GSO 150mm f/5 Newtonian with coma corrector - Astrophotography EditionAstrophotography 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 fulfills the requirements and guarantees pleasure with astrophotography - right from the beginning.
The advantages of the Newtonian at a glance- 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 63 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 Baader MPCC Coma Corrector is the best corrector of its class. It guarantees a very good correction up into the corners of the field even with larger camera sensors.
The high-quality 2" Crayford focuserThe 2" Crayford focuser with 1:10 speed reduction is included. Accessories are evenly clamped with a brass compression ring. The 1.25" reducer is equipped with a brass ring, too. The focuser will not tilt 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.
The TS Komakorr Maxfield Newton coma corrector from Baader
Every Newtonian telescope has coma towards the edge, the stars are rendered distorted. The coma corrector eliminates this coma and the stars become point-like. The Maxfield also improves the focal ratio from f/5 to f/4.75, making exposure times even shorter.
- 3-Elemet design for sharper stars than 2-element correctors.
- highest sharpness performance over the entire image field
- M48 connection thread on camera side
- easy adaptation of cameras by T-ring
- working distance from M48 thread 55 mm (DSLR camera and T-ring)
