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.
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.

Quality 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.* Each lens cell has a serial number, guaranteeing it's originality as a genuine Altair Astro optic. Working closely with our contractors, 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 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.
The optional Altair PLANOSTAR 3" Field Flattener for astro-imaging: This 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 into the rear of the focuser by means of a special adapter (PLANOS-3-1.0-M48-RP25-ADAPT) which replaces the rear self-centering adapter. These threaded connections reduce flex in the imaging train, resulting in tighter star images, and sharper images. A conical rear adapter with an M48 rear thread is included with the flattener, and the correct spacing for Nikon or Canon EOS DSLR cameras can be obtained with the special Altair Astro low profile Canon DLSR adapter (M48DSLR-EOS), 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).
The optional Altair Planostar 0.79x 3" Reducer Field Flattener (PLANOS-3-1.0-M48) converts your Wave Series telescope into a fast F5.5 focal ratio astrograph. It attaches directly to the focuser when the 2" self centering assembly is unscrewed, and no adapter is required. (See associated products).
Optional 10x60mm deluxe right angle finder scope: A optional Altair Astro 60mm right angled deluxe finder scope is also available separately, with a machined bracket to fit the 3" focuser, a brightness adjustable red crosshair illuminator, and a wide field eyepiece with helical focuser. A 60mm finder offers significantly more light grasp than a 50mm finder and the optical quality is very high. Blackened lens edges and low reflectance multi-coatings ensure sharp, contrasty images across a very flat field, to help you find fainter objects against the night sky. The image in the finder is the right way up and orientated correctly left-to-right which means the what you see is what you get. Star charts will match up with your view through the finder, making object location much quicker and easier. Furthermore, the right angled design lets you use the finder from a more comfortable position compared to a straight-through finder. Its also now possible to order the  optional Altair 60mm Miniguider which includes our famous 60mm finder optical tube, rings and bracket with a webcam/autoguider adapter, enabling you to guide your scope with minimal weight increase and maximum portablity using the existing finder mounting point. The autoguider/webcam adapter is also available separately to retrofit to the Altair Astro 60mm finder scope if you have one already, or prefer the flexibility of a finder AND autoguider in one unit. (See associated products).
What performance improvement does the 102mm triplet ED lens offer? The Altair 102-715 APO sports a triplet air-spaced FPL-53 Super ED lens system for better colour correction than normal doublet or dual lens telescopes. This results in higher contrast, and a cleaner sharper image with no spurious colour visible at all in the image. Blue colour correction is particularly good and we rate this telescope as having the best colour correction in our current product range. The combination of a triplet ED lens system with very 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. This is why you'll hear amateur astronomers say things like " an APO punches above its weight in aperture compared to a reflector" or " this telescope gives a planetary image like only a refractor can" and so-on. Because there are more optical surfaces and materials involved, a triplet APO triplet refractor costs a lot more than a comparable doublet 2 lens design, as well as reflectors of similar aperture. Never has the statement "you get what you pay for" been more true. An additional advantage is that you get a wide-field view and a high power view in one package, offering more flexibility than an SCT or Maksutov. Please note, we aren't saying that ED Doublets, Maksutovs and reflectors are inferior designs by any means - a premium triplet refractor just offers higher performance "clear" aperture at the same size if compared directly, however it also costs more money per inch of aperture. Feel free to call or email us, to discuss which scope is best for your individual observing style.
What can I expect to see with the Altair 102-805 EDT APO telescope, and how does it compare to the Altair 115 APO visually?
This answer is similar to the corresponding one on the 115-805mm APO page, however in all cases the image brightness and resolution of the 102mm is slightly less than the 115 due to its slightly smaller aperture - however the colour correction is slightly better and of course the telescope is lighter and more portable. If it helps you decide, we feel that your decision to buy the 102-715 telescope should be based on the relative portability compared to the 115mm APO if you're a visual observer and your mount capacity if you're an imager, and these should be the overriding factors in your choice. That's simply because the optics are of a similar high standard. The Altair Wave Series 102mm APO will deliver very high contrast images of planets and the Moon. Under steady skies, you will easily be able to see detail and changing weather patterns in the cloud belts of Jupiter, the pastel shades of Saturn's planetary disc, as well as the Cassini Division in Saturn's rings, and the ring shadow on the planet's surface (or rather, clouds!). You'll be able to distinguish the changing weather patterns on Mars, as well the dusky surface features and the ice-white polar caps (seasons permitting). Remember planetary viewing is perfectly possible in the city and that light pollution will not affect your view at all. The Moon will reveal a lifetime's worth of detail - crater walls, Lava plains, impact craters and mountain ranges are all clearly visible in stark relief. For deep sky observing, the 102mm 7 performs best on the brighter Messier Objects. under dark skies, it will resolve the individual stars in globular clusters like M13 in Hercules, and you will be able to see wisps of nebulosity in objects like the Orion Nebula, as well as the dust lane in the Andromeda galaxy. The Ring nebula in Lyra is also presented a nice target and the high contrast makes it stand out against a dark background. This telescope can be used with nebula and light pollution filters to bring out even more detail.
What magnification will eyepieces produce?
As an example, the following common eyepiece focal lengths will give the following magnification:
31mm 23x
24mm 30x
19mm 38x
15mm 48x
11mm 65x
9mm 79x
4mm 179x
I need a mount for this telescope, what do you recommend? There are several options available, and we can offer a competitive package to suit your budget, as well as mounting hardware to suit your use scenario. Mounts capable of carrying this telescope are the iOptron Minitower v2 Advanced and Minitower PRO, iOptron iEQ45, Celestron / Synta CGEM, EQ5/HEQ5 or Vixen GP range. For imaging, an iOptron iEQ45, Losmandy GM8 or EQ6 are fine for this scope.

Crescent Nebula Image Altair 102 715 Super ED Triplet APO

Above is a full frame image of the Crescent nebula in Cygnus taken with the Altair 102/715 Super ED Triplet APO and Planostar field flattener by Phil Shepherd, at the Kelling Heath Starparty in Norfolk. Exposure times were 6x600s in Ha, SII & OIII wavelengths using a filter wheel, with an Starlight Xpress SXV-H16 CCD camera. Click on the image for the full resolution shot. Colour correction is excellent, and there is no false colour fringing evident whatsoever. The stars are tight, round and concentrated points of light right to the edge of the frame due to the 1.0x Altair Planostar field flattener. Even the hottest bluest stars exhibit in incredibly small blue halo - less or equal to than telescopes costing many thousands of pounds more, which shows off the blue colur correction of a well corrected FPL53 triplet Super APO. Below, another shot of the Cocoon nebula taken at Kelling Heath Starparty, using the same camera and telescope with 6x 600 second subs, one for each RGB channel combined.

* Fluorite crystal has an Abbe 94.99 number by comparison and is more inconsistent, with slightly more variation from batch-to-batch, and less stable chemical, thermal and physical properties. Flourite manufacture is also a toxic process with considerable environmental impacts so we don't tend to use it.

    I've enjoyed the views of Jupiter so much with this 102 triplet. Moon valleys and mountain shadows are so dark and sharp. Haven't taken it out of the city yet but holidays soon. Much richer views than my old orange C6 and much darker sky. Will start imaging soon having bought the flattener. Since I ordered in june the price has gone up.
  • Author: Douglas Firman
    I've been observing the Moon, Jupiter and recently Saturn on the outskirts of London with my Altair Wave 4" refractor. The optics are better than any telescope I've owned, including my 6" Maksutov reflector and its significantly sharper at the eyepiece with darker background near bright objects. Surface details on Jupiter are easier to see and whereas before only the main belts were visible I can see more between them. Saturn is also a treat with the Cassini division easily visible and very sharp.

    This telescope is small and light and I use it with my Giro 2 mount, 2x Barlow, Pentax/Altair-lightwave eyepieces and 2" diagonal.

    This has become my favourite planetary telescope, the best I've owned and its used every chance I get.
  • Author: Kevin Hill
    Having ordered in early January and now used this scope a few times I agree with the other comments on optical quality, which is significantly better than my 8" Schmidt (which actually cost more). The image isn't as bright, but the sharpness and contrast are better for faint detail which is exactly what the Altair people explained. This telescope has a large flat field which I prefer for nebulae and clusters, especially with my Televue Delos super wide. There is no colour aberration in or outside focus and stars are perfectly white. This is the best buy I've made so far and I recommend the separate finder scope.
  • Author: Anthony Phelps
    I've owned several refractors and after doing some research decided on the Altair 102 as my primary portable refractor for general observation.

    The quality of this telescope really becomes apparent at high powers, especially when the seeing cooperates, and the star test is perfect as expected. I've had an someone in-the-know check over the provided test image and he confirmed the objective lens is essentially perfect.

    This refractor visibly outdoes another ED Fluorite APO I own with only a few millimetres difference in aperture, which cost several hundred pounds more.

    My suggestion would be to use premium eyepieces with this telescope. I'm not an astro-photographer and despite buying the flattener which is quite substantial, I haven't tried it.

    My complements to Altair from a very satisfied owner.

    My comments are similar to the others when at the eyepiece this telescope cannot be faulted.

    To add comments from an astro photography point of view I've started my first few sub frames and not only is the field completely flat (Atik 4000) but the colour correction is perfect to the edge of the field.

    From an imaging users point of view this scope cant be faulted however you will need the stronger vixen plate Altair make for imaging because the included one is a little light which to be fair they did mention on the phone. You may need to increase the focuser pressure by tightening the large hex key underneath the focuser if you have a heavier camera and filter wheel. The focuser doesnt slip so there's no need for the focuser lock and I removed that because it sticks out the bottom of the focuser and can catch on things. In fact the scope came with it pushed into the foam separately from the scope so the packing dept must be aware of this.

    The flattener screws into the focuser, and everything is screwed in after that which is a much cleverer system than using side-screws being much more stable. This and the focuser adapter are well designed for AP.

    Triplets are very desirable equipment and this ones well worth it.

    The 102 wave was recommended to me by a fellow society member, and I had high expectations having read all the hype (!). Honestly, it's the best astronomy purchase I have ever made. I could go on but you really need to try this yourself. It's better than my 6 inch schmidt on everything, planets, the moon, deepsky the lot. The stars are like little diamonds compared to fuzzy balls. Every time I use it I see more. At our club this beats the views through quite a few larger scopes. Yes you pay for it but it's worth it. Yours truly, another refractor convert!
  • Author: fred Gilliam
    Firstly this is a great scope and the reviews bear that out but what impressed me more was the service. I returned the first unit for checking because I couldn't get evenly shaped stars with the flattener. It was actually my Canon camera sensor which was at an angle. I had no idea this was possible but apparently it's quite common.

    Thanks for Altair for diagnosing the problem quickly and for returning the scope to me for free even though I offered to pay for it.

    The tilt adjuster solved the problem - even though it took a while to get things straight.

    Altair staff are nice gentlemen who bent over backwards - even when they were right all along about the fault.

    I'll be back for more excellent service. FG
