    Comments about Celestron NexGuide Autoguider:

    The issue NexGuide buyers understand is that CCD-based equipment is not owned, but held hostage by expensive PC software, licenses, and planned obsolescence. With hundreds of dollars in PC's and software just to operate them, a failed PC or an inevitable OS update means its life is over. Prepare to entertain laughter in response to queries pertaining to the rescue of "antique" electronic software.

    The Nexguide is all about analog adjustment. If you are unfamiliar with traditional analog equipment requiring human touch and hand-eye feedback, this is not for you. If you hate virtual idiot buttons driven by expensive software that is out-of-date in the box upon arrival, then this is the logical choice. If you threw away your electric two-speed focuser because it was easier done by hand, then this is definitely you. Traditional and familiar focus, gain, noise, zoom, alignment, frame duration, and brightness adjustments, all impact accuracy and must be done by hand using the controller and turning a knob. There is no effective whiffing at a field of stars and pressing an idiot button on a screen to get it autoguiding. This is good old-fashioned tuning.

    The 5.6 x 4.7 pixel micron size compares favorably to Orion's Starshoot 5.2 x 5.2 resolution. The Nexguide is also a feather: literally negligible in weight. Maybe a couple ounces.

    I have had considerable success with Nexguide coupled to an Orion ST-80 guidescope, main imaging through a 10" SCT, using an f/6.3 reducer / corrector (63x) for ten minutes at a time. See attached photo of M17.

    It's main drawbacks are an easily scratched LCD display, hot pixels, of which will be seen as stars by the autoguider, convinced it is perfectly guiding while it does nothing. Just put a real star in the neighborhood, and it will work.

    Pros

    • Don't Need Laptop

    Cons

    • To Much To List

    Best Uses

    • Astrophotography

    Comments about Celestron NexGuide Autoguider:

    Cable are to stiff. Menu keeps jumping out of mode. The setup to time comsuming. The hassle you have to go through to find and lock on a star. After you start guiding you hope that it doesn't lose the guiding star while taking a exposure.

          Comments about Celestron NexGuide Autoguider:

          Once you figure out how to properly lock on a guide star, the NexGuide tracks great! Sensitivity requires a somewhat brighter guide star for best results. I've recommended this unit to several folks. A great buy!

          Comments about Celestron NexGuide Autoguider:

          This is a great product for the price. Does what it's supposed to do (track stars for long periods) for astrophotography. I put it through the paces, and it stayed spot-on aligned for long 15 minute exposures with no noticible pixel drift in my images. And it doesn't require a laptop! Who could ask for more from a well priced entry level autoguider!
