Coma corrector optimised for fast f/5 Sky-Watcher Newtonian and Dobsonian telescopes with a 2-inch focuser. It provides pinpoint stars to the edge of the field without altering magnification and is suitable for both visual use and imaging.
Designed for fast f/5 Sky-Watcher Newtonian and Dobsonian telescopes, this coma corrector is intended for instruments equipped with a 2-inch focuser.
Its optical system corrects the coma characteristic of fast Newtonian telescopes, significantly improving image quality across the field.
Stars therefore remain pinpoint towards the edge of the field, allowing wide-field views to be used more effectively.
The corrector can be used for both visual observation and imaging with a compatible DSLR camera.
Optimised for Sky-Watcher f/5 Newtonians
The corrector is optimised for:
• Sky-Watcher f/5 Newtonian telescopes
• Sky-Watcher f/5 Dobsonian telescopes
• Instruments equipped with a 2-inch focuser
Coma Correction
Coma is primarily visible towards the edge of the field in fast Newtonian telescopes.
This corrector is designed to improve star images towards the field edge and provide better correction across a wider area.
Wide-Field Observation
The corrector provides wide-field views with pinpoint stars extending towards the edge of the field.
This is particularly useful with fast Newtonian telescopes.
Unaltered Magnification
The corrector does not alter magnification.
Magnification therefore remains:
• Unchanged
Visual Use
The necessary adaptors for visual use are supplied with the corrector.
It can therefore be incorporated into a compatible visual setup using a 2-inch focuser.
Imaging Use
The corrector can also be used for imaging with a DSLR camera.
A suitable camera-specific connection is required.
M48x0.75 Connection
For DSLR imaging, a suitable:
• M48x0.75 adaptor
is required.
Sky-Watcher provides corresponding adaptors for:
• Canon
• Nikon
