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 our 9 Point Flotation CNC machined Mirror Cell. This maintains positional accuracy and hence perfect image quality. Also at the rear, our 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.

A Quality adjustable 50mm achromatic Finder is included to assist finding the faintest of objects. No eyepieces are supplied with CT OTA's. Also available as an optional extra are Baseplate Attachments and 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 our 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 optica can deliver in image quality.

All our CT range primary mirrors are made from Schott Borosilicate Low Expansion Suprax glass (virtually identical to Pyrex), as are all our primary mirrors on all ranges of telescopes. The mirrors are all produced to exacting paraboloidal standard configuration to Ultra accuracies. How exact are they? Well, we don’t release one to our coating department unless it achieves a surface accuracy of 1/20 wave (1/10PV wavefront) or better. How do we know when we have achieved that very high degree of accuracy?

We use one of the worlds most exacting measuring devices, a Zygo Laser Interferometer. Take a few minutes and visit the Zygo page and be amazed at just how good this machine is at measuring optics, it can measure optical distances which are smaller than 2,000, yes, 2,000 times smaller than the thickness of a human hair.

Without a Zygo or similarly accurate and reliable measuring instrument, it is impossible to give accurate measurements of an optics’ or telescope’s performance. Only the best manufacturers in the business of making telescopes use them because they are not suitable for mass produced telescopes, they are slow to use and need highly skilled technicians to operate them, it just does not lend itself to anything other than the highest quality, hand figured optics, definitely not mass produced optics to a tight budget.

Primary mirrors are Hilux coated for the highest possible aluminium protected reflective surfaces available.


Moving into the region of large aperture telescopes we offer our CT14, a 350mm Newtonian of remarkable pedigree.
Still capable of transportation relatively simply in a family car, take one of these out to a dark site and hold onto something firm, you are in for a shock.

Over 3 times the light grasp of a 200mm scope ensures faint detail is given sufficient attention to be readily visible in all subjects. With also 75% more detail available in images compared to a 200mm telescope, detail and faint objects otherwise normally overlooked or not even hinted at in images is clearly visible and allows a more realistic picture of your subject to be seen. When applying these featured specifications to perhaps Jupiter, even the red spot begins to take on detail and yields the turbulence around it.

Being relatively fast, f4.7, you will be greeted with deep sky images with an enormous amount of inbuilt detail, even faint wispy detail seen in other telescopes takes on a more defined, crisper appearance.
