A new apochromatic refractor with high performance Super-ED glass (= SD). The FPL53 glass reproduces an extremely clear and sharp image by an exceptionally high degree of elimination of residual chromatic aberrations. The advantage of these SD refractors is their short length and low weight. The SD glass is designed to bring all beams of violet, red, blue, yellow and green very precisely together on the same plane. The special lens material, reduces chromatic aberration across all colors. In combination with the new optional SD Reducer HD Kit or SD Flattener HD, these refractors allow illumination with a 44mm image circle for full format SLR cameras. FEATURES Lens diameter: 103mm Type of coating: Multi-coated Focal length: 795 mm (f7.7) Resolution: 1.13 arc seconds Visual limit value: 11.8 mag Max. magnification: 206x Tube length: 810mm Tube diameter: 115mm Tube weight: 5,4kg Viewfinder telescope: 7x50 with illumination unit Adapter 7.0 degrees FOV included Connections/adapters: thread 60mm and 31.7mm for T-ring Eyepiece adapter: 50.8mm (2 inches) and 31.7mm (1.25 inches)Backfocus without Reducer: 150,4 mmBackfocus with Reducer: 63,5 mmFlip mirror included SCOPE OF DELIVERY Optical Tube Tube rings with carrying handle GP dovetail adapter Flip mirror Dust covers

A new apochromatic refractor with high-performance Super ED glass (=SD). The FPL53 glass reproduces an extremely clear and sharp image by eliminating residual chromatic aberration. Another advantage of these SD refractors is their short length and lightweight design. The SD glass is designed to focus all beams of violet, red, blue, yellow and green light exactly onto the same level. The special lens material reduces chromatic aberration across all colours. Together with the new optional SD Reducer HD Kit or SD Flattener HD, these refractors provide illumination with a 44 mm image circle for full-frame SLR cameras.The ED81SII, ED103S and ED115S refractors were originally designed for visual observers or photographers with an APS-C camera. However, the new SD series features new inner panels which are optimised for full-frame cameras.The large focuser allows you to attach heavy cameras without the telescope tilting.The telescope also comes with a folding mirror for making observations in unfavourable conditions,as well as a T2 thread for connecting a DSLR camera.FEATURESObjective lenses:  115 mm 2-lens apochromatFocal length:  890 mm (f7.7)Resolution and limiting magnitude:  1.01 arc seconds; 12.1Light-gathering power:  270x Backfocus wihout Reducer: 147,2 mmBackfocus with Reducer: 63,5 mm Dimensions and weight:  125 x 930 mm, 6.2 kgAdapter and connections:  50 mm sleeve DELIVERY CONTENTED 115 telescope/lens barrelCarry handleFolding mirror7x50 viewfinderTube clampsDovetail adapter

The AX103S is a top-of-the-range ED apochromat in the refractor series. It features a triplet ED object lens and a rear-mounted field-flattener lens. The f8.0 refractor contains a central ED lens in the objective and reduces chromatic aberration to an absolute minimum. An optional focal reducer can reduce the aperture ratio to 1:5.6 in order to provide quicker results for astrophotographers. The built-in field flattener lens provides a sharp image across the entire field of view – an essential requirement in astrophotography. The 60 mm ring on the focuser allows you to attach a 2’’ eyepiece or accessories and a camera adapter. The AX103S is specially designed for photography, but also offers stunning visual performance, especially for observing the moon and the planets. The AX 103S is corrected for full frame photography and provides razor-sharp pictures right into the corners of the image field. This telescope is guaranteed to provide a lifetime of outstanding performance!

Astrophotographers generally use two different focal lengths: Short focal lengths for overview photos and extensive deep-sky objects, and long focal lengths for objects which are further away. Our aspherical mirror optics offer the perfect solution for these scenarios. The VISAC primary mirror (Vixen Sixth-Order Aspheric Cassegrain) is specially designed for astrophotography and provides a fully flat and true-colour image over the entire image frame. Thanks to the three-element field corrector in front of the convex secondary mirror, there is no spherical aberration, coma or field curvature. Although the device is designed for astrophotography, it is also suitable for visual observations.

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
