A new take on a classic design, superior to the usual red dot finder - which will fit many telescopes and larger binoculars.Explore Scientific ReflexSight™ LED projection viewfinder, uses proven functionality with versatility, while having enhanced performance features.Looking through this viewfinder shows multiple deep red target circles projected against the night sky.  Both eyes can be used for quick and easy star hopping, in order to target objects in your telescope. The big advantage is that you can see the entire night sky without magnification and not just a small section of the sky, as you would through a magnified finderscope.  This makes Goto aligning quick and easy and speeds up acquisition of targets.New "Multi-Dot" target circle pattern (in standard circle diameters of 4.0 degrees, 2.0 degrees and 0.5 degrees), prevents blocking of stars within the field of view.  Using the widths of the projected circles as reference points allows those users with non-goto telescopes to easily work out the location of non-visible targets, with reference to more easily visible stars.  The projection screen size is a generous 55 x 35 mm.Multiple mounting options. The Explore Scientific ReflexSight™ LED projection viewfinder's base fits standard "Vixen-style dovetail" finder bases, allowing the user to attach this finder to a wife array of commercially-available telescopes, without modifying the telescope itself. A ¼ inch x 20G threaded adapter (photo tripod thread) is built into the finder base, allowing the finder to be attached to a variety of telescopes, via piggyback camera adapters with a photo tripod threaded hole.Functional design and intuitive use: the smooth housing, with no sharp corners, prevents snagging. Easily accessible battery compartment, taking 2x standard AAA alkaline batteries (not included), which power the frugal LED illuminator. The low power consumption of the LED lighting ensures a long operating time. Large, continuously adjustable brightness control with knurled knob head can be easily operated with gloves. Click the rotary switch to turn off completely. Rear-facing, tool-free three-point parallax knurled collimation knobs, again, easy to operate even with gloved hands, ensure you are well locked-on to the main optical axis of your telescope. The projection screen is coated, to minimise annoying reflections and allow you to concentrate on the finder's target and the night sky behind it.  Comes complete with screen and optics cover. The extremely compact design allows mounting even on small, lightweight telescopes - truly a finder for all!FEATURESReflexSight LED projection finder with deep red target circles Standard circle diameters 4.0 degrees, 2.0 degrees and 0.5 degreesProjection screen size: 55 x 35 mmFits standard Vixen-style dovetail finder shoes There is also a ¼ inch x 20G female photo tripod thread in the base Can be mounted via piggyback camera adapters etc. Operates on standard AAA batteries (not included) Smooth housing with no sharp corners, prevents snagging Comes complete with optics and screen cover Compact design and easily accessible battery compartment Large, continuously adjustable brightness control with knurled knob Click switch to turn off completely Tool-free three-point collimation parallax adjustment with easily accessible knurled knobs Can also be mounted on small and light telescopes WHAT'S INCLUDEDReflexSight LED projection finder 

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.
