Product description

Enjoy your telescope without batteries with this AC adapter! When using your telescope at home or near any wall outlet, you can enjoy hours of uninterrupted observing. Running your telescope off of AC power is hassle-free and much more reliable than other methods, especially in cool temperatures, when batteries can lose charge quickly. This 2.5 amp AC Adapter is compatible with the following Celestron computerized telescopes: LCM Series, NexStar SLT Series, NexStar SE Series, SkyProdigy Series, Advanced Series, Advanced VX Series, CPC Series, CPC Deluxe HD Series, CPC Deluxe HD Series -This adapter is sufficient for most visual observing with a balanced telescope. However, for astroimaging using additional equipment, the 5 amp adapter (product #18780) is recommended.

    IMO this should have just come with the telescope. It's absolutely a MUST-HAVE. Using batteries is a joke.

    This thing broke when the mount SLIGHTLY tugged on the cable while slewing to a target. This is VERY cheaply made. Do yourself a favor and buy a 12v adapter from motormaster or any other hardware brand for literally half the price.

    Batteries may be more convenient but are very expensive (good ones) and unfortunately rechargeables can also be a pain as well. If mains electric is available this is a good price for what appears to be a good product. Working a treat at the moment and would happily buy again!
