The ED102 102mm f/7 Essential Apochromatic FCD100 ED Triplet Refractor Telescope from Explore Scientific features a triplet apochromatic lens system with Hoya's exceptionally engineered and crafted FCD100 extra-low dispersion (ED) glass and Explore Scientific's proprietary anti-reflection EMD fully multi-coated optics. This combination of glass, lenses, and coatings virtually eliminates chromatic and spherical aberrations for clear and bright images without distortion across the entire field of view, with true color rendition. This is a versatile optical tube assembly that is powerful enough to clearly see the planets and bright deep sky objects. It has a relatively small form-factor that makes it perfect as a portable grab-and-go option, or set up on a dual-mount rig for astrophotography/astroimaging.

A mounting cradle-ring clamps over optical tube assembly (OTA). The cradle-ring allows the user to adjust the orientation and position of the scope relative to the mount to optimize viewing comfort and balance, while avoiding interference with other equipment. The scope is offered without a mount or tripod, but a Vixen-style dovetail plate makes it compatible with any alt-az or equatorial mount with a Vixen-style saddle. Its two-speed rack-and-pinion focuser helps make fine-focusing fast and precise. A 90� star diagonal is also included for more comfortable viewing. The mirror has dielectric coatings for a 99% light transmission for minimal light loss when using it.

Almost perfect
Color: Black, Size: 2 Large Panels, Color: Black, Size: 2 Large Panels
The cloth material is sturdy and fits well on the design. Both sides are black and you can't tell a difference between each side. It's extremely light weight and easily movable. We got a double and a single and the single is used as a sliding door. It's definitely not the MOST stable thing but overall it's pretty stable, probably won't work GREAT on carpet. It's not see through at all, which is great, the only downfall is the gap between the two sides. We are using a blanket to cover the gap. It's not 6 foot tall, but you can adjust the feet on it to be taller. Overall it's a great product for the price and can easily be moved out of they way.

A decent buy
Color: Black, Size: 1 Large Panel
Easy to assemble, good quality fabric, the two horizontal "feet" are supposed to be stabilized by a knob/screw but its always looosening up with even the slightest move, so the only unfortunate thig is that it requires constant turning to tighten it if you adjust its location even a teensy bit. I used it as a backdrop to hold a design of balloons, then since the party I use it as a "semi" partition in a bedroom. Good value for the money since it can be used over and over.

Inexpensive Solution For Privacy
Color: Grey, Size: 2 Large Panels, Color: Grey, Size: 2 Large Panels
This worked for my needs to get privacy on a second-floor patio that faced neighbors about 16 feet away, and was almost exactly the width and height I need, and was looking for. As the patio was about 12 feet in width. The fabric is thin, but not see-through, and works well enough for my specific privacy needs. It wasn't that sturdy, even with the three legs, the top would kind of bend a bit from the weight of the thing, but I knew this from previous comments on reviews, and opted to use C-clamps and some screws to tighten it to the wall so that isn't an issue since I was outside and had walls to be able to screw into. You may have to try something different if using inside. I gave four stars instead of five as the instructions past Step 3 really don't make much sense for Steps 4 and 5 where the two are connected and when legs are put on, but I was able to work through it eventually. They really need to break down the steps for installing the legs with better illustrations. Also, highly recommend having two people work on it or at least having a second person on standby for certain steps just due to the size of them once they are together or for connecting the dividers together in the end.

Very sturdy & nice looking! Impressive & functional
Color: Black, Size: 2 Large Panels, Color: Black, Size: 2 Large Panels
I needed to divide our living room room in half and create a work room but didn’t want it to be visible so we decided to get this and use it in an L shape. It’s very simple and functional, but it does exactly what I need. I’m contemplating hanging a photograph from a ribbon just to add a little personality to the side that faces the living room room but honestly, it’s much more sturdy than I gave a credit for. I am a full-time reseller so I got foam from the hardware store and covered it in fabric as a background for taking pictures and I have a huge one that’s 6‘ x 3‘ plus another one that’s 4‘ x 4‘ both of which are hanging on the inside of this and it works great. I’m impressed!!

Weigh your options
Color: Grey, Size: 2 Large Panels
It serves the purpose but make sure you stabilize it. It's not a bad product it's extremely light and insecure without something to hold the base in place. Maybe it was just the one I bought but it moved a lotI would just bump it a little and it would fall over. The good thing is It is easy to set up and has versatile usage. Also it's really big. Takes up a lot of space make sure you measure your room first.
