My old setup gave me nothing but a tiny circle of light no matter how I held my phone. OptiDock's knobs got the whole moon filling my screen on the first try, and it hasn't budged since.

What our 17,000+ Customers say
Based On Real and Honest Experiences
I run OptiDock on my telescope most weekends. The three-axis knobs get me centered fast, without the flimsy wobble my last clamp gave me, and the build actually feels solid in your hand.
Marcus T.Verified Buyer
I've bought a few adapters chasing that quick, no-fuss setup, and OptiDock is the one that stuck. It's light, low profile, and when I upgraded phones I didn't have to buy a new one, I just moved it right over.

Q1 Will OptiDock hold a big phone like the iPhone Pro Max without sagging?
Yes. The tension-lock system and rugged metal frame keep even large phones like the Pro Max locked tight against the eyepiece, so it stays centered instead of sagging mid-shoot.
Q2 How fast can I get set up?
In about 30 seconds. Simply twist the X, Y, and Z axis knobs until your camera aligns perfectly with the eyepiece, and you're ready to shoot right away.
Q3 Can I use this with my kids' microscope for school projects?
Yes. OptiDock clamps onto microscope eyepieces the same way it does telescopes and binoculars, so your kids can save and share what they see under the lens for a school project.
Q4 What eyepiece sizes does it support?
OptiDock clamps onto eyepieces from 35mm to 60mm in diameter, which covers most spotting scope, binocular, telescope, and microscope eyepieces on the market.
Q5 Do I need to take my phone case off first?
Most cases fit just fine. If yours is unusually thick or bulky, we recommend removing it for the cleanest camera alignment.
Q6 How long does the first alignment take, and does it stay locked in after that?
First-time alignment takes about 30 seconds using the X, Y, and Z knobs. Once the tension-lock is set, you can pop your phone on and off without redoing the alignment on every trip.
Q7 How stable is my phone once it's mounted?
Extremely stable. The tension-lock system and rugged metal frame keep your phone completely still throughout your entire imaging session.
Q8 Is OptiDock sturdy enough for hiking, wind, and rough field use?
Yes. The rugged metal frame and tension-lock clamp are built to ride in a pack and handle wind and knocks in the field, not just a shelf at home.
