DayStar Telescopes and filters
are all HAND MADE.
• Each instrument is hand
manufactured and assem-
bled one-by-one. Each is
unique. Slight variations in
construction that do not
affect performance may
occur.
• Each instrument is indivudually tested on the Sun. Sun testing is an
absolute necessity to assure quality performance. While every precaution is
taken to maintain the ‘like new’ appearance of the telescope, it may
encounter minor cosmetic smudges or abrasions on the mounting foot or
the drawtube during testing.
• The optical filter stack is assembled by human hands using special optical
couplant that must remain loose for over 10 years. Occasionally, if dis-
turbed, this couplant can migrate to optical surfaces. Do not disturb your
optical stack. If a small amount of couplant is smudged onto your outer
surfaces, it is best not to disturb it. It will not affect performance, like a large
mirror. Larger smears will need to be cleaned by technicians at our factory.
Solar Minimum Notice:
Let us remember that the Sun
has a sunspot minimum and
maximum cycle of about 11
years. We are currently
experiencing a period of
sunspot minmum that has
lasted surprisingly long. This
means that the sun may not
have as many exciting things
going on the day that you
view or image, than you may
have seen in photos or in the
past, if during a point of high-
er activity in the past.
This difference in visible activi-
ty is unrelated to the instru-
ment through which the sun is
viewed.
Prominences and active
regions will return as they
always have before.
