The Celestron NexStar Evolution 6 150mm GoTo Telescopefrom Celestron NexStar Evolution 6 150mm GoTo Telescopeis 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.

Related Questions and Answers

Q: 1. Can you not use Starsense camera, with a Starsense HC, or do you need standard HC?

A: Good morning, If the StarSense autoalign system is used, it is mandatory that the dedicated StarSense hand controller be used for the autoalignment process. However, If the StarSense camera and the autoalign system is not used, the StarSense hand controller can be used to "manually" control the telescope in place of the standard Nexstar Plus hand controller.

Q: 2. Can the telescope be used with the Sky Safari App or only the Celestron SkyPortal?

A: Yes, the NexStar Evolution has the built-in WiFi so you can use that with the SkyPortal app. I can not confirm the use of Sky Safari, as that is another company.

Q: 3. can u adapt 2" eyepiece to it?

A: Yes , of course Lumicon 1.25" Male to 2" Female Drop-In Eyepiece Adapter BH #LU125M2SA • MFR #LA1055 https://www.bhphotovideo.com/c/product/457656-REG/Lumicon_LA1055_1_25_Male_to_2.html

Q: 4. I just received my NexStar 6 Evolution and it appears there are several noticeable particles on the interior mirrors within the OTA. Is this common with new scopes or did I get a bad / poorly sealed version?

A: It is possible. The environment where there are assembled is not 100% dust free. You can return of e refund or exchange

Q: 5. Does this scope come with a hand controller?

A: Yes it comes with the hand controller but I have never used it, I always use the app to control my scope.

Q: 6. What is the package shipping weight and dimensions?

A: Unfortunately we are unable to provide the Shipping Dimensions, and Weight. My apologies. The dimensions of the scope packaged in the manufacturer's box is 43 X 28 X 15 (LXWXH).

Q: 7. Can this telescope also be powered from a mains lead or is it battery only?

A: While this telescope comes with AC adapter for charging, Celestron specifies using only battery power (though not while charging) for the evolution series telescopes.

Q: 8. Can I attach a Canon 6D with a mount to this?

A: Your question is a little unclear. Do you mean attaching the camera on top of the telescope? If so, look at Celestron's universal piggyback mount. You will be able to use the mount to track. If you mean taking photos with the telescope - with the proper attachments, you probably could. The issue that you will come across is shooting near the zenith - I don't think that there is sufficient clearance for a SLR. I would check the forums.

Q: 9. Does the telescope come already in the Hard Case in this kit or do the come separately packed?

A: This question is a double of the prior question.

Q: 10. 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.
