Troubleshooting
The image on my screen is not centered.
Likely Cause: This is most likely caused by the camera not being centered on the adapter or the adapter
is not fully seated on the EYEPIECE.
Fix: Check that phone is flat on the adapter, check that adapter is fully seated on EYEPIECE, check that
camera lens is centered in APERTURE.
I tightened the COLLAR down with the 39mm-44mm COMPRESSION RING
installed and it still was too large to firmly grasp my EYEPIECE.
Likely Cause: The EYEPIECE is less than 39mm in diameter.
Fix: Order the SMALL EYEPIECE ACCESSORY kit which accommodates EYEPIECES from 23mm to 40mm.
I don’t get a full image just a small circle
Likely Cause: This is due to “VIGNETTING” which is due to the image coming through and not fully
covering the camera sensor. Several things can contribute to how much VIGNETTING occurs including
the design of the EYEPIECE itself (exit pupil diameter and focal plane distance), the size and position of
the camera sensor element in the phone, the thickness of any protective case and how much optical
zoom is selected.
Fixes: Make sure adapter is seated on EYEPIECE and the eyecup is fully retracted unless needed for
engagement. The standard method to eliminate is to simply use a slight amount of digital zoom on the
phone camera. Note that a thinner protective case will incrementally reduce any VIGNETTING.
