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.

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

Remember this product includes 3x extension tubes and 2x Losmandy plates top and bottom.
This is a "fully loaded" version of the tried and tested 6" F9 Ritchey-Chrétien with the following features:
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.

Here's an autoguiding package for customers who want a quality flex-free autoguider system, with a larger aperture than our very popular Altair Miniguider 60.
This will suit scopes with a focal length of around 2 metres or more, and is suitable as a "video finder" too. A very rigid set of Altair light weight guide scope rings carries the light-weight 80mm F4.1 guide scope optical tube assembly.
The Altair Maxiguider 80 Guide-Scope Package consists of the following:
- 80mm F4.1 achromat optical tube assembly with dew-shield and objective cap.
- 1.25" Lockable Auto-guider Focuser Adapter with 3x clamping screws.
- Altair 100mm Ultralight Guide Scope Rings (GSR-100).
- Altair 180mm Vixen Dovetail Bar (VDB-CL-180).
- 4x stainless steel screws to attach the GSR100 to the Dovetail bar.
- a 1.25" RACI diagonal with helical focuser (suitable for use with a 1.25" eyepiece).
You can choose black anodized Guide Scope Rings and corresponding 180mm Vixen format dovetail bar instead of the default silver, from the options list below.

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.
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.

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.
•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.

•The Altair TMS "Vixen - Synta" Dovetail Bar is available in two different lengths of 170mm (VDB-170) and 250mm (VDB-250).
•These Far East style dovetail bars are narrow and light and are a good option for small optical tubes.
•A countersunk M6 hole at each end, plus a countersunk M6 slot, allows maximum flexibility for attachment to most telescope tube rings.
•To mount lighter telescope tubes side by side, we recommend the Altair TMS "Small Vixen Dovetail Clamp" which is designed to fit onto either end of our Losmandy plates directly, letting you mount two telescopes side by side.
•All Altair TMS components are CNC machined in aluminium and hard-anodised in Altair Blue to match the rest of the TMS range.
The Altair MiniGuider System is based on the very popular Altair 60mm Finder. The package includes a 60mm finder optical tube assembly, a special focuser for Autoguiders and Webcams, finder rings, universal bracket and stalk.
The autoguider focuser is available separately as an upgrade for customers who already have the Altair 60mm Finder, and who would like to use it for autoguiding with a webcam or autoguider head such as the QHY5, Orion USA Starshoot, or any other autoguider with a 1.25" barrel.
The product is designed to provide you with a stable platform to attach your autoguider or webcam, having to use a separate telescope. Any webcam or autoguider with a 1.25" barrel will fit. The package is ideal for astro-imagers who have a wide field portable imaging system and will work well with telescopes up to 1 metre focal length. This product is ideal for smaller capacity EQ mounts - by keeping weight down, you're putting less demand on your mount, and therefore tracking accuracy is improved.
The Webcam focuser can be rotated 360°. The 60mm objective has a focal ratio of f3.75 and a focal length of 225mm. The fast focal ratio objective is the same as found in the Altair 60mm finder, and the Mini-Guider focuser can be purchased separately, or together with an Altair finder system.
The included quick-release finder base has 4x 4mm slotted holes allowing you to fit it to most telescopes on the market. The mini-dovetail wedge on the bracket will actually fit any GSO or Skywatcher telescope directly, but we suggest you use this included base because it has 2x clamping screws, for far better rigidity than standard finder bases on the market.
The adjustable tube rings are light, yet more than rigid enough to stay in perfect alignment for autoguiding. They cannot rotate like other cheaper makes because the dovetail bar they sit upon has a slight channel to accept their profile. Nylon tipped screws avoid scratching the durable high quality and moisture resistant paint on the 60mm aluminium OTA.
All objective lenses are anti-reflection coated and the tube and dewshield are internally blackened to increase contrast. This is a high quality F3.75 achromat objective, and it will deliver pinpoint stars on your finder chip on axis, performing at the resolution limit of a 60mm lens. It is far higher quality than the lenses found in cheaper, and smaller finders, and will perform extremely well at this fast focal ratio, keeping your exposure times short, and stars very bright with a small dot size - exactly what's needed for precision autoguiding.
The new iEQ45 2013 version with Field Tripod.
Initially, the iEQ45 v1 & 2 mount was aimed at the imaging enthusiast. Light-weight, high capacity, and fast easy setup with GPS polar alignment assistance made it a great mount for visual observers too - but it was always purely an equatorial mount until now.
What's new? The new iEQ45 2013 retains all these features, however, it can be used with an optional Azimuth Base Adapter (#8050) in Alt-Azimuth Mode for visual observing or planetary webcam imaging and astro-video. This makes it extremely versatile and convenient because in Alt-Azimuth Mode, polar alignment is not necessary. That makes it even quicker and easier to start an observing session, using the accurate GOTO system to find thousands of objects in the night sky, and keeing them in the field of view at high power for many hours.
Equatorial Mode and imaging: Equatorial Mode is of course best for long exposure imaging because there is no rotation of the star-field over time. In Equatorial Mode, the iEQ45-2013 remains a very quick mount to set up in the field, because it has an very accurate polar alignment scope, with built-in GPS to improve polar alignment and GOTO accuracy. A display on the hand controller shows you where to place the pole star within the illuminated polar scope reticule for greater precision.
Converting from Equatorial-Mode to Alt-Azimuth Mode: You can convert your iEQ45-2013 EQ mount to Alt-Azimuth Mode with the optional AZ Base (product code #8050) if you prefer visual observing this way, and back Equatorial Mode again for example if you want to take long exposure deep-sky images.
Mounting a second telescope in AZ Mode: When operating in Alt-Azimuth Mode, you can even mount an additional telescope where the counterweight shaft usually goes. You can observe using two telescopes in this way! For example, a small wide-field refractor and a longer focal length scope can be used in tandem. To add a second scope in Alt-Azimuth Mode, simply remove the counterweight shaft and replace it with the optional iEQ45 Secondary Dovetail Saddle/Shaft (product code #8055). This includes a dovetail clamp which accepts both the wider 3.0" US-Style dovetail plate or the narrower 1.75" 1.75" Japanese format dovetail bars for maximum compatibility.
Optional light weight field pier: The lightweight, yet extremely rigid iOptron portable pier is also available separately. The pier legs and steel tensioning rods fit into the hollow pier cylinder for easy transport as a single unit. The pier legs are adjustable for levelling.
Weight and portability: The iEQ45 is the lightest mount in it's price range, and it's very easy to carry. The head weight (heaviest component) is only 9.7kg! The iEQ45 weighs less than half other mounts with the same carrying capacity. This is probably the best ratio on the market for a mount in this price range. (Please note, the stated capacity does not include the supplied counterweights, which weigh an additional 22lb. If you load the mount to it's 45lb maximum capacity, you'll need to balance it with approx. 45lb counterweights, in which case the mount will be carrying about 90lb total weight).
PC remote software control: Aside from the GPS and Polar Alignment asistance features, PC control is possible using planetarium software. For accurate autoguiding, an ST4 port is provided. The mount can record Periodic Error Correction data from 3rd party software to play it back and improve tracking accuracy even more. The brightness adjustable multi-line display hand control module is extremely easy-to-use, and contains an enormous 130,000 object database.
The iEQ45 is one of the most anticipated products, particulary amongst the astro-imaging community, and customers have captured some excellent long exposure images.

The RC design is a true reflective design with no refractive optical elements. As such it provides superb light transmission.
The coma free field of this standard RC delivers wide flatfield performance on cameras up to the APS sized DSLR sensors.
Full format cameras require an optional corrector to achieve flat field performance.
Click here to read a review on the 10" RC
The scope features a fixed primary and secondary mirror for flex free imaging. Included is a set of 3 thread on extension tubes to enable you to place your camera at the correct back focus distance for optimal performance. These thread between the scope and the 3" focuser - again for flex free performance.
The 3" Dual Speed Crayford focuser is a big jump in strength and rigidity from the 2" models and can easily accomodate DSLR and most CCD Imaging cameras.
This scope is a true Ritchey Chretien Astrograph and does not feature a full aperture corrector such as SCT and SCT design scopes.
