The NexStar Evolution 6 150mm Schmidt-Cassegrain Telescope from Celestron is a powerful, portable, versatile, and user-friendly telescope that can be used for observing everything from the Moon and planets to deep-sky objects like galaxies and nebulae. Using Celestron's proprietary StarBright XLT multi-coating system, light transmission is increased throughout the entire optical path with antireflection multicoated lenses, highly reflective multicoated mirrors, and four-element rare-earth glass. While the focal ratio is a slow f/10, the scope's precision tracking system allows it to be a competent astrophotography/imaging platform for the Moon and planets.

The Evolution comes with two ways to use and control it. The first is to simply download Celestron's free Navigator app for Android and iOS smartphones and tablets. The scope's Wi-Fi provides the connection to the app and expands the capabilities and functionality, including an expanded database of over 120,000 objects with detailed information on more than 200 of those objects. Second is the iconic 2-line, 16-character NexStar computer controller. This is a wired piece of hardware with a database of over 40,000 celestial objects plus several astronomical catalogs including the Messier and Caldwell. Whether using the controller or mobile device, the system can assist in properly aligning the scope, provide tours of the objects and events visible whenever and wherever you're viewing, and allow for manual direction and slew control.

Designed for portability, the Evolution features a long-life lithium-iron phosphate battery providing up to 10 hours of continual use on a single charge. The scope comes with an AC power supply with plugs for the US, EU, UK, and AU outlets. The battery powers the servo motors, auxiliary accessory ports, a USB charging port, and the built-in Wi-Fi. Manual clutches in both altitude and azimuth enable you to manually move and point the telescope when it's powered off.

Q: 5. can this telescope hand control take a motor control update ?

A: It can be up graded if Celestron offers a software update later on.

Q: 6. Does this scope continuously track an object?

A: Yes it does. It has an alt-azmouth mount (up/down, left/right). You basically have to triangulate it with the right time and date so it knows your exact position on earth, and then it will track anything you're looking at. The process is easy -- pick three bright stars and center on each one in succession, and it will triangulate itself and you're good. It takes about 5-10 minutes.

Q: 7. What is the eye relief measurement of the 25mm eyepiece that comes with the 6SE?

A: Eye relief for the 25mm Plossl eyepiece is approximately 17mm.

Q: 8. What is the AFOV on the included eyepieces?

A: On the 40mm eyepiece Apparent Field of View 43° Sorry could not find any information on the 13mm eyepiece.
