TS-Optics hyperboloid Astrograph with 200 mm Aperture and f/3.2:
These astrograph Telescopes have been perfectly designed to the high demands of modern astrophotography.

Due to the extremely fast focal ratio of f/3.2, you can take very detailed shots of deep-sky objects in just one night, using high magnification at the same time thanks to the large 8" aperture.

Unlike standard Newtonians with a parabolic mirror and a Coma Corrector, these Hypergraphs have a hyperbolic primary mirror and an specially designed corrector built into the focuser.

The advantages and features of the TS Hypergraphs at a glance:

• Specially designed optics which are optimised for astrophotography, with excellent high resolution over the entire useable image field.
• Carbon tube for a significantly better focus stability than with a metal tube. Refocusing after temperature changes no longer required and the images appear much sharper.
• Despite the extremely fast focal ratio the telescope is easy to collimate and it keeps collimation well even during transport.
• Uses built in micro-focusing which is necessary at a focal ratio of this speed.
• High-quality CNC tube rings and a GP/Q5 dovetail bar are included
• Carry handle with support for a finder shoe.
• Easy camera connection via the M48 x 0.75 connection thread on the focuser. The working distance is 55 mm.

Easy camera connection via the thread of the focuser:
When dealing with such high resolution and fast optics, a threaded connection on the camera is necessary to prevent tilting and unsharp stars.

The 3" R&P focuser has a female M63 x 0.75 thread and a male M48 x 0.75 thread. The working distance from this thread is perfectly ranged at 55 mm. This matches the distance which a DSLR camera and the matching T-adapter will need. Even modern astro cameras, such as Explore Scientific & ZWO, are already supplied with an M48 adapter kit which matches this distance.

Individual Testing of each Hypergraph Telescope:
The hypergraphs must undergo a complete optimization and check at Teleskop-Service Germany before delivery. These steps include:

1. Removal of the main mirror cell and tightening of all screws, as they are usually loose.
2. Optimizing the fit of the main mirror in the cell - not too tight and not too loose.
3. Cleaning the main mirror and the inside of the tube.
4. Checking and optimization of the focuser
5. Collimation of the whole system and check of the collimation stability
6. Quality control checks on the manufacture of the telescope.
