Description
Innovative ideas applied to a time tested design, the iOptron® GEM45 next generation German equatorial mounts. A sharp looking CNC body is the first indicator the GEM45 is a top quality mount in both form and function.
- Utilizing experiences gained during development of the CEM series, iOptron were able to remove unnecessary bulk giving the GEM45 an incredible 2.8 payload to mount weight ratio. This compact 15.8lb mount can precisely GOTO an object and track with up to 45lbs of gear onboard.
- With its integrated electronic polar scope (iPolar), polar alignment is a snap, even when the pole star is obscured.
- Large levers on the quick-lock drive engagement system make it easy to snap its drive gears into place even when wearing gloves. There is little chance of your cables getting snagged with the GEM45's internal advanced cable management system.
- A new, patent pending Universal Self-Centering Saddle (USCS) accommodates Losmandy and Vixen style dovetail plates.
- GEM45 mounts utilize reliable stepper motor drive systems with low power consumption technology.
- A 212,000+ object library with star identification, GPS, optional Wi-Fi (requires iStarFi adapter) are a few of the desirable features standard on a GEM45 mount.
The mount comes with the LiteRoc 1.75" tripod delivers rock solid stability in a lighter, more compact package. It also has improved leg cuffs and sockets for more rigidity and redesigned leg lock levers.

Monkee-doodle loves that it has a crinkle sound when playing tug-of -war
Color: Crinkle Chicken (Yellow), Size: Large
Monkee-doodle likes this toy because it has a squeaker and it also has a crinkle noise maker inside. She loves playing with the toy and it’s easy to spot since it is bright yellow in color. It is suitable for dogs and doesn’t have any pieces that can come loose and harm your pet.

Love it.
Color: Bunny (Beige), Size: Large
Good quality and well worth the price. My dog loves it. The squeaky part is fun, and the crinkly, tear-resistant paper in the ears makes playtime even more exciting.

Perfect size
Color: Mixed Color-20PK
These little balls are too cute. My dog loves tennis balls, but they’re just a little bit too big for her mouth. She also loves golf balls, but I’m terrified she’s going to choke on them. This 2 inch ball is right there in between in regards to sizing. I love that they squeak. They arrived neatly lined up by color in a little box, with the net pouch included. Great purchase for my little pup.
