Telescope Celestron NexStar 90SLT 213x Black Steel Tripod

The Celestron NexStar 90SLT 213x Black Steel Tripod is a compact computerized refractor telescope designed for hobbyist astronomy and daytime spotting. Offering up to 213x magnification and delivered on a preassembled adjustable steel tripod, the instrument combines portable construction with motorized GoTo pointing. The NexStar 90SLT supports SkyAlign automated alignment and is powered by internal AA batteries or an optional AC adapter, enabling rapid setup without tools and cordless operation for field use.

Advantages

This telescope provides a balance of optical power and portability: a 90 mm refractor optical tube produces clear views of the Moon, planets and brighter deep-sky objects while the steel tripod gives stable support for observing sessions. The computerized NexStar GoTo system simplifies object locating and tracking via the ergonomic hand control, and the internal battery compartment powers precision servo motors to minimize vibration and eliminate external cable clutter. Quick-release fork arms and tool-free assembly make deployment fast for both night and land-based use.

Suitable for

• Beginner and intermediate amateur astronomers seeking a portable GoTo telescope
• Planetary observation: Moon, Venus phases, Jupiter and its moons, Saturn’s rings
• Casual deep-sky viewing of brighter nebulae and star clusters
• Daytime spotting and terrestrial observation

How to use

Set up the preassembled steel tripod on firm, level ground and attach the optical tube to the quick-release fork arm. Install eight AA batteries in the internal compartment or connect an optional AC adapter. Power on the hand control and follow the SkyAlign procedure by entering date, time and location, then slew to any three bright objects (stars, Moon or bright planets) to complete alignment. Use the hand control to select catalog objects, adjust slew speed and engage tracking. For terrestrial use, point the scope at a distant landmark and refine focus using the focuser until the image is sharp.

Usage recommendations

For best results, allow the telescope to cool to ambient outdoor temperature before observing, use stable footing or a level pad for the tripod, and select eyepieces appropriate to desired magnification—lower power for wider fields and brighter targets, higher power for details on the Moon and planets. Keep spare AA batteries or an AC adapter available for extended sessions, and perform SkyAlign each observing session for accurate GoTo performance.
