iOptron SkyTracker Pro with Polar Scope

Note: The smaller scale inset image shows the optional counterweight package and optional ball head installed and in its in-use configuration. These items, as well as the tripod and the camera, are not included.

Upgraded from its predecessor, the SkyTracker™, the Pro is more compact (small enough to fit on your palm), delivers better precision, silent tracking, and has a built-in rechargeable power source that runs for up to 24 hours of continuous operation. The improved precision polar scope is equipped with a fine, engraved reticule, and now features adjustable illumination with eight brightness levels. When used with our smart phone app, quick and accurate polar alignment is just a joy.

The SkyTracker™ Pro features four tracking rates, 1X or sidereal, 1/2X for sky and landscape, 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 frame your image without disrupting the camera's position.

We have made big improvements in the SkyTracker™ Pro’s removable alt-azimuth base, which features a precision bubble level, degree markings for the latitude and a built in post for the azimuth control. You can also mount the SkyTracker™ Pro head (without the base) directly to any standard photographic tripod with 1/4” or 3/8” threads. The SkyTracker™ Pro is certainly a must-have tool for any photographer interested in astroscape or wide field astrophotography.
