3. Take the 1.25” eyepiece and if necessary remove the rubber eyecup by pulling it straight
off the eyepiece body.
4. Loosen the set screws located on the eyepiece holder on the inside of the adapter. Place
the black portion of the eyepiece into the eyepiece holder and tighten the screws to
secure the eyepiece in place.
5. Now take the adapter with the phone and eyepiece attached and insert the chrome
barrel of the eyepiece into the diagonal on the back of the telescope’s focuser. Secure it
in place by tightening the set screws on the diagonal.
6. Activate your camera app on your smartphone and adjust the focus, just as you would
the eyepiece, this time using the image that appears on your screen.
NOTE: Make sure you turn the phone’s flash off.
7. When the image appears sharp snap your image. It is best to try this in the daytime first,
then, once everything is setup correctly, take it outside and try shooting the Moon. Once
you have practiced and are comfortable using the low power eyepieces, try using the
camera adapter with a more powerful eyepiece for higher magnification.
