Vixen VC200L Optical tube

Featuring an improved design and optical properties, this compact field corrected Maksutov-Cassegrain system is Vixen's answer to Schmidt Cassegrain and more conventional Maksutov Telescopes. Instead of a heavy corrector plate, the Meniscus corrector is located directly in front of the secondary mirror. As a result, the Field-Maksutov does not dew up easily, as most conventional SCT s and Maksutovs do, when exposed to humid air.  Thanks to the VMC's open tube system, the optics cool down quickly, ensuring that the telescope is ready for use in no time - again offering advantages over traditional Schmidts and Maksutovs, which can take a long time to acclimatise and reach thermal equilibrium. The long focal length of the VMC allows you to make detailed observations of planets, distant galaxies, individual lunar craters and mountains and many other celestial objects.  The mirror is manufactured using an advanced coating deposition technique, normally reserved for research-grade instruments - ensuring an extremely smooth and precisely-finished optical surface.  This, combined with the secondary corrector delivers extremely pleasing visual and photographic performance, with a very flat field.  Unlike the primary mirrors in many rival SCTs and Maksutovs, the VMC200L's primary is fixed and doesn't travel on a focuser baffle, adding to stability and as a result this telescope does not suffer from "mirror flop" or focus shift.The focuser is a conventional, smooth-running single speed rack and pinion design, which ensures stability, even at high loading.  It can be simply upgraded to dual speed use for finer focus control with the X000143 Vixen Dual-Speed-Focuser, if required.The telescope is supplied with a standard Vixen profile mounting dovetail bar and is also supplied with a carry handle, which makes transport and mounting much easier.  The carry handle can also double up as a mounting platform for other accessories, if required.The VMC200L is also supplied with Vixen's superb 7x50mm illuminated finderscope, with variable brightness control, to help you guide the telescope accurately to targets.Last, but not least, is the inclusion of Vixen's extremely useful flip mirror system, which allows for mutual mounting of 1.25" eyepieces or accessories.  Both eyepiece holders can be unscrewed, revealing a standard T2 mounting thread, which allows easy mounting of many cameras or other photographic accessories to either port.  The ability to be able to flip simply between visual use and a camera is of great help when trying to centre and image compact targets - speeding up acquisition of targets and making better use of your time under the night sky.FEATURES 200 mm mirror Focal length: 1950 mm (f9.75) Resolution and limiting magnitude: 0.45 arc seconds; 13.3 Light-gathering power: 816x Backfocus without Reducer: 144.9 mmBackfocus with Reducer: 63.5 mm Dimensions and weight: 232 x 510, 6.8 kg Adapter and connections: 60 mm thread WHAT’S INCLUDED Dovetail bar Flip mirror Carry handle 7x50 viewfinder, illuminated

The optics of the VMC260L are significantly better than the traditional Schmidt-Cassegrain telescope. Despite its high 3000 mm focal length, it is just 650 mm long. Featuring a large 260 mm aperture, the telescope collects large amounts of light for serious professional observations and photography of the planets and countless deep-sky objects. Thanks to the dielectric mirrors, the VMV260L guarantees razor-sharp images and maximum brightness. The open lens barrels cool the telescope quicker than conventional closed Cassegrain systems. The telescope can be used with an optional 0.62x focal reducer to reduce the aperture ratio to 1:7.1. This shortens the exposure times and allows you to photograph large objects. The telescope comes with a standard dovetail bar and a carry handle that doubles up as a camera holder for night sky photography.

Above-average contrast The Reducer HD features the optical coating that was developed by Vixen for our high-end VSD100F3.8 astrograph. The AS coating provides light transmission of up to 99.9% per lens surface. The special matte surface in the interior also minimizes ghosting, light loss and lens flares. Reducer HD in combination with SD telescopes The Reducer HD can be used on telescopes from the SD series (SD81S, SD103S and SD113S) with the SD Flattener HD Kit (item #37246) . The Reducer HD reduces the focal length by a factor of 0.79x (f/7.7 to f/6.1) and delivers a razor sharp image over the entire 44 mm image sensor surface on DSLR cameras. Reducer HD in combination with AX103S and VC200L telescopes In addition to the SD telescopes, the Reducer SD is also compatible with the AX103S and VC200L telescopes. With these telescopes, the focal length is reduced by a factor of 0.77x.FEATURESUp to 99.9% light transmission per lens surfaceReduces the focal length by a factor of 0.79xAlso suitable for full-frame DSLR camerasFor the ED/SD 81S, 103S, 115SAS coating with light transmission of up to 99.9% DELIVERY CONTENTVixen Reducer HDDust caps

SXD2WL VC200L Cassegrain Telescope Complete Set with GoTo Mount, Tripod, and EyepiecesThis high-quality telescope set impresses with its large 200-mm Cassegrain mirror optics optimized for photography with a flattener. The telescope is manufactured in Japan and scores with its excellent workmanship, sharpness, and contrast performance. The advantage of this telescope also lies in its short, open design and its low weight. Thus, the optics cool down faster than a closed system.The VISAC primary mirror (= Vixen Sixth-Order Aspheric Cassegrain) is specially designed for astrophotography and delivers a completely flat and color-true image across the entire field of view. Spherical aberration, coma, and field curvature are absolute foreign concepts for this optic. The reason for this is the three-lens field corrector in front of the convex secondary mirror.Although the telescope is optimized for astrophotography, it can of course also be used for visual observation. A special coating technique (state-of-the-art technology) provides the optimal mirror surface for observing and photographing deep-sky objects. It allows for controlled coating and individually corrects errors on the mirrors. You will be amazed when you observe the moon's surface with its craters or Saturn with its ring system. On Jupiter, on a good night, many smaller details in the cloud bands will be visible, as well as the Great Red Spot on the planet. On moonless nights, you can observe the Andromeda Nebula, Orion Nebula, Eagle Nebula, Lagoon Nebula and many other interesting faint objects. The brighter globular clusters can be easily resolved into individual stars.This telescope set "Made in Japan" simply leaves no wishes unfulfilled. The large 60-mm eyepiece drawtube allows for the attachment of heavy cameras without tilting. In addition, the supplied flip mirror enables comfortable observation even in unfavorable observing situations and also offers a T2 thread for connecting a DSLR camera. Thus, you can observe in straight view or at a 90° angle. The carrying handle attached to the tube clamps ensures safe transport of the telescope. The sturdy metal tripod allows for a vibration-free setup of the telescope and mount even in windy weather.The SXD2WL mount is simply operated via a Wifi module with a smartphone or tablet. For user-friendly control of the mount, the free STAR BOOK Wireless app is available. This allows you to use practical functions of celestial navigation such as automatic GoTo swivelling to specific celestial objects very easily via your smartphone or tablet. As the power consumption of the conventional LCD screen (STAR BOOK TEN) is eliminated, the power consumption of the mount is reduced by up to 20%. This enables astronomical observations and astrophotography over longer periods. By tapping the desired celestial object from a list, it automatically swivels into the telescope's field of view and tracking begins. An existing STAR BOOK TEN control can also be used on this mount without any problems. Equipped with the same precision stepper motors as the flagship model, the AXD mount, the SXD2WL brings a new standard of performance and precision to the Vixen mount family. The axis cross of the mount has a photographic carrying capacity of 15 kg while weighing only 9.2 kg, making it excellent for mobile observations. Moreover, the motors located in the lower part of the mount also serve as counterweights. This means the mount requires fewer weights for balancing. Details of the SXD2 Mount Precision stepper motors and Micro-Step Motion Control System The heart of the SXD2 are the precision stepper motors, offering better performance and response than previous models. The Micro-Step Motion Control System is noted for its powerful yet very quiet driving characteristics, suitable for both fine movements and rapid swivelling. Built-in bearings The bearings of the RA and DEC axes and the worm shafts have been significantly improved to reduce the load on the motors. As a result, the motors move much more quietly than in previous models. High-precision worm gears Advanced manufacturing technologies have eliminated errors in worm gears. The edges of both the worms and worm gears are exceptionally smooth, allowing very precise tracking. Declination axis as counterweight The massive motor units are built into the lower part of the declination axis, lowering the center of gravity of the SXD2 just below the intersection point of the RA and DEC axes. This reduces the need for additional counterweights. Latitude adjustment The latitude is adjustable between 0 and 70 degrees (divided into 3 zones and adjustable +/- 15 degrees per zone, for high, medium, and low latitudes); latitude scale in 2-degree steps; fine adjustment with a tangent screw head, about 0.8 degrees per turn. Built-in PFL-II Polar Finder with Illumination The built-in 5x20 mm polar finder with a 10° field of view features a 3-star alignment system. This eliminates the tedious setting of date and time. The illuminated reticle with variable brightness and automatic shutoff is adjustable in 8 steps and illuminated in red. The alignment accuracy is 3 arc minutes. Details of the Wireless Module The Vixen Wifi Adapter for EQ mounts enables you to control your Vixen mount via a smartphone or tablet. With the STAR BOOK Wireless smartphone app (free), celestial navigation is simple and wireless. The app instantly transforms your mobile device into a control for the equatorial mount. The reaction delay of the mount, a major disadvantage of wireless connections, has been reduced to a level comparable to wired solutions. Reduced power consumption compared to traditional controls with an LCD monitor The power consumption of the mount is reduced by up to 20%, allowing for longer observations than with traditional wired controls like the STAR BOOK TEN. Operation similar to the STAR BOOK TEN control The STAR BOOK Wireless App is set up similarly to the STAR BOOK TEN control. Depending on the star chart setting, it contains up to 259,000 celestial objects. Tap a celestial object in the list and start the GoTo. The mount will now automatically move to this target and bring it into the field of view of the telescope. All popular features of the STAR BOOK TEN are retained. Convenient operation While looking through the telescope, you operate the mount by swiping on the star chart in the app. Since there are no buttons, you simply glide your finger across the star chart to easily operate the mount. Extensive astronomical data included This includes data on easily observable celestial bodies such as Messier objects, NGC objects, IC objects, as well as the sun, moon, planets, comets, and dwarf planets. High-precision alignment Alignment on one or two stars already provides a fairly accurate positioning of the mount. Alignment on three or more stars allows for extremely precise alignment of the mount for high magnifications. The objects are then positioned exactly and centrally in the field of view of your telescope. The alignment information is stored and can also be retained when the device is turned off. By leaving the telescope in its current state after an observation, without moving it, you can start the next observation with the same settings. Individual adjustment options As with the STAR BOOK TEN control, the app offers various individual settings such as gear play compensation, red night mode, autoguider, variable GoTo speed, and LED brightness. You can also set the time of reversal of the objective tube (Meridian Flip) according to your preference. Even if the object moves south during tracking, you can prevent the telescope tube from reversing. Important Information Not usable on old SX mounts with the old blue Star Book Technical Information about the Wifi Module CPU with 32-bit CISC processor at 120 MHz The unit connects to the mount via a D-SUB 9PIN connector, as with the STAR BOOK TEN. It has a 6-pin, 6-wire modular connector for external autoguider operation.

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.
