CARE AND CLEANING OF THE FILTER

Avoid touching the optical surfaces of the ﬁlter. Handle the ﬁlter by its cell only.

Keep the ﬁlter stored in its plastic case when not in use. If the ﬁlter remains

installed on the astrograph, keep the astrograph’s dust cover on.

Dust should normally be removed with a blower bulb or an optical cleaning

brush. If the ﬁlter must be cleaned, use optical grade tissue with a few drops of

optical cleaning solution applied to the tissue. Gently wipe one small area at a

time. Do not rub. Use a new tissue and solution for each wipe.
