The Quattro 200P is a fast parabolic imaging Newtonian with a nominal 200 mm aperture and 800 mm native focal length at f/4. Its low-expansion borosilicate primary is intended to reduce sensitivity to changing temperature during an imaging session.
Optical correction
Use a matching f/4 coma corrector to improve off-axis star shapes when imaging. Corrector spacing and camera adapters must follow the specification of the chosen corrector. A reduced focal ratio is not assigned to the native optical tube.
Focusing and structure
A 2-inch dual-speed linear-power focuser supports precise camera focus. Thin 0.5 mm secondary vanes and ray-traced internal baffles reduce diffraction/stray-light effects. The listed finder is 8×50.
Mounting and model details
The manufacturer’s published tube mass is 9.5 kg. The global table identifies the physical optical diameter as 205 mm; the nominal product designation is retained.
