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.

Looks amazing!
Size: 4-tier, Style: wall mount&floor mount, Size: 4-tier, Style: wall mount&floor mount
Very straight forward to build. Mine was not hard but to a bit more effort because my ceiling is at an angle so I had to get a little creative. I cut a piece of wood and placed it between the ceiling and one of the arms for it to be even. It’s also not completely even cause I didn’t have a long level but still looks amazing.

Very easy to put up and assemble!
Size: 48 inch 3 Tier, Size: 48 inch 3 Tier
We were looking for a nice shelf over our coffee bar, and this industrial pipe shelf was perfect! This was very easy to assemble! Simply put in your anchors and screw in the bases! We ordered the three tier shelf but only needed two, and it was very easy to make that adjustment! I loved that this was solid wood shelving rather than particle board.

beautiful and sturdy
Size: 48 inch 2 Tier
The shelf is beautiful and sturdy. The only small complaint are the instructions to put it together are deceiving because pieces were put together for shipping purposes (we assume) but didn't actually go together which took us a few times to figure out. I recommend putting it together off the wall before trying it on the wall so you know what pieces go where.

Cheaply made
Size: 48 inch 2 Tier
I would not recommend this shelf. There are no instructions included - just a simple drawing of putting it together but nowhere says what drill bit size to use for the plastic anchors which are square on the end and not round. In addition, you cannot fully tighten the iron brackets or they won’t alight on the wall to hang the shelf. Each piece of metal piping has part of the black coating stripped off as well. And on top of that, the bottom of each shelf is unfinished and looks as though they used a filler to hide holes in the shelf. Not worth the money or the hassle.
