Hey folks, guess what? Building on the rockstar reputation of the iOptron CEM60, we're jazzed to roll out the next-gen medium payload champ, the CEM70EC2W. Why should you care? Because this beast is the first of its kind to boast dual axes high-res encoders, upping your tracking game while making your setup way more portable.
We've kept all the good stuff that comes with a center-balanced equatorial mount, which means this beauty still packs a punch when it comes to efficiency, accuracy, and portability. It's your go-to buddy whether you're eyeballing the skies or capturing breathtaking astro shots.
Peek under the hood and you'll find some awesome perks. We're talking about a built-in iPolar electronic polar scope, gear levers so easy to use you can handle 'em with gloves on, and a snazzy cable management system that covers your mount, iPolar, guider, and camera. Yeah, we thought of everything.
