Περιγραφή
A coma corrector is a corrective lens for Newtonian telescopes. This type of telescope can cause distortion of the image at the edge of the field of view, making stars look like little comets. This aberration is therefore called ‘coma’.
This GPU coma corrector, optical design by Gyulai Pal in Hungary (GPU Optics), is one of the best correctors for astrophotography using high-speed Newtonian telescopes.
- 4-element design for exceptional image quality in the field and along the axes
- Ideally suited to Newtonian telescopes with aperture ratios of f/4 – delivers very good results from f/3.5 to f/6
- High tilting tolerance
- Focal length remains unaltered
- M48 thread camera connection
The corrector can be screwed on to the focuser for improved stability and accuracy.
Optimal distance between M48 thread and camera sensor:
The optimal distance depends on the Newtonian telescope’s focal length
- Focal length up to 600 mm: 53 mm distance
- Focal length from 610 mm: 55 mm distance
The TS Superflat TS GPU coma corrector is one of the best correctors for astrophotography through fast Newtonians.
- 4-element coma corrector for excellent imaging in the field and on the axis.
- Perfectly suitable for Newtonian telescopes with focal ratios of f/4 – provides very good results from f/3.5 to f/6.
- Suitable for full-frame format, depending on the image train and secondary mirror used.
- Very tolerant against tilting.
- Focal length is not changed.
- Camera connection through M48 thread.
- The focus position is moved outwards by 20 mm.
- For better stability and accuracy, the corrector can be screwed to the focuser. Connection adapters for cameras and focusers are available.
