LUNT CAA-RF 0.8x reducer/field-flattener for nighttime photography with LS80MT, LS100MT & LS130MT telescopes

Modular designed multipurpose telescope, both for observing the sun in the H-alpha wavelength, as well as for night sky observations. Easy conversion between the different applications with a few simple steps. Excellent image quality due to 2-lens ED optics with 70mm aperture for night sky observation, and 60mm usable aperture for H-alpha solar observation.With innovative air pressure tuning system, high-quality 2 inch (50.8mm) Rack&Pinion (R&P) focuser, and B600 blocking filter.Solar observing in H-alpha:The LS60MT/B600 is a complete telescope for observing the sun in H-alpha light, with 60mm free aperture (no central obstruction) and 420mm focal length. The H-alpha wavelength is the most impressive way to observe the sun, showing protuberances at the sun's edge, filaments and flares on the surface, and much more. An internal Etalon filter achieves a bandwidth of <0.7 Angstrom with the innovative air pressure tuning system Pressure-Tuner. Tuning is done by slightly changing the air pressure in a pressure chamber inside the telescope. This changes the refractive index of the air, making it easy to tune to the H-alpha line. The pressure tuner guarantees a homogeneous image, without central obstruction, and a permanently protected Etalon without erosion. A set of collimating lenses installed in the telescope ensures best performance.Fine adjustment is achieved with a solid 2 inch Rack&Pinion focuser with 10:1 reduction.Blocking-filter is the B600. The B600 is good for visual solar observing. Also solar imaging is possible by cameras with small CCD chip. We recommend a LS60MT with B1200 blocking-filter by using cameras with middle or large sized CCD chips.The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25 inch eyepieces and with a T2 camera connection.Observing the starry night sky:The H-alpha Etalon system can be removed from the telescope in a few easy steps thanks to its modular design. The 2-lens ED refractor can then be used as a normal telescope with 70mm aperture and 420mm focal length for observation and photography of the night sky. The ED Doublet lens will offer an excellent image. It can be used with a standard 2 inch zenith mirror at the R&P focuser.With an additional Amici prism, the telescope can of course also be used during the day for nature and landscape observations.This makes the LS60MT, with its small dimensions and low weight, also an ideal travel telescope for all applications!More applications:With additionally available accessories the LS60MT offers even more possibilities!- Double-StackThe LS60MT telescope can optionally be upgraded with the additionally available double-stack filters LS50FHa or LS60FHa (part numbers 0550200 and 0550250). These filters will be simply screwed on the front of the LS60MT, no additional adapters are necessary. Thereby a bandwidth of <0.5 Angstrom is achieved for H-alpha solar observation. Therefore much more details on the solar surface will become visible.- Solar observing in White-LightIf the H-alpha unit has been removed, of course either a sun filter to be installed in front of the objective, or a Herschel-wedge at the focuser can be used to observe the sunspots in White-Light.- Solar observing in Ca-K wavelengthCertainly, the Ca-K filter modules from Lunt Solar Systems can also be used at the LS60MT to observe and photograph super-granulation and other effects visible in this wavelength on the sun.This makes the LS60MT a completely universal usable telescope!FEATURES2-lens ED refractor, FPL-51Aperture: 70mmUsable aperture in H-alpha: 60mm (no central obstruction)Focal length: 420mmBandwidth: internal Etalon with <0.7 AngstromTuning: air pressure tuning system Pressure-TunerBlocking filter: B600 with 1.25 inch and T2 connectionFocuser: Rack&Pinion focuser with 10:1 reductionTube-ring with 1/4-20 tapped base (standard thread for photo-tripods)Weight with H-alpha unit: 3.8kgWeight without H-alpha unit: 2.6kgLength with H-alpha unit and blocking filter: 40cmLength without H-alpha unit: 31cmSCOPE OF DELIVERYLS60MT Multipurpose TelescopePressure-TunerB600 blocking filter in star-diagonal housing2 inch Rack&Pinion focuserTube ring with 1/4-20 connection for mounting on photo-tripodsTransport case (53x33x17cm)Instruction manual

The BRESSER Venus 76/700 AZ reflecting telescope allows beginners to experience their very own stargazing hours quickly and easily. With the complete set, you are equipped with everything you need for your very own sky observations: an astronomical reflecting telescope with 76 mm aperture and 700 mm focal length, an azimuthal mount, a tripod as well as extensive accessories. And to guarantee a successful start in astronomy, the system is very easy to handle – the perfect first telescope for beginners! Established technology for your easy start – the telescope With this entry-level telescope, you will be able to admire the night sky through a classic Newtonian reflector. A little surprising for astronomy novices: with this particular type, you do not look in at the back of the telescope, but at the front and laterally. The advantage: even if the telescope aperture is directed vertically towards the sky, you can make your discoveries very comfortably. No need to bend down! In addition, the Newtonian reflector is very easy to use. The optics in this type of reflector telescopes are also impressive, because they are free of chromatic aberrations – resulting in good imaging properties at all times. A sharp image with good contrast – the Venus reflector telescope achieves this with its large focal ratio of about 1 to 9.2 (F/9.2 – calculated from 76 mm aperture and 700 mm focal length). Thanks to its long focal length, the telescope for beginners shows you the Moon, Sun, planets, open star clusters as well as globular clusters in a particularly impressive way. And all this at a magnification of up to 150x in really sharp images! Technically, you can magnify even higher – theoretically up to 525x while using the included accessories. However, as the magnification increases, the sharpness of the image may slowly decrease. Of course, how much you can magnify depends not only on the resolving power of your telescope. The air turbulence in the atmosphere (seeing conditions) also plays an important role. Note for nature lovers: If you choose a Newtonian telescope like the Venus reflector telescope, you can look forward to a specialist in astronomical observation. However, the image is always displayed laterally reversed as well as upside down, which makes no difference when observing the sky. However, this type of telescope is less suitable for nature and landscape observation during the day. Would you like to use your new telescope for exciting nature discoveries as well? Then we recommend that you choose one of the BRESSER refractor telescopes. A good foundation for a successful start – mount and tripod The height-adjustable aluminium tripod and the azimuthal mount provide a firm footing and easy celestial navigation. Especially the azimuthal mount makes life easy for beginners, because it is very user-friendly: just like a typical photo tripod, you turn the telescope by hand to the left and right, up and down. This way, your favourite celestial objects quickly appear in your field of vision. Handy: to ensure that your astronomy accessories are always within reach, there is a storage plate between the tripod legs. Everything that goes with it – the accessories Out of the box straight to the fun of observing – with the complete astronomy set, you are quickly on your way to discovering the universe. The LED viewfinder helps you keep an eye on the sky. You just mount the direction finder parallel to the actual telescope and it projects a red dot onto a small ground-glass screen. This then appears to be hovering in front of the sky when you look through the viewfinder. And it does so at exactly the same spot that your telescope is pointed at. This way, the LED finder helps you to align the reflector telescope precisely and to find the celestial objects more easily. When it comes to the level of detail in your observations, the Venus beginner's reflector telescope gives you a choice: the two included eyepieces (4 mm and 20 mm) allow you two different magnifications. You want to get an even closer look? Then simply triple the magnification of the eyepieces with the 3x Barlow lens. In addition, the socket diameter of 31.7 mm (1.25 inch) complies with an international and manufacturer-independent standard. So you can easily expand your set – and with it your astronomical horizon. If you want to observe fascinating sights not only at night but also during the day, simply grab the solar filter. With it, you can safely admire spots and granulation on our nearest star – the Sun. CAUTION: Never point the telescope at the Sun without the solar filter! A new hobby leads to new impressions – and naturally you want to capture and share those. Therefore, you can easily use your mobile phone for your first steps into astrophotograpy with the smartphone adapter. Perfect for great snapshots of the Moon or the Sun, for example. Look forward to exciting astronomical discoveries by day and night – with the BRESSER Venus 76/700 AZ reflector telescope.

Maksutov Newton MN-152 David H. Levy Comet Hunter Telescope Highly corrected optic for wide-field observation and astrophotography. Developed in collaboration with the famous "comet hunter" David H. Levy. The Maksutov-Newton system does have some pros and cons respectively to the classical newtonian design. Apart from the higher price the main disadvantage is the higher weight - the thick corrector lens at the front is the cause for this. The main advantage of the Maksutov-Newton compared to the classical newton is the sharpness of the field of view. Classical newtonian telescopes do show a sharp pinpoint star image only at the middle of the field of view - outside the optical axis they have a dominant abberation, the so called coma. This is inherent in the newtonian design, and therefore valid for all newtonian telescopes of all brands and not caused by manufacturing tolerances. Coma distorts the star image - the pinpoint star shows a tail, just like a small comet. This decreases sharpness and contrast considerably. The Maksutov-Newton shows a much sharper star image - for most applications the coma is not visible. This results in a high contrast image all over the field of view - for visual observations and for astrophotography with DSLRs alike. This makes the Maksutov-Newton a ideal all-purpose telescope, that is able to show a sharp field without the need for additional correctors.
