TS 2'' GPU COMA CORRECTOR NEWTONIAN

TS-Optics NEWTON Coma Corrector 1.0x TSGPU Superflat - 4-element - 2" connection

The TS GPU Aplanatic Newtonian Coma Corrector for Astrophotography

The coma corrector 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. Just enter TS Superflat Coma Corrector on Astrobin and you will see how well the corrector works on Newtonian telescopes.

In opposite to 2-element correctors, the stars are not enlarged, there are no halos. Furthermore, the whole construction is designed to be free from reflexes. Even bright stars wll 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
• No change of the focal length.
• The focus plane is shifted outwards by 20 mm. 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 screwed to the focuser by an optional adapter.
• The TS GPU corrector offers correction up to full-frame sensors. For perfect illumination, a FLAT is necessesary.
  
  

The optimal working distance from the M48 thread to the camera sensor:

The optimum working distance is 55 mm from the M48 male thread. The external thread itself does not count, as it disappears in the connection adapter. With our extensive range of adapters, you can always achieve the optimum distance.

Die Innovation from TS Optics - screw the GPU corrector to the focuser.

With optional adapters you can screw the corrector to the drawer. For this purpose the corrector has an extended M48x0.75 thread on the camera side. Simply turn down the lock ring and you have 3 mm more M48 thread for screw adaptations available.

By the threaded connection, you gain stability and also accuracy. The image is improved and heavy cameras can be used, too.

Suggestion for an astro camera with 17.5 mm camera back focus and T2 connector:

The camera back focus or flange focal distance is the distance from the T2 (M42x0.75) thread to the sensor. Most cooled astro cameras have this distance.

Adaption with filter drawer for filter change:

• Astro Camera ... 17.5 mm flange focal distance
• TSM48-T2L extension to M48 ... 6 mm travel
• TSFSLM48 ... Filter drawer ... 18 mm travel
• BAHYP14 ... 14 mm M48 extension ... 14 mm path
  
  

The additional 0.5 mm compensates the optical path of the filter. About 1/3 of the filter diameter must always be added to the working distance of the corrector (55 mm).
