Orion Optics UK Telescope N 200/900 VX8 OTA

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.

The Optics N 200 (8″): The brightness of an object in a telescope depends on the size of the main mirror i.e. how much light it collects and sends to your eye, or camera. This is calculated based on the area of the mirror. In the case of the 8″-telescopes, they both have over 40% brighter images than the 6″ (150mm) models. To add to that, the detail in a telescope’s image is controlled by the diameter, or aperture of the mirror. The 8″ have mirrors 33% larger than the 6″. These two features give you not only a much brighter image but also, a much more detailed image allowing you to use higher magnifications on the telescope.

Standard or Long? The telescopes in this series have a short focal length which, with the addition of a camera adaptor and camera, can give you some spectacular photographic performance, primarily on Deep Sky objects. The L-Version has a higher focal length. It can provide you with stunning visual images at higher magnifications and be extremely useful in photographing the planets and the Moon.

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.

It is not only important which telescope you buy, but also where you buy it.
