GSO 150mm f/5 Newtonian - Astrophotography Edition
Buy a Coma Corrector separately- Highly Recommended with this telescope.
Astrophotography with a fast Newtonian telescope is a pleasure. Very good results are possible from the beginning. The precondition is that the components fit together and the optics are as good as the mechanics. This combination fullfills the requirements and guarantees pleasure with astrophotography - right from the beginning.

  • Quality optics from GSO with outstanding image quality
  • No focusing problems even with digital SLRs
  • Very good 2" Crayford focuser with 1:10 speed reduction
  • Solid steel tube guarantees very high adjustment stability and stiffness
  • Primary and secondary mirror are completely adjustable
  • The secondary with 55 mm is largely dimensioned for a very good illumination over the complete field
  • 94% forced coating for a brighter image and shorter exposure times
 
The high-quality 2" Crayford focuser
The 2" Crayford focuser with 1:10 speed reduction is included. Accessories are evenly clamped with a brass compresssion ring. The 1.25" reducer is equipped with a brass ring, too. The focuser will not wobble even when used with heavy cameras. With the 1:10 speed reduction, precise focusing is possible. Point-shaped stars over the whole field are the result.
