This is not an astronomy camera, it's a general purpose battery-powered, image-stabilized audio/video color camera. It communicates with your smartphone or tablet via WiFi. I dreagged out a rescued-from-the-trash 102mm el-cheapo refractor, clamped the camera on its eyepiece, and quickly focused on a fake windmill three miles away. I also tried shooting right into the low-angle sun glare in the ocean and the camera didn't blink (like I did)--the automatic gain control took it in stride. Mind you, the telescope made things seem close, not the camera--all it does is replace your eye. This is good because that means you can clamp it onto anything you might look through, such as a riflescope or microscope, or even just point it out the window. Set up is a little fiddly, but if you've hooked up a camera with its own WiFi hotspot it will be a snap. Select the camera wifi hotspot in your camera's settings and then use the app. In short, if you like cool stuff, this is well worth the money.

If you or someone you know is really into astronomy and/or astrophotography, but is past the beginner's stage, this is getting will get you through the amateur stage. We have used this to view the eclipse, UFO landing on the moon (just kidding) and the mountain peaks near us. And taking pictures with our iPhones is a great memory.

I have taking this to my children's school for STEAM events.

This is a cool little instrument that would be good for electronically assisted astronomy or for a public outreach. The sensor isn’t the biggest and I couldn’t fully frame the moon, about 85%, with a 60/360 telescope. With adjustable exposure you could most likely see some nebula with it. A longer cable would be nice to connect to an outside power source, such as your laptop.

I bought this tripod to mount my Celestron 20x80 astronomy binoculars on. It works great! I'm 6"5" tall and I can stand at full height and use the tripod with the binoculars mounted on it. It's easy to move the binoculars up & down and side-to-side. I couldn't believe the flexibility the tripod provides in height adjustment. Definitely worth the price.

We just love this binoculars!

add a clarification on the product after use. I'm very happy with the Nikon 35 1.8DX on this adapter.. which I thought was a bit thick.. I expected some loss of brightness. Since there is nothing in the product details, I tried to ask K&F about it: no answer... :( Well, I did the measurements myself... with the same aperture on a sensor with the same resolution, we go with the adapter from 1 /800 to 1/500.. so 3/4 of an additional f-stop my 1.8 Nikon becomes a 2.2... a 2.8 becomes a 3.5 the product is excellent but good to know this loss of brightness ( would have liked to see it noted). As with the extended rings, the lens attached does not lose any sharpness I was waiting to receive it, at least not expecting the best... Surprise; the product is heavy, well finished (I have already extended All plastic rings) I grab my XM1, I pull out my fixed AFD focal lengths... the 24... that becomes a 36... and the 35/2 a 53mm my first attempts at shooting don't work: he you have to Select "shoot without lens" in the xm1 settings, I continue to shoot, excellent the system of" ; "Rand" on the screen when the MAP is ready, (I tested at 1.8-2 to verify this map, on the computer the map is actually correct). The contrast system is only really apparent at a wide aperture... As with some old cameras, open the aperture card wide and stop before shooting with other cameras in range that also have viewfinders. It might be easier to focus manually: the ring also allows you to do glare, you do that "at your discretion", but it's great to have. The 35 1.8Dx is very good at 1.8 for anything that doesn't need an ultra-fast card (j) I've tried portraits of my dogs... that move... well, manual focus on the XM1 screen remains quick and accurate ), for anyone who has a quality focal length stash that doesn't want to buy new ones that aren't necessarily better in terms of sharpness (no choice on Xmount Mount). I recommend this ring in addition, very affordable I am very happy with this surprise purchase, all my Nikon lenses are reworked with this camera

Filter used on a sigma 24-35. Very practical in variable to make long poses during the day.

I was looking for a filter of this type not too heavy because this kind of photo is not my primary activity. This K&F Concept ND Filter is perfect and not too expensive!

These binoculars are brilliant.
