iOptron SkyGuider Pro Mount Head with Base


Notice - This package variant is listed on iOptron's website, but they don't sell it in this configuration, therefore we cannot supply this configuration. Please consider buying model #3550 Skyguider Pro Full Package or #3550A Skyguider Pro Full Package with iPolar instead.

Introducing The SkyGuider™ Pro -- iOptron’s next generation camera tracking device! Leading the camera tracker market for nearly four years, iOptron's SkyGuider™ Pro pushes closer to perfection.

The redesigned SkyGuider™ Pro mount head is more compact; small enough to fit on your palm. It delivers better precision, silent tracking, built-in rechargeable power source, ST-4 guiding port and camera trigger port. The improved precision polar scope maintains a fine engraved reticule, now features adjustable illumination with different brightness levels. Using with our iOS app, quick and accurate polar alignment is just a joy.

The SkyGuider™ Pro features four tracking rates, 1X or sidereal, 1/2X for sky and landscape combined, solar and lunar. All 4 tracking rates work in both northern and southern hemispheres. We have also added a quick slew mode with both forward and reverse to help quickly reframing your image without disrupting the cameras position.

We have made big improvements on the SkyGuider™ Pro’s removable alt-azimuth base, which features a precision bubble level, degree markings for the altitude and a built in post for the azimuth control. You can also mount the SkyGuider™ Pro head (without the base) directly to any standard photographic tripod with 1/4” or 3/8” threads.

The SkyGuider™ Pro is certainly a must have tool for any photographer interested in astroscape or wide field astrophotography.
