5.0 out of 5 stars A Basic Necessity, June 26, 2009

The bottom line on Celestron's SE series is that battery power is not enough. AA batteries drain quickly, and if you are using a dew zapper (also a necessity on SCTs) then that alone will drain your battery is just four hours on Celestron's smaller power tank. Plug your scope in, and the drain is even faster. If you're planning to be out for any length of time you should really consider this accessory. I use it with my 8" SE nearly every time I am out and can plug into a power source. It's never failed me yet.

I ordered the adapter so I wouldn't go through so many batteries when using our telescope at home. It was a great purchase and well worth it. As with many battery operated items, as the batteries get used, the device they power starts to slow down. This is the case with our celestron telescope. Not only does it slow down, when the batteries get to a certain point in their use, the star tracking functions stop working correctly. So, even though the 'scope has power to move, it's slow and and won't follow the star tracks. Not only that, but it won't even correctly star align on start up. But, with the power adapter, that's no longer a problem. The built in functions of the 'scope work perfectly and the 'scope moves with authority when changing from one object to another and correctly stays fixed on the object as it moves through the sky.
Any drawback would be having to connect it to an electrical cord and make sure you don't trip over it, but that's a minor problem. I'd definiately recommend this to anyone with a 'scope.

I ordered a Celestron NexStar 4 Telescope for my husband as a Christmas present. After researching Amazon's site for other related products I found the AC Adapter. This is a must have for any of the Celestron telescopes along with the battery pack. I appreciated that the information was so easy to find and the telescope along with the AC Adapter was delivered on Christmas Eve only 5 days after my order. Thank you Amazon!
