Product information

Altair 8" f/5 Newtonian telescope - for Observing and Astrophotography:
This telescope is a true all-rounder and ranks among the best in this range. Through the versatile focal ratio of f/5, the Newtonian offers best prerequisites for lunar and planetary observations. The optimised secondary mirror is designed for deep-sky observations as well as for astrophotography.

Only a good coma corrector turns this Newtonian into a true astrograph. Our recommendation is the Maxfield Newtonian Coma Corrector 0.95x Product code: T-969KNDWAWD-67 which is perfect for this telescope, offering very good edge sharpness. The working distance from the M48 thread is 55 mm. With a T-ring, you are automatically at the right distance for astrophotography with DSLR cameras. For Hypercam or other dedicated astro cameras, you can work out the spacing using this guide here with the coma corrector substituted for reducer/flattener.

Features at a glance:

  • Moderate F5 focal ratio for astrophotography and visual observation.
  • Very good for high power imaging of the moon and planets with GPCAM.
  • Secondary mirror provides even illumination on DSLR or Hypercam dedicated astro cameras.
  • Generous back focus 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.
