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.

Not the best, but not the worst either
Format: Hardcover
By any means not the funniest book in the series, only the one on Krusty the Clown was more un-funny; but still a worthy addition to your collection and, just like all the others from the series providing a retrospective of anecdotes you might have forgotten.

Not that great
Huge "The Simpsons" fan. I watched all the episodes and read a lot of the comics and enjoy most. This one however was quite boring. Turns out I'm just not a big fan of Chief Wiggum. I really enjoyed The "Homer" and "Bart" book. But not this one. Maybe if you love Wiggum you'll love it. If you're not too fond of him then I wouldn't buy it.
