iOptron CEM70G Center-Balanced Equatorial Mount
with Built-in Guiding System, WiFi & USB3.0

The CEM70G is the decked-out version of the iOptron CEM70!  Besides all the features listed below, the iOptron CEM70G includes the iGuider, an onboard guiding system that will increase tracking accuracy!  It also comes standard with internal WiFi and three USB3.0 ports, which you can see if you take a look at the close-up image above.  This medium-payload computerized equatorial mount is CNC-machined and can handle up to a 70 lb. payload, but is still portable enough (the CEM70G weighs about 30 lb. without counterweights) to take to dark-sky observing sites or set up in your back yard. An optional LiteRoc tripod is available for the iOptron CEM70G, or you can mount it on the pier of your choice. The mount itself comes in a hard case to provide safe storage at your home or on the road.

The iOptron iGuider is built into the dual saddle plate.  It includes a 120 mm focal length guide telescope and a mono camera with a 1280 x 960 array of 3.75 micron pixels.  As mentioned above, the iGuider has three USB3.0 ports for more power and greater speed.

iOptron has taken great care to make sure the CEM70G electronics produce very precise pointing and tracking. It comes with 151 mm RA and Dec worm wheels with 248 teeth each, a 21.2 mm worm, and a 1.8-degree stepper motor with 128 micro-step capacity. Tracking accuracy is stated at <+/-3.5 arc seconds.

The iOptron CEM70G comes with the Go2Nova 8407+ hand controller, sporting a HUGE database of over 200,000 objects! It also comes with an internal iPolar electronic polar scope for super easy polar alignment and an advanced cable management system to keep everything tidy without hang-ups. There are two DC12V (3A) ports, three USB3.0 ports, one DC in and two DC out ports, & one iPort that lets you connect the computer, iGuider, iPolar and other equipment with just one USB line through the cable management panel. 

Other cool features of the CEM70G mount include Park & Zero position, Meridian flip, GPS, and as mentioned above, a hard case! If you have looked at case prices recently, you'll know that this saves you lots of money! Remember, the tripod is optional, even though images may show the mount sitting on one!
