Celestron NexStar 6SE
Six inches of Schmidt-Cassegrain light-gathering power, automated GoTo precision, and a design proven over decades of clear nights.
Performance Scores
Overview
The Celestron NexStar 6SE is a solid choice for intermediate observers who want serious optical performance without hauling a full observatory setup to a dark site. The 152mm aperture and f/10 focal ratio make this scope genuinely capable across a wide range of targets. On the Moon and planets, you can expect crisp views of lunar craters, Jupiter's cloud bands and the Great Red Spot, Saturn's rings and Cassini Division, and Mars's polar caps when the planet is well-placed.
For deep-sky work, globular clusters like M13 resolve beautifully into individual stars, and galaxies like M31 and M81 show real structure. The computerized GoTo mount handles the navigation burden, which matters more than beginners often expect. Once you complete the three-star SkyAlign process, the mount slews accurately to over 40,000 objects and tracks them as Earth rotates.
This keeps targets centered during extended viewing sessions and astrophotography attempts. Worth noting honestly: at 9.5kg, this is portable but not lightweight, and the single-arm fork mount has limits for long-exposure astrophotography. For visual use and short planetary imaging sessions, though, it punches well above its size.

Key Features
- The 6-inch aperture resolves fine planetary detail and shows structure in bright deep-sky objects like globular clusters and galaxies
- Schmidt-Cassegrain design keeps the optical tube compact, making transport and storage realistic for a scope this capable
- SkyAlign lets you align using any three bright objects, so you are not dependent on memorizing star names before your first session
- The NexStar+ hand controller stores a 40,000+ object database and drives the mount automatically once aligned
- Accurate tracking keeps objects centered during extended viewing, which reduces fatigue and improves the experience considerably
- Compatible with Celestron's accessory ecosystem, including the StarSense AutoAlign upgrade and WiFi adapter for smartphone control
- The single-arm fork mount is adequate for visual use but limits serious long-exposure astrophotography, something to weigh if that is your goal

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...
