Product description

SD81S, SD103S and SD115S, these are the new apochromatic refractors from Vixen with super-ED (= SD) glass!

The redesigned lens enlement with FPL-53 glass reduces colour error (chromatic aberration) to a hardly noticeable degree, and ensures an extremely clear and sharp image. In combination with the new optional SD Reducer HD or SD Flattener HD kits, these refractors illuminate and obtain a 44mm image circle for full-frame DSLR cameras. The interior baffles have been optimised for the M8.

The SD apos from Vixen are ideal for astrophotography. Anyone who has ever looked through a Vixen apo will never want to use another telescope, also for visual observation. The practical flip mirror enables the simultaneous connection of an eyepiece at a comfortable viewing angle and a camera.

Another advantage of Vixen’s SD refractors lies in their relatively short length and low weight.

The Sphinx Professional 2 (SXP2) mount is a further development of the classical SXP with improved load-bearing capacity and accuracy of movement - the latter is achieved thanks to a toothed belt drive and large taper roller bearings. This Sphinx purrs like a kitten!

Also the mount chassis has a higher material strength in comparison to the previous SX models. The central axis of the telescope is secured in a fork in order to ensure a high level of stability of the pole block. It is the same fork as seen in the heavier AXJ. With this a fast, but also very stable setting of the latitude is possible.

To set up the mount a 6x20 polar finder is pre-installed. With this, you can set up the polar alignment in both the northern and the southern hemispheres. This polar finder has a variable illuminated reticle with automatic shut-off function. The brightness has 8 levels of adjustment. The Polar finder has a direct set-up using three reference stars and can reach an accuracy of up to 3 arc minutes. If you want to set up the mount quickly and do not need the accuracy required for astrophotography, you can also use the optional compass QPL.

The mount head has a diameter of 35 mm and has eight threaded holes for M8 screws, which are arranged at intervals of 45 degrees. The threaded holes can also be used to attach rails from manufacturers other than Vixen.

The counterweight bar has the same standard diameter as all Sphinx mounts, and so the same counterweights can be used. The bar need not be unscrewed for transporting, but simply slides into the housing. Since the design of the Sphinx mount uses the motor used as a counterweight, the mount requires relatively little additional counterweights.

The Star Book Ten controller is available for purchase as a standalone item only to upgrade the SX2 mount. It is included as standard with the SXD2, SXP and AXD mounts and is not backwards compatible with the Star Book controller supplied with Vixen’s previous generation SX and Atlux mounts.

SX-HAL130 aluminium tripod: Strong aluminium section legs and a large receiving area for SX and SXD mounts ensure very high torsional rigidity. This result can be seen immediately when the tripod is used for astrophotography - vibration becomes a thing of the past. For the taller among us, the height adjustability of 81 to 130cm really comes into its own. With a weight of only 5.5 kg, it is wonderful for use on excursions.
