fine adjustment knob makes accurate focusing easy. That means sharp images at the eyepiece, or on your camera CCD chip (focusing is especially easy in "live view mode" on a DSLR). 8x steel roller bearings support the focuser tube along it's length, making the focuser more rigid than focusers of comparable size, while keeping the overall optical tube as light as possible. A rack 'n pinion gear improves the "lifting power" of the focuser, making it similar to a large Crayford, but keeping weight and size down to fulfill the portability requirement. Proper tube rings grip the optical tube, with a standard M6 hole spacing. This enables use of the Altair TMS 180 Vixen-format dovetail bar so you can mount this telescope side-by-side, or "piggyback" it on another telescope with a solid connection. By allowing the use of a proper tube ring / dovetail bar system, the whole system is more rigid compared to designs using an L-Shaped foot attached to the focuser by one bolt. With dual tube rings, the telescope is supported along it's length, allowing easier balancing. The included aluminium-finish carry case is padded with protective foam, and protects the scope for travel.

Adapters: The rear of the focuser sports a M54x0.75mm thread, enabling direct connection of several cameras and filter wheels and keeping the aperture as clear as possible. The telescope includes an M54x0.75mm to standard 2" push-fit adapter enabling the use of standard astro 2" eyepieces and diagonals. What's more, the adapter has 3x clamping screws (one thumbscrew and two slotted) with 120 degree separation, to ensure a rigid connection and a tight grip on your visual or imaging accessories. To make the system even more compatible with modern imaging equipment, an optional M54x0.75mm to M48x0.75mm (e.g. Standard filter thread) adapter is also available. This lets you screw the Altair M48 variable spacer system directly to the focuser, to connect M48 CCD cameras, filter wheels and field flatteners, or your digital SLR via any standard M48 DSLR camera adapter.

Mounts: For imaging, this telescope enables you to use a very light weight mount indeed so just about any mount from about EQ5 size upwards will do, and unguided exposures are possible provided you polar align accurately. For visual use or solar observing, this telescope is an ideal companion for the iOptron Cube PRO and this would be an airline portable package similar in size to a medium camera zoom lens.

Technical Specs:

80mm Doublet, Ohara Synthetic Fluorite FPL-53 ED lens, 500mm focal length.
Max practical power 160x (approx.)
540mm folded length, weight 3kg (approx.)
Dual Speed 1:10 ratio “Rack ‘n Pinion” focuser with internal baffling.
M54x0.75mm rear thread > 2” push-fit adapter with 3x clamping screws and brass compression ring included.
Alu-finish case with foam padding.
Optional M48 male-thread imaging adapter, compatible with Altair M48 variable spacers or a DSLR M48 adapter.
2x Tube rings, enabling use of a proper Vixen-format dovetail bar for maximum compatibility with mounts, and a very short fold-down length for travel.
