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.

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.
