Celestron Nexstar 5SE Catadioptric Telescope 295x Black Orange

The Celestron NexStar 5SE Catadioptric Telescope 295x in black and orange is a compact, portable Schmidt-Cassegrain style instrument designed for observing planets, the Moon and brighter deep-sky objects. It features a 15.2 cm (5-inch) primary mirror housed in a 330 mm optical tube made from aluminum, paired with the NexStar single fork-arm computerized mount and NexStar+ hand control. The system provides up to 295x magnification with appropriate eyepieces and accessories and is intended for both beginning and experienced amateur astronomers who need a balance of portability, optical performance and computerized object location.

Advantages

The NexStar 5SE combines a compact, durable aluminum optical tube with the convenience of a computerized single fork-arm mount, simplifying setup and transport. SkyAlign-compatible alignment and the NexStar+ hand control give access to a database of tens of thousands of celestial objects and automated pointing and tracking. The 5-inch aperture gathers sufficient light for detailed views of planets, lunar features and many brighter deep-sky targets while remaining lightweight enough to disassemble for travel and storage.

Suitable for

• Planetary and lunar observation
• Visual deep-sky viewing at dark-sky sites
• Beginning to intermediate amateur astronomers learning alignment and computerized tracking
• Portable field sessions and backyard observing

Key specifications

• Optical design: Catadioptric (Schmidt-Cassegrain style)
• Primary mirror diameter: 15.2 cm (5 inches)
• Optical tube material: Aluminum
• Tube length: 330 mm
• Maximum practical magnification: up to 295x (with suitable eyepieces and seeing conditions)
• Mount type: Single fork-arm computerized mount with NexStar+ hand control
• Alignment: SkyAlign-compatible (manual alignment routine)
• Portability: Breaks down into compact components for transport and storage

How to use

Assemble the optical tube onto the single fork-arm mount and balance according to the supplied instructions. Power the mount, perform the SkyAlign procedure by centering three bright objects in the eyepiece and pressing ALIGN, or use a compatible automatic alignment accessory for a hands-off routine. Select eyepieces to achieve desired magnification — lower-power eyepieces for wide-field views and higher-power eyepieces for detailed planetary observation — and use the NexStar+ hand control to select objects from the onboard database or run a Sky Tour. For long-exposure imaging, attach appropriate tracking and imaging accessories and follow the camera manufacturer’s setup procedures.

Usage recommendations

For best visual results, use the NexStar 5SE from a dark or moderately dark site and allow the telescope to reach thermal equilibrium with the outdoors. Start with low to medium magnification to locate targets, then increase magnification as atmospheric seeing permits. Regularly check and tighten mounting hardware before each session and store the telescope in a dry place to protect optical surfaces and electronics.
