Introducing The SkyTracker Pro -- iOptron s next generation camera tracking device! Check out the review by Astrobackyard.com https://astrobackyard.com/ioptron-skytracker-pro-review/ Upgraded from SkyTracker, the Pro is more compact, small enough to fit on your palm, better precision, silent tracking, it even has a built-in rechargeable power source that runs for over 24 hours of continuous operation. The improved precision polar scope maintains a fine engraved reticule, now features adjustable illumination with eight brightness levels. Using 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 reframing your image without disrupting the cameras position. We have made big improvements on the SkyTracker 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 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.
