Overview
The Celestron NexStar 5" SLT is a 125mm Schmidt-Cassegrain on a computerised single fork arm altazimuth mount, built for beginners who want GoTo convenience without a heavy kit. The 1250mm focal length at f/10 and StarBright XLT coatings resolve lunar craters, Saturn's rings, and Jupiter's cloud bands, while the NexStar+ hand control slews to any of 40,000+ objects after a quick SkyAlign on three bright stars. The whole kit weighs 7.3kg, and the pre-assembled stainless steel tripod and quick-release fork arm set up without tools, so you can be observing in minutes.
Key Features
- 125mm Schmidt-Cassegrain Optics – The 5" SCT with StarBright XLT coatings gathers 329x more light than the human eye, revealing lunar surface detail, Saturn's rings, Jupiter's four moons, and brighter deep-sky objects.
- SkyAlign and 40,000+ Object Database – Point the telescope at any three bright objects and SkyAlign triangulates its position without needing to know star names. The NexStar+ hand control then slews to any of 40,000+ objects at the push of a button.
- Computerised Single Fork Arm Mount – A motorised altazimuth mount with 9 slew speeds (max 3°/sec) tracks objects as they move across the sky, with tracking modes for Alt-Az and EQ North/South.
- Lightweight 7.3kg Kit – The entire telescope, mount, and tripod weigh just 7.3kg, making it one of the most portable GoTo SCT kits available and easy to carry outside for an impromptu session.
- No-Tool Setup – The pre-assembled stainless steel tripod and quick-release fork arm assemble in minutes without tools, so you can be aligned and observing quickly.
- Two Eyepieces Included – A 25mm eyepiece delivers 50x for wide-field viewing, and a 9mm eyepiece provides 139x for closer lunar and planetary detail.
- CG-5 Dovetail Compatibility – The optical tube uses a CG-5/Vixen-style dovetail bar, so the tube can be removed and mounted on other compatible mounts if you want to upgrade later.
- 2-Year Celestron Warranty – Backed by Celestron's 2-year warranty for confidence in the field.
Ideal For
- Beginners wanting GoTo convenience in a lightweight package
- Families and students wanting a first computerised telescope
- Users with limited storage or transport space
- Casual observers wanting quick setup for impromptu sessions
- Those wanting a tube that can move to a larger mount later
