Celestron NexStar 8SE “Orange Tube”: the modernized classic
The Celestron NexStar 8SE is one of the most emblematic telescopes in amateur astronomy. Its concept 8-inch Schmidt-Cassegrain revolutionized the market in the 1970s thanks to a rare balance: a lot of openness, an instrument compact and use simple.
This “SE” version takes up the iconic design orange tube by adding modern functions (GoTo, database, rapid alignment) to offer a premium experience for beginners and experienced observers alike.
Why it's excellent (even as a first “real” telescope)
- Ouverture de 203,2 mm (8″) High light collection to reveal details of the Moon, planets and many deep-sky objects.
- Motorized GoTo the mount automatically points and tracks objects (more time observing, less time searching).
- Database 40,000+ objects planets, nebulae, galaxies, clusters, double stars...
- SkyAlign : set up and align in just a few minutes, even if you don't know much about the sky.
- Portable format design single-arm fork + steel tripod, can be disassembled into separate parts for transport and storage.
- StarBright XLT optics High-quality treatments to maximize transmission and contrast.
What you'll see (in concrete terms)
Thanks to its collecting power 843× that of the eye and fine resolution (Dawes 0,57″), the NexStar 8SE is visually formidable:
- Moon reliefs, craters, faults and fine structures “like never before”.
- Planets Cassini's division of Saturn's rings, Jupiter's cloud bands, and atmospheric details depending on conditions.
- Deep sky These include globular clusters (e.g. Hercules), galaxies (e.g. Whirlpool / M51), and a wide variety of objects accessible from a suitable site.
GoTo + tracking: observation becomes fluid
The frame alt-azimutale GoTo automatically locates and tracks objects. You choose a target, the telescope moves to it, then keeps it centered. The result: more comfortable observation, especially at high magnification.
- Pointing speeds 9 speeds, up to 5°/second
- Tracking speeds sidereal, solar, lunar
- Modes Alt-Az, EQ North / EQ South (EQ mode possible with wedge)
- NexStar+ Racquets double-line LCD display + base 40,000 items + 200 programmable objects
- Sky Tour the telescope can offer the best visible targets of the moment
SkyAlign: simple, fast, effective
NexStar 8SE uses SkyAlign just center three shiny objects (stars or planets) and then confirm. Even without any knowledge of the sky, alignment takes just a few minutes.
StarSense compatibility (very important)
Yes: the NexStar 8SE is compatible with StarSense® technology (e.g. StarSense AutoAlign). With the addition of this accessory, alignment can be carried out automatically, This further simplifies first outings and speeds up start-up.
Going further: accessories and advanced uses

Safety information
- Sun : never observe the sun with the naked eye or with the instrument without a suitable solar filter. Risk of permanent eye damage.
- Never project the image of the Sun onto a surface through the optics (risk of overheating and damage).
- Never leave the instrument unattended, especially in the presence of children.
