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.

Used it for a week and it powered my Sony FX30 for whole day via USB C :)

This battery is brilliant. It powered a Blackmagic Pocket 6K for over 12 hours, shooting a mix of 6K 24 and 50. I finished the day on an 18% charge. game changer. No more box loads of NPF batteries

now have 6 lamps with almost identical function and size to this lamp, so I will refer to my experiences with those lamps for comparison. This is a small battery LED (bi-color and fully RGB) with probably the coolest design of all the lights I have, and very simple operating modes. This version of the light is stealth black on black on the back so if someone tries to use it the first time it's hard to read what each button does, but it looks cool and doesn't have the bright white paint if that happens in the picture. I would like the scrolling of the buttons to provide faster action (e.g. it takes a while to scroll to 100% or to 1%) and I feel like the brightness isn't as strong as some of my other similar lamps, but the color temperature measures very accurately and the battery seems to last very well. I have pictured the LEDs at 4000K with 1% brightness to show the number of LEDs and arrangement. I've owned MANY K&F products over the years, including tons of ND and VND filters, tripods, etc., and these lights fit the same high-end build quality as the other K&F products. There are two magenta on the back that you can slightly see through the transparent back. They hold REALLY well on nice flat metal surfaces, but even on a round post they can hold if placed properly. It comes with 1/4 20 screw holes on the top and bottom, and a 1/4 20 cold shoe holder is included. It's worth noting that there is no cold shoe slot built into the lamp itself (for stacking lamps), so you'll need a 1/4 20 to 1/4 20 screw to connect two together. Not a deal breaker, but I often plug my lights in during storage to keep them all together. The overall performance is great, and the build quality and style (if that matters) can't be beat. These are beautiful lights!

This is not my first video light, and I’m sure this is a good video light. Color of RGB can be changed easily and the battery last relatively long, at least 2 hours as I tested. Will buy the second one if needed.

As someone who makes YouTube videos, I’ve accumulated a lot of little RGB lights over the years, but this is by far the coolest, I’ve seen. The overall design is similar to what you’re used to in that it has a CCT mode, RGB mode and some pre-set scene modes, but it’s the overall execution of how these are employed that really sets this little light apart from the others. The style is quirky and cool. It comes in a package that literally looks like a box of tofu. And where others would have boring buttons or sliders, this light uses giant knobs on the side have a fun retro-modern kind of vibe that actually work just as good as they look. From the bottom knob, you can switch it on, turn to CCT mode, RGB mode or the scene modes. The top button allows you to change the intensity of the settings in the various modes, i.e.: brightness, saturation, etc. And of course there’s a magnetic back and not one, but two tripod mounts - one on the bottom and one on the top. This is a really well-designed little RGB light that stands out in a crowded market place of similar lights. This light both looks great and works great - definitely would recommend.

A lovely pocket battery powered microscope it comes with travel bag, cloth and preprepared microscope slides. Good level of focus and zoom control means I can get a clear detailed up close view of things with my children.

I say this is the first battery powered camera I've bought. I was skeptical but pleasantly satisfied.
It is made of materials that are comfortable to the touch and feel sturdy in the hand.
Movements that can be controlled via the app are smooth and precise.
The battery lasts a long time, and the remaining power is more than sufficient even on days without sun or rain.
The clip to be attached to the wall facilitates installation, the same applies to the solar panel.
I can absolutely recommend the purchase! !
