Orion UK Carbon Fibre Tube Newtonian CT8 - 200/900 mm f/4.5

Orion UK Carbon Fibre Tube Newtonian CT8 - 200/900 mm f4.5

The CT8 is the introductory model in Orion Optics´ CT range of telescopes. Not only will it enable you to see things thought impossible with a 200 mm telescope but, we know you will find in using it that images overall, even the ones you are perhaps familiar with in the night sky, become so much more detailed and interesting.

Having a 1/10PV primary mirror which, along with the secondary are both Hilux coated, fine detail on the planets becomes a far easier target, contrast is enhanced because of the super smooth reflecting surface which collects all the light into a highly detailed image plane, perfect territory for high magnification viewing.

The CT Ultra Newtonians

The CT Range has a sandwich construction carbon fibre tube with a very pleasing gloss external surface and matt black internal tube surface. Offering the ultimate physical stability with virtually zero expansion for focal plane maintenance.

The rear mirror support is Orion Optics´ 9 point flotation CNC machined mirror cell. This maintains positional accuracy and hence perfect image quality. Also at the rear, their fan cooling system will minimise cool down times and help maintain image quality during viewing. Fan(s) can be left in continuous operation.

Fitted with a precision 2″ focuser with silky smooth reduction gearing.

Both sides of the tube rings are flat with internal M6 threats. So you can attach numerous accessories such as dovetail plates and guiding scopes.

A quality adjustable 50 mm achromatic finder is included to assist finding the faintest of objects. No eyepieces are supplied with CT OTAs. Also available as an optional extra is a choice of dovetails.

In terms of optical performance, the CT range are unsurpassed. Each model is supplied with a Zygo report showing all the relevant details of the mirror’s performance in Orion Optics´ optical laboratory. With any CT telescope you are guaranteed the best optical quality available in a precision Newtonian. You will experience the sky in a different perspective after seeing exactly what the highest quality of optics can deliver in image quality.
