With StarSense Explorer, locating objects has never been easier, faster, or more accurate. Within minutes of setting up the telescope, you’ll be navigating the sky with confidence. Simply place your phone in the unique StarSense dock and launch the StarSense Explorer app. After aligning your phone to the telescope’s optics (a quick, 2-minute procedure), StarSense Explorer generates a list of celestial objects currently visible. Make your selection and arrows appear onscreen, guiding you as you to move the telescope.

The base has a standard 3-in-line hole pattern allowing attachment to most mounting systems on the market or to a camera tripod using  M6 or 1\/4\" Photo Tripod Screws.

The contrast is very good enabling you to see a jovian moon against the brightly lit background of Jupiter. Saturn's rings and Cassini division are easy to see at higher magnifications and cloud bands are visible on Saturn as well as the polar caps. Mars shows surface features and polar caps easily. Thousands of craters are visible on the moon - enough for a lifetime of observation.

When compared to small Achromatic refractors of similar size, length and focal ratio, the Starwave 80ED offers better mechanics for easier focusing, and truer colour rendition thanks to the ED optics. The Starwave 80 ED delivers a sharp \"contrasty\" image with good colour correction and tight star images. The 80mm aperture gathers about 131 times more light than the human eye, and in a dark-sky location, observation of star clouds and larger more extended objects is most enjoyable. With a higher power eyepiece or Barlow lens, this telescope will show the planetary disc of Jupiter, the Great Red Spot, and the major cloud bands visible as irregular stripes across the disc, as well as the four largest Galilean moons and their movements from hour-to-hour. Saturn's rings and Cassini division are easy to see at higher magnifications. \u003c\/p\u003e\r\n\u003c\/div\u003e\r\n\u003cdiv\u003e \u003c\/div\u003e\r\n\u003cdiv\u003eThe convenience of a refractor. This is the perfect scope to get you, family and friends familiar with the night-sky, or started in astro-photography. Unlike most starter-telescopes, both optical and mechanical quality are very good. We don't sacrifice one for the other. Our philosophy is not to start with low quality equipment, but to include high quality optics in a beginner telescope at a good price to make using the product enjoyable. The Starwave 80 ED is an ideal beginner's choice for astrophotography with your DSLR or Altair camera. It is much easier to use than a Newtonian reflector, with a smaller tube which is easier to mount and keep steady. Unlike reflectors, the optics do not require frequent collimation (alignment) before use, so the product is virtually maintenance free aside from the usual yearly cleaning of the lens. For visual observerving, the Starwave 80ED fits almost any telescope mount.

The optics are compatible with the Lightwave 0.8x field flattener \/ reducer and the Lightwave 1.0x field flattener which have a T-Thread to connect to DSLR adapters. These are positioned at approx. 55mm from the rear flat face of the reducer\/flattener to the camera sensor. The machined aluminium tube transmits heat to the optics, which benefits users of dew control systems. It also allows the optics to shed heat rapidly for fast cool-down to the ambient temperature - a must for best performance with any telescope.

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.\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\u003cdiv\u003e \u003c\/div\u003e\r\n\u003cdiv\u003eThe 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.

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. \u003cstrong\u003eA laser interferometer image in 532nm green light is included with your telescope.\u003c\/strong\u003e 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.\u003c\/div\u003e\r\n\u003cdiv\u003e \u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\u003cdiv\u003eThe optional \u003cstrong\u003eAltair PLANOSTAR 3\" Field Flattener\u003c\/strong\u003e 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.

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 \u003cstrong\u003e optional Altair 60mm Miniguider\u003c\/strong\u003e 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.

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. \u003cem\u003ePlease note\u003c\/em\u003e, 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.\u003c\/div\u003e\r\n\u003cdiv\u003e \u003c\/div\u003e\r\n\u003cdiv\u003eWhat can I expect to see with the Altair 102-805 EDT APO telescope, and how does it compare to the Altair 115 APO visually?\u003c\/div\u003e\r\n\u003cdiv\u003eThis 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.\u003c\/div\u003e\r\n\u003cdiv\u003e \u003c\/div\u003e\r\n\u003cdiv\u003eWhat magnification will eyepieces produce?\u003c\/div\u003e\r\n\u003cdiv\u003eAs an example, the following common eyepiece focal lengths will give the following magnification:\u003c\/div\u003e\r\n\u003cdiv\u003e \u003c\/div\u003e\r\n\u003cdiv align=\"center\"\u003e\r\n\u003ctable border=\"0\" width=\"135\" cellspacing=\"0\" cellpadding=\"0\"\u003e\n\u003ccolgroup\u003e\n\u003ccol width=\"71\"\u003e\n\u003ccol width=\"64\"\u003e\n\u003c\/colgroup\u003e\r\n\u003ctbody\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl64\" width=\"71\" height=\"20\"\u003e\r\n\u003cdiv\u003eEyepiece:\u003c\/div\u003e\r\n\u003c\/td\u003e\r\n\u003ctd class=\"xl64\" width=\"64\"\u003ePower:\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl63\" height=\"20\"\u003e31mm\u003c\/td\u003e\r\n\u003ctd class=\"xl65\"\u003e23x\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl63\" height=\"20\"\u003e24mm\u003c\/td\u003e\r\n\u003ctd class=\"xl65\"\u003e30x\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl63\" height=\"20\"\u003e19mm\u003c\/td\u003e\r\n\u003ctd class=\"xl65\"\u003e38x\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl63\" height=\"20\"\u003e15mm\u003c\/td\u003e\r\n\u003ctd class=\"xl65\"\u003e48x\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl63\" height=\"20\"\u003e11mm\u003c\/td\u003e\r\n\u003ctd class=\"xl65\"\u003e65x\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl63\" height=\"20\"\u003e9mm\u003c\/td\u003e\r\n\u003ctd class=\"xl65\"\u003e79x\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl63\" height=\"20\"\u003e4mm\u003c\/td\u003e\r\n\u003ctd class=\"xl65\"\u003e179x\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003c\/tbody\u003e\r\n\u003c\/table\u003e\r\n\u003c\/div\u003e\r\n\u003cdiv\u003e \u003c\/div\u003e\r\n\u003cdiv\u003eI need a mount for this telescope, what do you recommend?

The best quality Japanese glass is used, which is fully annealed and cooled over several days to relieve internal stresses. Each lens cell has a serial number engraved on the front ring. All Wave Series lenses go through a unique quality assurance process, to ensure the highest quality and lowest chromatic aberration. Altair Astro first used this approach in 2010 with the Wave Series telescopes and our optical contractors have a fully bedded-in process. The lenses are first tested on original test-plates to ensure conformance to the correct curvatures, then adjusted in both rotation, centring and spacing. Of course we start off with far superior lenses to the \"normal\" production quality lenses offered by most manufacturers, using the original test plates. Star tests speak for themselves, and colour aberration is not visible, as can be seen from the various observing reports and images taken with Wave Series refractors over the last 11 or so years. Blue stars show negligible bloat in long exposure images, because the blue channel is particularly well controlled, making this telescope ideal for astrophotography. Astigmatism and Coma are included in the test report output and the test is conducted in green light. Each fringe image is a \"snapshot in time\" of the lens on the test bench. Air currents and other environmental factors can influence the image and the outcome of the report slightly, but steps are taken to minimise these during testing. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eOptional \u003c\/strong\u003e\u003cstrong\u003eAltair Planostar 0.8x 3\" Reducer Field Flattener\u003c\/strong\u003e converts your Wave Series telescope into a fast F5.6 focal ratio astrograph enabling use of astro cameras.

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.

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. Because there are more optical surfaces and materials involved, a triplet APO triplet refractor costs more than a comparable ED doublet or \"semi-APO\" - as well as reflectors of similar aperture. An additional advantage is that you get a wide-field view and a high power view in one package, offering more flexibility than Cassegrain designs.\u003cbr\u003e \u003cbr\u003e\u003cstrong\u003eWhat can I expect to see with this telescope?\u003c\/strong\u003e\u003cbr\u003eThe Altair Wave Series 115mm 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. 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 so much detail that is isn't worth going into here, suffice to say that you could spend many hours watching the sun rise over crater walls, Lava plains, impact craters and mountain ranges. In terms of deep-sky objects the 115mm 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 giving it a 3D effect, as well as the dust lane in the Andromeda galaxy quite easily. The Ring nebula in Lyra is also presented a nice target and a blue\/green colour cast was quite visible.
