Leading the camera tracker market for nearly four years, iOptron's SkyGuider Pro pushes closer to perfection.The redesigned SkyGuiderTM 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, now features adjustable illumination with different brightness levels. Using with our 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 SkyGuiderTM 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 SkyGuiderTM 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 SkyGuiderTM 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 SkyGuideTM Pro mount suitable for a heavier camera/lens system, even a lightweight telescope.The SkyGuiderTM Pro is certainly a must have tool for any photographer interested in astroscape or wide field astrophotography.
