Vixen extender PH set for R200ss

The Vixen corrector PH is a 3-element Wynne corrector for demanding applications. Designed for the Vixen R200SS Newtonian reflector, but also suitable for other optics with similar specifications.The optical design consists of 3 lenses in 3 groups. The corrector provides excellent correction of system-induced coma of parabolic mirrors and the resulting spherical aberration. The corrected field has a diameter of 44 mm, making it suitable for the 24x36 mm format (full-frame DSLR/CCD cameras). This guarantees razor-shape images across the entire field. The lens surfaces are coated with a cutting-edge 99.9% anti-reflective AS coating, which is also used for Vixen's flagship VSD100F3.8.Turn your Vixen R200SS reflector telescope into the perfect astrograph!FEATURESPremium coma corrector for the R 200SS Newton refelctor 3 lens systems in 3 groups, guarantees absolute colour purity and sharp stars to the edge of the field of viewImage illumination up to 44 mm for full-frame imagesReduces the focal length of the R 200SS from 800 mm to 760 mm 1:3.8Also suitable for visual observations with an eyepiece adapterWeight: 175 gDELIVERY CONTENTComa correctorDust caps on front and back

SXD2 mount with SD103S telescope These telescope sets are ideal for beginner observers. The sets include a telescope, a mount with automatic tracking, a tripod and eyepieces. Featuring the STARBOOK TEN control system, the telescope locates celestial objects automatically so that you don't need to search for them manually. Even if you're not an expert, you can still give your friends an exciting tour through the night sky! The SXD2 mount comes with the new STARBOOK TEN controller and the PFL polar viewfinder, which allows you to configure the mount quickly and easily via reference stars. The SXD 2 mount in detail With a combination of the best features from the Sphinx series and the all-new STAR BOOK TEN manual controller, Vixen has developed a new generation of SX mounts for demanding observers and astrophotographers. The SXD2 mount comes with the new STAR BOOK TEN controller and can be operated manually or with a computer. Featuring the same precision stepper motors as the top-of-the range AXD mount, the SXD2 sets a new standard for performance in the Vixen mount range. Compared with the SX mounts, the SXD2 has a quieter tracking system, and the increased precision of the motors provides better performance for the long exposure times used in astrophotography. Precision stepper motors and micro-step motion control system The star feature of the SXD2 is the precision stepper motors, which offer better performance and responsiveness than previous models. The micro-step motion control system has powerful yet very quiet drive characteristics that offer both fine control and quick swivel movements. Built-in bearings The bearings of the RA and DEC axles and the worm shafts were significantly improved in order to reduce the load on the motors. The motors are much quieter than those on previous models. Robust RA and DEC axles High-precision and thick steel shafts in RA and DEC axles increase the robustness and stability of the SXD2 mount. High-precision worm gears High-precision processing technologies were used to rectify problems with the worm gear. The edges of both worms and worm gears are particularly smooth, which enables them to deliver very high precision. Declination axis functions as counterweight The sturdy motor units are located in the lower section of the declination axis to ensure that the SDX2's centre of gravity is below the intersection of the RA and DEC axis. As a result, fewer additional counterweights are required. The SD103S in detail 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 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.
