Overview

The Celestron NexStar 6SE gives you a serious 150mm aperture in a Schmidt-Cassegrain design that folds a 1500mm focal length into a surprisingly compact tube. At f/10, it excels at planetary detail, double stars, and globular clusters, and it handles many deep-sky targets well from a reasonably dark suburban site. The GoTo system is a genuine time-saver: SkyAlign lets you align on three bright objects without knowing their names, and from there the hand controller can locate and track over 40,000 objects automatically.

The single fork arm mount keeps the whole system under 20kg, and the telescope breaks down into a few manageable pieces, making it realistic to set up and take down in a single session. Wi-Fi connectivity through the SkyPortal app adds wireless control from a smartphone or tablet, which many users find more convenient than the hand controller. Worth noting: the single fork arm design can introduce some vibration at high magnifications, and like all SCTs, cool-down time on warm evenings will affect image sharpness.

For someone ready to move beyond a beginner scope without investing in a full observatory-grade setup, the 6SE is a well-rounded choice.

Key Features

  • 150mm aperture delivers sharp planetary views and resolves tight double stars and globular clusters
  • 1500mm focal length at f/10 suits high-magnification observing without requiring extremely short focal length eyepieces
  • SkyAlign reduces alignment to centering three bright objects, making setup practical even for newer users
  • GoTo tracking keeps objects centered during extended viewing sessions and works well for casual astrophotography of brighter targets
  • Breaks down into compact, independently manageable components for transport and storage
  • SkyPortal Wi-Fi app enables wireless telescope control from a smartphone or tablet
  • Single fork arm mount keeps weight reasonable but may show vibration at very high magnifications

Pics of the moon. Looking like structures

The media could not be loaded. What I did not like was the vibration each time I tried to take a pic. So I set a timer for I think 3s again I used an iPhone as my camera. So the vibration pads are needed. I guess if you’re using your phone as I am. Another problem I’m having is the alignment process...

Incredible Telescope!

I’m a beginner as far as telescopes go and this is an amazing telescope for the price. It was easy to set up and I could see many stars as well as a couple planets on my first try. And that was with horrible light pollution. This is definitely a great telescope for a beginner through an intermediate...

Couldn’t align it

This may be a great telescope, but I’ll never know. I simply could not align it. I called their help desk, but still no luck. I was excited to use it but ended up very disappointed.
