Celestron NexStar 8SE
Classic looks, serious optics: the NexStar 8SE brings computerized GoTo precision to a proven 8-inch Schmidt-Cassegrain.
Performance Scores
Overview
The Celestron NexStar 8SE is built around a 203mm (8-inch) Schmidt-Cassegrain optical tube with a 2032mm focal length at f/10. That aperture puts you in genuinely capable territory: expect sharp views of lunar craters, Saturn's rings and Cassini Division, Jupiter's cloud bands, and Mars during opposition. The long focal ratio also makes it a solid performer on globular clusters and smaller galaxies, though wide-field views of large nebulae will require additional eyepieces. The single-arm fork mount with GoTo computerization is where this scope earns its following.
SkyAlign lets you align on any three bright objects without knowing their names, and the NexStar+ hand controller gives you access to a 40,000-object database that slews and tracks automatically. This genuinely lowers the barrier to finding faint targets. A few honest caveats: the single-arm fork mount is not ideal for astrophotography beyond planets and the Moon. At just under 11kg, it is portable but not lightweight.
The included StarPointer finder is basic and many users upgrade it quickly. At $1,699, this is a meaningful investment, but the combination of aperture, automation, and a well-supported ecosystem makes it a strong choice for a dedicated visual observer ready to move beyond entry-level equipment.

Key Features
- The 8-inch aperture gathers enough light to show globular cluster resolution, galaxy structure, and planetary detail that smaller scopes cannot match
- SkyAlign alignment works with any three bright objects, getting you from setup to observing in roughly 10 minutes
- The 40,000-object GoTo database removes the steep learning curve of star-hopping to faint targets
- Schmidt-Cassegrain design keeps the optical tube compact and manageable despite the large aperture
- Compatible with Celestron's accessory ecosystem, including WiFi adapters and GPS units, so the scope grows with your skills
- The single-arm fork mount handles visual observing well but is not suited for serious long-exposure deep-sky imaging
- A 2-year warranty and US-based support are worth factoring in at this price point

I have owned several scopes over the years: a Meade ETX-90, an Orion 6" DOB, and a Zhumell 10" DOB (which I returned - read on). When I recently renewed my passion for astronomy earlier this year (2010), I started pulling out my little ETX-90 on a regular basis. Unfortunately, the aperture size and ...
I love this scope. It deserves 5 stars, but I would knock one-half star off if I could for the following two reasons: 1. No power supply. You have to buy 8 AA alkaline batteries to use it at all, and they don't last more than a few nights of viewing, depending on how much you move the scope around, ...
This is my second scope. The first was a Bushnell 4.5 inch reflector of disputable quality. The mirror was good, but I had to replace the flimzy tripod and get better eyepieces to even attempt to see anything clearly. This telescope is superior a hundred fold . The image of jupiter, for instance, is...
