iOptron SkyGuider Pro Camera Mount Full Package Introducing the iOptron SkyGuider Pro -- iOptron’s next generation camera tracking device! Leading the camera tracker market for nearly four years, iOptron's SkyGuider Pro pushes the technology even closer to perfection. The redesigned SkyGuider Pro mount head is more compact, small enough to fit on your palm. It offers better precision, silent tracking, built-in rechargeable power source, ST-4 guiding port, and a camera trigger port. The improved precision polar scope maintains a fine engraved reticule, but now features adjustable illumination with different brightness levels. 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 iOptron SkyGuider Pro camera tracking mount 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. There is also a quick slew mode with both forward and reverse to help quickly reframing your image without disrupting the camera's setup. iOptron 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 the industry standard 1/4” or 3/8” thread bolts. The included DEC mounting bracket package, which includes DEC mounting bracket, counterweight shaft, a counterweight, and Vixen-type dovetail saddle, makes the SkyGuide Pro mount suitable for a heavier camera/lens system, even a lightweight telescope! Includes a soft carrying bag. The SkyGuider Pro from iOptron is certainly a must have tool for any photographer interested in astroscape or wide field astrophotography. NOTE: As shown in the photos, the camera, lens, telescope, ballhead and tripod not included with this product! (These optional items are shown to illustrate possible applications for this product.)
