More about the series VX...

The VX series of telescopes encompasses some of the major benefits of the high quality CT series while being much more affordable. The offered VX instruments come with the same high quality optics as the CT series and are supplied with a Zygo interferometer report.

All models are fitted with a straight 50mm finder and a quality 2" focuser (including a 1,25" adapter). An aluminium tube allows the VX telescopes to be fitted to mounts easily because of its low weight. Precision, fan cooled, 9 point suspension mirror cell gives perfect support and cooling to the main mirror allowing the accuracy of the mirror to be maintained when cooling and controlling the weight distribution with the nylon support points.

A VX telescope will give some of the best images possible in a serious introductory telescope.

Mirror Cells: The best optics in the world can be literally ruined unless they are supported correctly in a telescope’s body. Badly designed mirror supports (cells) are more than capable of turning the image from a 1/10PV wavefront mirror into worse than a whole wavelength of inaccuracy. This telescopes comes with a computer optimised, anodised aluminium surface cell with built in cooling fan (12V DC).
It has a 9 point, nylon66 tipped suspension system which spreads the ‘load’ of the mirror as evenly as possible over those 9 points at the back of the mirror.

Focuser ACU-2S: This is a high quality 2” (50.8mm) Crayford focuser. The actual mechanism is ultra smooth, both in its normal focusing speed and, in its lower geared 10:1 ratio micro adjustment for precise focusing with an eyepiece or camera. For photography it is ideal for small to medium sized cameras, including DSLR and medium format CCD chips. Looking the knurled knob will tighten the draw tube in the chosen position and no movement is produced to offer, sharp, flawless images.
