6" f/4 Imaging Newtonian Reflector Telescope with 2" Monorail Focuser

TSIMN6

  • $990.00

  • Designed for astrophotography and rich-field observing
  • Improved optical and mechanical system
  • Fast astrograph with excellent field illumination
  • Compact, travel-friendly design

The 6” Imaging Newtonian delivers optical performance and features typically found only in larger systems. This fast Newtonian telescope is optimized for rich-field observation and astrophotography, offering excellent field illumination, high brightness, and sharp image definition. Its diffraction-limited optical system provides impressive image quality that will satisfy even demanding observers and astrophotographers.

TS 6" f/4 Imaging Newtonian – Key Advantages

  • Fast, diffraction-limited optical system (f/4) for wide-field observing and astrophotography.

  • Bright, high-contrast images thanks to enhanced mirror coatings with up to 94% reflectivity.

  • Excellent field illumination provided by the large 63 mm secondary mirror.

  • Robust mechanical construction designed to resist flexure and maintain collimation, even with heavy imaging equipment attached.

  • Upgraded Monorail focuser with 1:10 dual-speed fine focusing, offering greater stability and load capacity compared to traditional Crayford designs.

  • Ideal for travel and remote observing, with a compact tube length of just 58 cm and a weight of only 5.3 kg (including tube rings, excluding finder scope).

 

Excellent Field Illumination

The telescope's tube features a generous 173 mm inner diameter,  minimizing off-axis vignetting and allowing the optical system to fully illuminate the field. The 63 mm secondary mirror provides ample illumination for both 2" eyepieces and cameras equipped with larger sensors.

The system also offers sufficient back focus for a wide range of accessories, including the use of binoviewers with moderate glass-path compensation. This versatility makes the telescope well suited for both visual observing and astrophotography applications.

 

Astrophotography with the TS 6" f/4 Imaging Newtonian

This compact telescope is designed specifically for serious astrophotography without compromise. Its rigid tube construction and robust Monorail focuser provide excellent stability, allowing it to support heavy CCD and DSLR cameras with confidence.

The large 63mm secondary mirror delivers excellent field illumination and reduces vignetting compared to many similar systems, helping to achieve more evenly illuminated images across the sensor. Combined with its fast f/4 optical system, the telescope is well suited for capturing wide-field deep-sky objects with shorter exposure times.

 

Precision Monorail Focuser

The Monorail focuser is an advanced evolution of the traditional Crayford design. Instead of relying on small ball bearings to support the load, it uses a solid stainless-steel guide rail, providing superior rigidity and stability when carrying heavy accessories and imaging equipment.



·  Exceptional stability with virtually no image shift caused by focuser tilt or flexure.

·  Adjustable tension control via a large knurled friction adjustment knob.

·  Secure focuser lock with a robust knurled locking screw to maintain precise focus during imaging sessions.

·  Brass compression rings securely hold accessories in place without marking or damaging barrels.

·  Precision 1:10 dual-speed focusing for smooth, accurate focus adjustments, critical for astrophotography and high-magnification observing.
