Celestron Smartphone Adapter & Bluetooth Remote for Telescope Eyepieces

Takes some patience. Now performs well.

taken some pretty cool pics with this attachment, like the moon and the sun

Me gustó porque me permitió conectar mi celular a mis binoculares Celestron y capturar imágenes notables, como el faro de Cabo de Hornos, Chile. La instalación inicial requiere algo de paciencia debido a sus tres grados de ajuste, pero una vez alineado correctamente, permite obtener tomas únicas e inolvidables. Un accesorio muy recomendable para quienes desean llevar sus observaciones al siguiente nivel.

Two adult tech savvy people attempted for over an hour to get these adapters to work with Celestron binoculars using Samsung S71 and S22 phones as well as an iPhone 11. It took both pairs of hands to even attempt to mount the binoculars and camera following the included instructions to tee. The concept is amazing but we gave up after the hour and have returned the two adapters. While the part that mounts to the binoculars is metal the adjustment knobs are plastic and one was detached out of the box.

It works nice just need to use it more often

This adapter is difficult to adjust properly and worse, to secure your phone properly, it might end up pressing one or more buttons on your phone! Your phone is held in place by tightening a long threaded bolt screw that slowly opens and closes the phone clasp around your device. The phone is held snugly between soft pieces of foam. It's a very slow process to get your phone in the holder, especially if you have a wide phone. Adjusting the X and Y axis of your phone in the mount is even more problematic. You can't really adjust each axis individually. You essentially loosen a single thumb screw on the back and then you sort of rotate the phone clockwise/counter-clockwise while sliding the phone up and down. If you're able to get it aligned, then you have to tighten the thumb screw without moving the phone at all, or you'll lock it down in the wrong alignment. It's extremely difficult to make fine tune adjustments, and that's even harder if you're trying to do it in the dark. The worst part of this design is that to get your phone camera lens into the proper X-Y position alignment with your telescope/binocular eye piece, you may have to position your phone so that one or more of its side buttons will be pressed down by the foam clamp that is holds the phone in place. There's several problems with this, but the main one is that if it's the power button on your phone, the holder will keep the power button depressed, which will end up rebooting your phone. If multiple buttons are held down, it might even send your phone into the bootloader/recovery screen! I've attached several pictures on different phones, showing what I'm talking about. I've highlighted the buttons that get pressed down by this adapter when the phone is securely fastened into the device and the camera lens is in the proper position so that it lines up with the eye piece on your telescope/binoculars. On a OnePlus 8T, the power button gets pushed down. On a Google Pixel 3XL the power button and both volume keys get pushed down. On an Essentials PH-1, the power button and the volume down buttons get pushed down. On an Asus Zenfone 5Z, the power button and the volume down buttons get pushed down. Instead of wasting your money on this Celestron adapter, you should get an adapter that will actually work. Celestron actually offers a much better model: The Celeston NexYZ adapter (https://amazon.com/Celestron-3-Axis-Universal-Smartphone-Adapter/dp/B07D7V3B8M/). Yes, it is more expensive, but it is far superior in every aspect: 1) independent X,Y and Z fine tunable adjustment knobs, 2) easy spring loaded phone clasp, 3) it actually works, and 4) it won't reboot your phone.

I have a Samsung S21 Ultra and when I line up the camera lens with the eyepiece on my telescope, the clamps hit my phone exactly over the volume and the side key, so when I tighten the clamps it either shuts off my screen or opens the Bixby app. If I don't push my phone all the way in and clamp it down behind the buttons, it stays secure, but then it doesn't sit close to the lens. Frustrating, as I thought it was supposed to be "Universal". It's sturdy and well made, and would probably be great if it didn't turn my screen off when I tighten the clamps. If anybody has any suggestions or tips I would appreciate it.

Worked great , used it to take some pics through my cell phone and 8 inch Dobsonian. Would recommend as a cheap alternative to very high price cameras .

Excelente producto de buena calidad el material y excelente adaptabilidad al telescopio

Kvaliteta

Took a bit to figure out how to put it on but once done it works great. Just need a bit of nice weather to get outside to use. Highly recommend this attatchment. Makes viewing easier

Good

Allows you to secure a smartphone camera over the eyepieces of most binoculars/telescopes with pleny of scope for adjustment. I am using it with Celestron 20x80 binocs. A bit of a faff to get it over the rubber eyecup, but it can be done, And a nice touch is you get a bluetooth remote so you don't have to touch the setup to take a picture, once you have it all lined up.
