  3. Meade Series 6000 115mm f/7 ED Triplet APO OTA

    Meade Series 6000 115mm f/7 ED Triplet APO OTA

    The Meade Series 6000 115mm f/7 ED Triplet APO OTA is now available from Telescope House! Experienced observers have long known that a true triplet apochromatic refractor telescope will give near-perfect high-contrast colour-free optical performance on the night time sky. These instruments have traditionally been extremely expensive to produce and thus out of reach of most amateur astronomers. With the 5000 Series ED APO Triplet Refractors, Meade broke down this price barrier, offering exclusivity to everyone. Building on the success of the 5000 Series, Telescope House are pleased to announce Meade's 6000 Series Refractors: bigger, better and altogether more impressive than their already illustrious predecessors. Available in 80mm (f/6), 115mm and 130mm (both f/7) versions, the 6000 Series all use a precision air-spaced multi-multicoated ED triplet lens to ensure the very finest in image quality and resolution. The 80mm 6000 Series utilises the high-grade fluorite-based FPL53 glass in its lens construction whereas the 115mm and 130mm use FK61 fluro-crown glass. Learn More

  5. Explore Scientific Ultra Light 16" Dobsonian GENERATION II

    Explore Scientific Ultra Light 16" Dobsonian GENERATION II

    The Explore Scientific Ultra Light 16" Dobsonian GENERATION II is the ultimate in collapsible, large aperture, portable telescopes - featuring full aluminium construction for strength, durability and lightness. This system has very easy to collimate primary and secondary mirrors, which is vital for instruments of this type. The whole telescope folds and packs down into a couple of very compact packages, the main mirror box has a hinged lid for protecting the primary in transit, but also forms an integral part of the structure of the telescope in use. Getting up and observing is a simple procedure: fit the struts and altitude bearings to the main mirror box, fit the Secondary/Focuser head to the support struts, collimate - and you're ready to observe. The Explore Scientific Ultra Light 16" Dobsonian's focuser is a buttery-smooth dual speed low profile Crayford-style/Rack and Pinion Hybrid, capable of supporting the weight of heavier 2" eyepieces and accessories. With 16" or 405mm of pure aperture available, familiar Deep Sky really come to life and a wealth of objects outside the remit of smaller instruments are all within your reach. Planetary and Lunar resolution at this aperture have to be seen to be believed! Learn More

  10. Altair Wave Series 130 F7 ED Triplet APO

    Altair Wave Series 130 F7 ED Triplet APO

    This Altair Wave Series 130 F7 ED Triplet APO is a new EW 2017 CNC Tube Version with dual speed "Rack 'n Pinion" focuser, Teflon-tipped adjustable rotator, CNC machined internal knife edge baffles, and a self centering 2" adapter. Both the Planostar 1.0x and 0.79x 3" flatteners and reducers can be attached directly to the focuser, by unscrewing the rear self centering assembly. New CNC machined tube rings, CNC machined dewshield with adjustable fit, and a longer dovetail bar are included for easier balancing. An aluminium push-fit dustcap is included for the front lens.

    The Altair Astro 130mm F7 ED Triplet APO refractor uses a 905mm 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. 
    Wave Series telescopes have rapidily gained a reputation for performance well above it's price range, especially with visual observers. This is due to a special optical testing and calibration process at the final stages of production, cluminating in the production of a laser interferogram image which is delivered with every telescope. (More info below).
    Suitable for astro imaging or visual use, this is an extremely capable telescope in all areas. The telescope is ideal for serious planetary viewing, enabling faint and subtle details to be observed in high contrast. The moon, Jupiter and Saturn are very good targets for the Wave 130. The optical tube assembly can easily be carried by the Altair Sabre, iOptron iEQ45 or Minitower portable GOTO mounts (please enquire about telescope/mount packages).

    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 of course quick thermal equalisation and relative freedom from tube currents. This is unlike carbon fibre or other non-metal composite materials which not only get brittle with age and eventually crack, but often hinder thermal equalization because they do not conduct heat away from the optics. Two lightened CNC machined tube rings give a stable mounting platform for astro photography, and a large dewshield (with improved mechanism) delays the onset of dew and keeps dust and pollen away from the objective.

    The new Rack and Pinion dual speed focuser has a smooth teflon lined rotation system, and a self-centering 2" pushfit end-cap. The end cap can be removed to attach the PlanoStar 3" 1.0x Flattener and the Planostar 3" 0.79x reducer by means of a threaded adapter. 
    Two heavy duty tube rings are provided with standard hole patterns to fit most hardware mounting systems on the market including the premium Altair TMS Losmandy-format plates and carry handles.
    We recommend the Altair Astro 60mm Deluxe Finder Scope (see associated products) which is a perfect fit (holes provided) and can double as an autoguider for imaging by adding the Altair Miniguider adapter.
    Wave Series hand-made, calibrated and tested optics:
    AtmosFringe Test Report Altair Wave Series
    The 130mm Wave Series triplet APO optics are carefully finished at the final stages of production and repeatedly tested until signed off by the optician in charge of the production run. Before anti-reflection coating, the lenses are placed on a testplate to assess the deviation from the ideal design curvature and sent back for figuring until the correct curvature is achieved. During assembly, the individual lenses are assembled in the lens cell, marked and rotated and re-centred with reference from a double pass autocollimator. Many iterations are required to get the best alignment and centering combination for each lens because there are 6 glass surfaces to deal with in the case of a triplet lens assembly. Each lens cell is tested each time a small change is made in rotation or centering, or re-spacing of the elements relative to each other. Sometimes this can result in small dust particles between the lenses which have no effect on the performance of the telescope whatsoever (because they are at the entrance pupil), but are inevitable during this iterative process. This process is used to achieve the highest quality possible for each lens. At this aperture, it is preferable to have a lens which has been adjusted for optimum performance instead of a lens which is cosmetically perfect but has not been assembled to a high standard. Each lens cell has a serial number, guaranteeing it's originality as a genuine modified Altair Astro optic. Lens numbers start afresh with each major change in production. Once the optimum setup is reached, the lens is signed off, a laser interferogram image in 532nm green light is inputted into AtmosFRINGE software to produce a test report showing the lens characteristics, which is included with each telescope. The image is a snapshot in time of the lens after assembly. Altair Astro has been performing this QC process since 2008, and no other UK company to our knowledge is capable, nor even willing to perform this level of quality control, which is the essence of the Wave Series concept. This process is labour intensive, and it can take a day or more to adjust one lens to optimum, therefore Wave Series telescopes cost a little more than other scopes of similar aperture.
