Will the Celestron NexStar 5SE fit on the Sky-Watcher AZ-GTi?
Whether the Sky-Watcher AZ-GTi can carry the Celestron NexStar 5SE tube steadily, from the published tube weight and mount payload.
- Optical tube weight
- 6 lb
- Mount rated payload
- 11 lb (a compact WiFi GoTo altazimuth mount rated for a light instrument payload)
- Tube as share of payload
- 55%
- Dovetail
- Vixen-style, matching this mount head
Comfortable fit. The Celestron NexStar 5SE tube weighs 6 lb, well inside the Sky-Watcher AZ-GTi rated payload of 11 lb, so the mount carries it with margin for a diagonal, finder and eyepiece.
A mount's rated payload is for the whole instrument, not just the bare tube. The Celestron NexStar 5SE tube is 6 lb, which is 55% of the Sky-Watcher AZ-GTi 11 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. A compact wifi goto altazimuth mount rated for a light instrument payload.
