The TS GPU Aplanatic Newtonian Coma Corrector for Astrophotography is a further development of the GPU by Pal Gyulai - GPU-Optics. The result is a high quality 4-element corrector that provides round stars over the entire field of view even with larger camera sensors.
Unlike to 2-element correctors, the stars are not enlarged and there are no halos. Furthermore, the whole construction is designed to be free from reflexes. Even very bright stars will be shown without reflexes or ghostings.
The Advantages of the GPU Coma Corrector:
- Very good coma correction for Newtonian telescopes from f/3.5 to f/6
Suitable for full-frame format, depending on the image train and secondary mirror used.
- No change of the focal length.
- The focus plane is shifted outwards by 20mm. This prevents the corrector from protruding into the inside of the tube.
- Stars are smaller - no halo effects.
- The corrector can be clamped, but also threaded directly to the focuser by an optional adapter.
- The TS GPU corrector offers correction up to full-frame sensors. But for perfect illumination, a FLAT is necessesary.
The optimum working distance is 55mm from the M48 male thread. The external thread itself does not count, as it disappears in the connection adapter. With optional adapters you can even thread the corrector to a filter drawer or similar. To do this, the corrector has an extended M48 x 0.75 thread on the camera side. Simply remove the lock ring and you have 3mm more M48 thread for threaded adaptations.
