Celestron Cometron Manual

Thank you for purchasing a Celestron Cometron binocular. We trust this binocular will provide you
with years of enjoyment and faithful service. Please read the instructions carefully before using your
binocular to ensure proper use and care.
The interpupillary distance, or the distance
between the pupils, varies from person to
person. The binocular must be correctly aligned
(adjusted) to the distance between your pupils
to achieve a single, clear image. To adjust this
distance, lift the binocular up to your eyes (using
both hands) and look through them at an object
in the distance. Move the two barrels (halves)
of the binocular closer together or further
apart until you see a single, clear image (Fig.
2). Check that the interpupillary distance is set
correctly every time you use your binocular.
