Will the Celestron C14 optical tube fit on the Vixen-class dovetail head (CG-5 / EQ5 class)?

Whether the Vixen-class dovetail head (CG-5 / EQ5 class) can carry the Celestron C14 optical tube tube steadily, from the published tube weight and mount payload.

Optical tube weight
45 lb

22 lb (the EQ5 / CG-5 class German equatorial, a common home for a 150 mm to 203 mm SCT tube)
Tube as share of payload

Over payload. The Celestron C14 optical tube tube weighs 45 lb, more than the Vixen-class dovetail head (CG-5 / EQ5 class) rated payload of 22 lb, so the mount is overloaded and views will shake. Choose a heavier mount.


A mount's rated payload is for the whole instrument, not just the bare tube. The Celestron C14 optical tube tube is 45 lb, which is 205% of the Vixen-class dovetail head (CG-5 / EQ5 class) 22 lb rating before you add a star diagonal, finder and eyepiece.

For steady high-magnification views many observers keep the real load below about 70% of the rated payload, because damping time grows quickly as a mount nears its limit. The eq5 / cg-5 class german equatorial, a common home for a 150 mm to 203 mm sct tube.
