Ioptron ZEQ25 Equatorial Mounting

The ZEQ25GT is a new equatorial mount product from iOptron designed for imaging and visual observing, it sits between the IEQ30 and the SmartEQ PRO in carrying capacity and size, with a unique and innovative design.

The ZEQ25GT offers one of the most sophisticated electronic/mechanical packages on the market today in a smaller sized equatorial mount, with all the features you need to start imaging in the field quickly and easily.

The new iOptron "Z" design mount puts the weight of the payload at the center of gravity allowing for greater natural stability. Given its payload capacity, this means the "Z" designed mount is unusually light-a nice benefit when setting up at a remote site. Other features include an adjustable counterweight bar to prevent obstruction with the tripod. And polar aligning is quick and accessible all the time since the polar scope is not blocked by the declination shaft this design is known as the CEM or Chinese Equatorial Mount.

The ZEQ25GT is equipped with the most advanced GOTONOVA® GOTO technology, making it one of the most powerful and accurate GOTO mounts available. Its database includes over 59,000 objects-its Go2Nova® Hand Controller is intuitive to use and its large 4-line LCD screen simplifies the process of setting telescopes and locating objects. The ZEQ25 - a new category of viewing and astrophotography.

Altair Astro DeepField -250 Corrected Ritchey Chretien Telescope

A 10" F8 carbon fibre truss tube Ritchey Chretien astrograph, 100% designed and manufactured in UK/Europe, to the highest specification.

The Altair DeepField Ritchey Chretien design is a professional observatory grade imaging instrument, suitable for schools, colleges and universities, or advanced amateur astronomers who want the best quality on the market. The complete design has taken over a year to complete and test, having been through two iterations.

Altair have chosen a truss-tube design because of the better thermal characteristics afforded by air circulation around the optics, almost eliminating the contrast-robbing effects of boundary air current layer formation, as well as allowing the optics to come to thermal equilibrium faster. This is also an extremely rigid design, which ensures optimum performance for the most demanding imaging requirements.

The two-element field flattener is dedicated to the particular spherical correction of the Altair Deepfield optical design at this particular aperture and is made in Europe in the same optical laboratory responsible for the mirror polishing and figuring.

Each optical set is generated and polished as a set and tested several times on a laser interferometry system, before coating in aluminium with a silicon dioxide overcoat. Each telescope comes with an optical test report which takes both primary and secondary mirrors into account as a complete system.

"Altair Astro DeepField Ritchey Chretien telescope optics are tested many times during production. The wave-front error of the complete optical system (consisting of both primary and secondary mirror as a set) must meet a minimum standard of at least 0.94 Strehl Ratio when exiting the focuser but without flattener). Each telescope is shipped with a screen-shot showing the final interferometric analysis of the wave-front produced by the particular set of optics in the telescope. This screenshot includes a computer-analysis of the wave-front produced on the test bench. Please note, in the interests of accuracy, astigmatism and coma values are not suppressed on the optical test report. Interferogram results can vary slightly with alignment of the optics when tested, ambient vibrations in the laboratory, and with random air currents - though precautions are of course taken to minimise these factors just as in any optical laboratory. The test report is to be treated like a photographic record, and each test report is unique to your telescope."

This is a special-order product. The December 2012 production run is already allocated, however more optical sets are in production which will be ready in February 2013. For more information, or for a special quote including camera, pier, observatory or robotic mount, please get in touch.

Altair-GSO 8" F8 Metal Tubed Ritchey Chretien OTA

This is a "fully loaded" version of the tried and tested 8" F8 Metal-Tube Ritchey-Chrétien with the following features:

A 2" Dual Speed Linear Bearing Focuser included as standard. It will handle a DSLR or CCD camera, and a light weight filter wheel perfectly well, and is adequate in most imaging situations. Note this focuser has the Linear Bearing upgrade, and will outperform most Taiwanese dual speed focusers, both in rigidity and pulling power. It is perfectly adequate for a DSLR/CCD camera and light weight filter wheel.

A Losmandy format dovetail plate and Vixen format bar are included, attached to the top and bottom of the optical tube.

You can now use one or more Altair TMS Vixen or Losmandy clamps clamps upside down (depending on the top bar type), to attach the rings to the underside and adjust the ring spacing to fit your guide scope without having to buy an additional dovetail plate. A small guide scope is perfect for this.

3x Heavy Duty Extension tubes included (2x 25mm & 1x 50mm) fitting between the focuser and the telescope. CNC Machined out of solid billet aluminium, zero flex.

Low expansion Quartz Mirrors with 96% reflective enhanced aluminium coatings with a Quartz overcoat (Silicon dioxide).
8" aperture true hyperboloid Primary & Secondary Mirrors.

Multiple internal light baffles line the optical tube.

Fast efficient cool down time compared to a normal
SCT due to the open-tube design.

This telescope is designed with enough backfocus to use an off axis guider, AO unit and filter wheel. Therefore, to create the most rigid imaging train possible, instead of placing extension tubes after the focuser it's best to place them between the focuser and the rear mirror cell. Therefore 1x 50mm and 2x 25mm large diameter extension rings are included for this purpose, which can be placed between the focuser and telescope (with zero flex), for adjusting your backfocus.

Dimensions: OTA length 455mm Outside diameter 230mm Tube weight is 7.5kgs. The central obstruction diameter is 95mm

It is perfectly adequate for a DSLR/CCD camera and light weight filter wheel.

Two Vixen/Synta format dovetail bars are included, with one on top of the scope for guide scope attachment using the Altair TMS Lightweight Guide Scope Rings. You can now use one or more Altair TMS Vixen clamps upside down, to attach the rings to the underside and adjust the ring spacing to fit your guide scope. A small guide scope is perfect for this.

Low weight of about 5.5kg makes this the ideal portable long focal length imaging scope, freeing up your mount capacity for other accessories.

High quality BK7 Mirrors with 96% reflective enhanced aluminium coatings and a Quartz overcoat (Silicon dioxide).

6" F9 true hyperboloid primary & secondary Mirrors (1370mm Focal Length).

Multiple internal light baffles line the interior of the optical tube.

Fast efficient cool down time usually twice as fast as a normal SCT or Maksutov, due to the open-tube design of the RC.

This telescope is designed with enough backfocus to use an off axis guider, AO unit and filter wheel. Therefore, to create the most rigid imaging train possible, instead of placing extension tubes after the focuser it's best to place them between the focuser and the rear mirror cell. Therefore 1x 50mm and 2x 25mm large diameter extension rings are included for this purpose, which can be placed between the focuser and telescope (with zero flex), for adjusting your backfocus.

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.

Altair TMS Heavy Duty Universal saddle Plate

**Please Note the price includes carriage**

This is a heavy duty saddle plate which is compatible with both the Vixen/Synta (far East) telescope mounting bars, or the Losmandy (USA) wide format mounting plates.

**Please Note Our Prices Include Carriage**

The Universal Saddle Plate or "USP" is also compatible with the rest of the blue anodised Altair TMS Telescope Mounting System accessory range.

Altair Heavy Duty USP Features:

•Compatible with Far East and US telescope mounts, including iOptron Minitower with the appropriate adapter. The most compatible and modular system on the market bar none.

•Safe and easy "tip in" saddle lets you place your telescope quickly and easily while tightening up the clamps with your other hand. This avoids that awkward struggle in the dark, while you try to hold onto a damp slippery telescope, while carefully lining up a saddle plate which will only go in from the end. Based on feedback and requests from several customers who have nearly dropped their telescopes!

•Chamfered edges to make it even easier to get a heavy telescope placed securely, before tightening the clamps with your other hand.

•Heavy duty hard anodised star knobs, custom-machined for a positive grip (we tested several iterations).

•2x Heavy duty spring loaded clamps with Stainless Steel M8 threads (unlike cheap chromed, or zinc plated threads which corrode after a few months as the coating flakes away).

•Looks great in hard anodised "Altair Blue" to match the rest of the TMS range. What's more, we haven't compromised on quality, function dictates form, not the other way round.

•No sharp edges or poor machining.

•The clamp has it's own machined guides, unlike inferior makes where the thread alone takes most of the strain.

•The right level of quality at the right price - try adding up everything you need and bearing versatility in mind when comparing to other makes.

•Readily available and made locally in the UK at our machine shop on HAAS 4 axis CNC milling machines. That means we have complete control over quality.

Mount compatibility:

•The Altair USP bolts directly to the Losmandy G11, replacing the factory saddle plate, a very popular upgrade.
•With the addition of an Altair TMS Equatorial mount adapter puck, the USP-2 will also fit the Synta/Skywatcher/Orion USA EQ6, H-EQ5 and EQ5 mounts too.
•It also has a pair of standard M8 "Takahashi" style holes on the base with 35mm separation, enabling the Universal Saddle Plate to be mounted on the William Optics Easytouch and numerous other mounts, including Takahashi with the appropriate Tak adapter puck.
