TS 10" f/3.4 Hypergraph - Parabolic Newtonian Astrograph

The compact Newtonian astrograph has been developed from the proven ONTC series and offers a large corrected field with high speed at the same time. The astrograph is suitable for modern sensors up to full frame format with high resolution at the same time.

Features of the TS 254 mm Hypergraph:

Parabolic primary mirror with primary focal ratio f/4

3" corrector and 0.85x reducer screwed into focuser

100 mm diameter secondary mirror for good illumination up to full frame format

Large 3" dual-speed RAP focuser

55 mm working distance from the M48x0.75 thread

Screw-in option for mounted 2" filters

Additional M54x0.75 and M68 threads for individual adaptations

Tilting option on the focuser

Carbon tube and CNC rings

The distance between the primary mirror and the secondary mirror can be changed, so other correctors can be used.

This is how we hand over every TS Hypergraph to the amateur astronomer

Every TS Hypergraph is assembled for you in our technical department.

Only first-class optical and mechanical components are used.

Each telescope is mechanically optimized and collimated after assembly.

Afterwards, each Hypergraph is tested on our optical bench in autocollimation. The focus is on the interaction of primary mirror, secondary mirror and corrector.

Ech Hypergraph254 comes with a complete manufacturing protocol including star test.

After that, the telescope is prepared for shipment.
