GSO-Optics 8" F5 Newtonian reflector telescope for observation and astrophotography - optical tube assembly
  • Aperture 200 mm (8") / focal length 1000 mm / photographic speed f/5
  • High quality parabolic primary mirror with 94% enhanced reflectivity coatings for a brighter and contrastier image
  • Largely dimensioned secondary mirror with 63 mm diameter (minor axis) - very good illuminated field for astrophotography
  • Primary mirror cell and secondary mirror holder completely made of metal - not plastic - fully adjustable (image of the secondary mirror holder at left)
  • Precise 2" Crayford focuser with 1:10 dual speed transmission for exact focusing - already included
  • Primary mirror cooling fan for less cooling time
  • Rigid steel tube instead of a wobbly aluminium tube - better adjustment stability
 
GSO 8" f/5 Newtonian telescope - for observing and astrophotography
This telescope is a true all-rounder and ranks among the best in this range range. Through the versatile focal ratio of f/5, the Newtonian offers best prerequisites for lunar and planetary observations. The optimized secondary mirror is designed for deep-sky observations as well as for astrophotography.
 
The advantages of the GSO Newtonian at a glance
  • Moderate focal ratio for short exposure times for astrophotography.
  • Very high sharpness on moon and planets
  • Secondary mirror provides good illumination, for example for DSLR cameras
  • Large backfocus allows using popular coma correctors and cameras
  • High-quality primary mirror of optical BK7 glass with enhanced 94% reflectivity
    coating provides a bright, clear image.
  • Stable 2" Crayford focuser with 10:1 dual speed and 1.25" reduction adapter
  • Quicker cooling down, quicker observing, quicker photographing through fan for the primary mirror
  • Steel tube and metal mirror cells for optimal adjustment stability
  • Since many years, we are a GSO distributor and we know about the exceptional quality of GSO telescopes. The manufacturer keeps the optical performance of the mirrors on constantly high level. Significant differences do not occour at GSO, in opposite to other suppliers from far east.
 
What's in the Telescope Box
  • 200mm f/5 Newtonian optical tube assembly
  • 2" dual speed Crayford-style micro focuser with 1.25" eyepiece adapter
  • 8x50mm straight-through finder with bracket and base
  • Tube rings
  • 13" red Vixen-style dovetail rail
  • 2" extension tube with 35mm extension
  • Front dust cover
  • No instruction manual is included
 
The precise 2" crayford focuser with 1:10 micro transmission
We offer this Newtonian telescope with a 2" Crayford style focuser with integrated 1:10 dual speed transmission. This focuser works very precise even with heavy accessories like astro cameras. With a bit of experience, you can achieve accuracies around 0.08 mm which is sufficient even for very high resolution sensors.
 
High-quality primary mirror with f/5 and 94% reflectivity

This Newtonian shows its full potential at observation and astrophotography due to a high-quality primary mirror made of optical BK7 glass, free from internal stress. The parabolic mirror has a 94% reflectivity coating, thus offering a brighter and contrastier image. You can instantaneously notice the difference to a standard coating.

Due to the focal ratio of f/5, this Newtonian belongs to the all-round telescopes for astrophotography and observing.

No vignetting at the edge - full illumination through large 63 mm secondary mirror No shadow at the edge, you will be satisfied with a bright image with full illumination even with modern DSLR or CCD cameras. But 2" wide field eypeces are also supplied with light up to the edge of the field stop.

Enjoy your image more with optimal field correction - Only a good coma corrector turns this Newtonian into a true astrograph. Makes a true astrograph out of this Newtonian.

 
EQ-5 Mount with Dual Axis Motor with Hand Pad controller / Polar scope
  • Installing a motor drive on your equatorial (EQ) mount makes tracking objects hands-free and easy
  • Motor(s) slowly rotate your EQ-mounted telescope so it follows celestial targets as they appear to migrate across the night sky
  • Each motor drive provides regulated sidereal-rate tracking in Right Ascension (R.A.) as well as alternative speeds
  • Makes observing objects in the night sky easier and more enjoyable
  • STARTRACK EQ-5 Dual-Axis electronic drive provides motorized dual-axis control for high-power viewing and astrophotography
  • Drive controller allows sidereal tracking and electronic control of declination
  • Features 2x, 4x, and 8x speeds and pause mode
  • Includes two motors, controller and battery pack
  • Requires 4 D-cell batteries for operation (not included)
