The GSO 10 "f / 4 Newton will be checked and adjusted by us before delivery The focuser will be discontinued.

All Newtonian telescopes should be adjusted before first use and then periodically for a clear image. We adjust all of our Newton before they leave our house.

These telescopes are shipped free of charge in Germany.

TS 254 / 1016mm Imaging Newton on Skywatcher NEQ6

The 10 "TS Imaging Newton TSIMN10s is optimized for astrophotography and large field observation due to the fast aperture ratio of f / 4. The large sized secondary mirror with 88mm small axis and the ultra-stable 2" MONORAIL excerpt guarantee optimal illumination of the field of vision in photography and also at the observation. When designing the TSIMN10, emphasis was placed on maximum stability and rigidity. The Newton is manufactured by GSO for Telescope Service, taking into account our high quality standards.

The advantages of the TS 10 "Imaging Newton at a glance:

- Fast and diffraction-limited optics with 10 "aperture and f / 4 for short exposure times
- Main mirror made of B270 "optical crown" glass - clearly superior to float glass
- 94% forced mirroring on main and secondary mirrors
- 2 "MONORAIL extract (more stable than Crayford) for heavy and large format CCD cameras
- Built-in cooling of the main mirror for rapid cooling of the telescope
- stable pipe clamps with flat support surface on both sides - hinged
- with only 98cm tube length, the TSIMN is still very compact and portable
- comfortable focus position - also allows the use of DSLR cameras & Off Axis Guider

The Skywatcher mount NEQ6 SynScan GoTo carries the TS Imaging Newton with good stability. We recommend this mount because of its accurate tracking and the sophisticated GoTo control.

Skywatcher EQ6 Goto Mount:

- Mount weight with tripod ... 23.5kg
- Load capacity up to 20kg
- GoTo control with 13,400 stored objects
- PEC to improve tracking
- Autoguiding interface



Good illumination for 2 "eyepieces and astrophotography

The TSIMN10 is optimized for a very good illumination. The diameter of the front panel is generously dimensioned at 29cm so that the tube itself does not fade. Even the 88mm secondary mirror with built-in offset and especially the focuser with 76mm free passage guarantee a picture free of disturbing shading, even when using large format camera sensors.

The 2 "MONORAIL focuser:

TS MONORAIL focuser
The MONORAIL focuser is a further development of the Crayford excerpts. The main advantage is a higher rigidity because instead of small ball bearings that can yield, the storage is done via a sturdy stainless steel rail.

- better stiffness than typical Crayford extracts
- no susceptibility to tilting during clamping
- Adjustment of friction by knurled screw on the base
- Practical clamping with large knurled screw
- Brass ring clamp - 2 "clamping by two screws - no more tilting
- Practical 1:10 reduction for astrophotography
