Your photos always succeeds:

Two metal clamps hold and centre the eyepiece. So your smartphone's camera lens sits precisely in the middle. That means the image can never slip out of alignment. You always find the centre of the eyepiece because the adapter is centred automatically. Another advantage is that your mobile phone can be set up faster than with many other adapters.

Easy to use:

 1.  Adjust the clamp to fit the eyepiece of your scope, but don't tighten it onto the scope just yet. Gently slide it back off the eyepiece.
 2.  Tighten the eyepiece fixed knob securely and mount the phone on the adapter, then screw the knob into the end.
 3.  Flip it over and loosen the knob to adjust the arm. Rotate it or adjust it up or down until you get the camera of your phone centered into the circle where the eyepiece will be. Once it's centered, tighten the knob securely.
 4.  Turn on the camera and slide the clamp back onto the eyepiece. This allows you to make sure your field of view is clear. You'll have to make sure the black edges of the circle around your field of view are clear not blurry. When it's lined up right, tighten the clamp. This will keep your shots steady and clear.
