Description

The GEM28 is designed with portability and convenience in mind, weighing in at only 10 lbs it can support up to a 28lb payload an incredible 2.8 mount weight to payload ratio. iOptron achieved this using design methods developed to reduce mount mass in our CEM family of mounts. The German EQ versions were created to satisfy consumers that prefer a more traditional mount and to function at higher latitudes.

Building on the legacy of earlier GEM models we have added features for convenience and functionality. A positive lock gear engagement system (easy to use even when wearing gloves), Built-in Wi-Fi enabling unparalleled connectivity and recordable permanent periodic error correction (PPEC) to repeat optimal PEC training sessions. Regarding functionality the GEM28 delivers precise pointing and accurate tracking. The GEM28 sets the new standard for compact German equatorial goto mounts.

The GEM28 is equipped with the latest advanced GOTONOVA® GOTO technology, making it one of the most powerful and accurate GOTO mounts available. The 212,000 object library ensures you’ll never run out of targets to see or image. The Go2Nova® Hand Controller is intuitive to use and its large 4-line LCD screen simplifies the process of setting telescopes and locating objects.

Great For Michigan Fans!
Color: Michigan Wolverines, Style: Goal Post Chew Toy
I got this toy for my puppies and it’s been a hit! Not only does it look great with the Michigan Wolverines design, but it’s also really durable. My dogs love chewing on it and it’s holding up really well despite their intense chewing. It’s the perfect way for any Michigan fan to spoil their furry friends while showing some team spirit. Definitely recommend it for dog owners who want something tough, fun, and stylish for their dogs!

Field Goal MISSED
Color: Kentucky Wildcats, Style: Goal Post Chew Toy
Got ripped off on this one. I missed or they lied about this product IS MADE IN CHINA. The school logo washed off in water when I first received before giving to dog. Gave to dog and she took one sniff and one bite and walked away. After a week of laying with dog chews, I threw it away.

Subpar manufacturing
Color: Penn State Nittany Lions, Style: Goal Post Chew Toy
We bought one of these dog toys in Happy Valley and our dogs LOVED it. I purchased two on Amazon and am disappointed with the shipment. One toy was 1st quality. The second one was in packing that was stapled back together and what we found was the toy was subpar. There were sharp pieces left from the molding process. I’m not sure how this wasn’t caught in the manufacturing process.
