![]() ![]() Celestron’s main explanation is that many beginners would buy the bracket and attempt to fit it onto substandard telescopes (or simply do it improperly) and become frustrated. Many people have asked on astronomy forums and contacted Celestron themselves, asking why the bracket and code cannot be sold as a stand-alone item. This is much less precise than a real GoTo system with tracking but much simpler, easier, and more reliable than a motorized telescope. ![]() In practice, this system is limited to an accuracy of a bit better 0.25 degrees, or half the width of a full moon. Instead, it occasionally uses plate-solving technology when you first set up the telescope or move it across a significant portion of the sky, then tries its best to extrapolate finer movements using your phone’s relatively inaccurate gyroscope and accelerometer. Thanks to your phone’s limited battery life and computing power, the StarSense Explorer technology obviously can’t take a new picture of the sky every time you move the telescope. Read why we prefer High Point Scientific to Amazon In principle, the StarSense Explorer tech is basically a bracket to point your phone at a small mirror that has been aligned to the telescope mount, and then uses the phone’s onboard camera and processing power to plate-solve.īuy From HighPointScientific Buy From Amazon Normally, this is done for astrophotography to avoid performing a time-consuming GoTo alignment and is only used to find one target. In essence, what it does is take a snapshot of the sky and use computer algorithms and star maps to figure out where it is pointing. The StarSense Explorer Technology & AppĪt its core, the StarSense Explorer actually uses a relatively old technology known as plate-solving. A pair of flexible slow-motion cables are included for making fine adjustments, though the backlash from them can be annoying when using high magnifications, and it’s not as intuitive as a simple Dobsonian mount, for instance. The accessory tray is a nice, sturdy affair and an actual tray rather than the silly eyepiece rack supplied with many scopes. It’s a simple, aluminum-legged alt-azimuth mount with slow-motion controls on both axes. This mount is a little on the small side for either optical tube, but it works just fine. The StarSense Explorer DX mount is nothing more than a repainted Omni XLT AZ or “AZ3” mount with a bracket for the StarSense Explorer device. ![]()
