iOptron Extends Its Range of Astronomy Camera Mounts with iOptron SkyGuider Pro

Four years ago, iOptron introduced the SkyGuider; which quickly became a tool of choice for serious astro-scape and wide-field astro-imaging. Since then, there has been an explosion of interest in this popular genre of outdoor photography. As users’ imaginations pushed existing tracking devices to their limits, iOptron designers recognized it was time for the next generation camera tracker, introducing the iOptron SkyGuider Pro.

More recently, iOptron introduced the SkyTracker Pro, a compact tracker that weighs just 2.53 pounds (1150 grams), including its equatorial base, and has a payload capacity of 6.6 pounds (3 kilograms).

By comparison, the all new SkyGuider Pro camera tracker weighs 3.2 pounds (1.45 kilograms), including its base (and battery), and has a payload capacity of 11 pounds (5 kilograms). It offers high-precision silent tracking, built-in rechargeable power source, ST-4 guiding port, and a port to connect an optional hand controller.

SkyGuider Pro’s improved precision polar scope maintains a fine engraved reticule and features adjustable illumination. You can even use it with iOptron’s smart phone app, for quick and accurate polar alignment. The Dec mounting bracket allows you to balance a heavy camera and/or lens better, or even mount a light telescope or second camera.

The SkyGuider Pro features four tracking rates: (1) 1X or sidereal, (2) 1/2X for sky and landscape, (3) solar and (4) lunar. All four tracking rates function in both northern and southern hemispheres. iOptron has also added a bi-directional quick-slew mode to help quickly reframe your image without disrupting the camera’s position. It’s removable alt-azimuth base features a precision bubble level, degree markings for the altitude and fine-tune adjustments for both the alt and azimuth axes. You can also mount the SkyGuider Pro head (without the base) directly to any standard photographic tripod with 1/4-20 or 3/8-16 threads.
