2. Adjusting Focus
To focus your EclipSmart binocular, simply turn the large dial
located between the two barrels until you see a sharp image
of the solar disk.
3. Adjusting Diopter
As solar observation with binoculars does not require the level
of fine detail that other types of astronomical or terrestrial
observation does, most users will not need to make any
adjustments to the diopter compensation of the binocular
other than setting it to the zero ("0") mark. However, if you would like to fine tune the
diopter for your unique eyesight, follow these steps, making sure that you never allow
yourself to look at the Sun without both eyepieces of the binocular fully in front of
your eyes at all times. Begin with the EclipSmart binocular safely positioned in front
of your eyes and the solar disk in view, without moving the binocular away from your
eyes:
A. Keep both eyes open and use one hand to cover the right objective lens. Adjust
the center focus dial until the image you see through the left eyepiece is sharp.
Do not touch the center focus dial again until this process is complete.
