Having difficulty to polar align in the Southern Hemisphere? iOptron has a solution: the SkyGuider Pro with built-in iPolar!

The iOptron SkyGuider Pro is the 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, 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 and now features adjustable illumination with different brightness levels.

Using with iOptron's iOS app, quick and accurate polar alignment is just a joy. The DEC mounting bracket allows you to balance a heavy camera and/or lens better, or even mount a light telescope. The optional 8408 hand controller allows you to check the Pole Star position for the polar alignment, slew the mount, adjust the guiding rate, change the mount settings and control the camera trigger.

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. The new quick slew mode with both forward and reverse helps to quickly reframe your image without disrupting the camera's position.

iOptron has 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 DEC mounting bracket package, which includes DEC mounting bracket, counterweight shaft, counterweight and Vixen-type dovetail saddle, makes the SkyGuider Pro mount suitable for a heavier camera/lens system, even a lightweight telescope.

Note: package does not come with camera, lens, telescope, ballhead or tripod.
