Skywatcher 2" Coma Corrector for Newtonian Telescopes - perfectly suitable for DSLR cameras

The Skywatcher coma corrector is optimized for all Newtonian telescope with a focal ratio of f/6 to f/4.5 and a 2" focuser. The corrector is suitable for photography and observing. It corrects the Newtonian coma and provides pinpoint stars to the edge.

The advantages of the Skywatcher coma correctors:

Versatile - usable for photography and for observing

Better illumination due to the M48 thread - illuminates even large sensor diameters

M48 adapters for DSLR available

Very good multi-coated optics for maximum sharpness without annoying reflections

Reduces the focal length by the factor 0.95. The focal plane is moved by 3 mm towards the tube then.

The corrector fits to any Newtonian with 2" focuser and a working distance of at least 60 mm. These prerequisites are fulfilled by almost all Newtonian telescopes on the market.

With the 2" adapter, you can also use eyepieces with the corrector and benefit from the better quality in the field.

Question:
How do you have to measure the working distance?

Answer from Teleskop-Service:
The working distance is measured from the beginning of the connection thread on the housing of the corrector (see example picture):
