Scope of delivery
The scope of delivery of the SolarSpectrum filters con-
sists of the actual H-alpha filter, the control unit and the
pre-installed 2" or T-2 (M42x0.75) adapters listed above.
The control boxes are made individually to fit the filter
and may vary in appearance.
In addition, the following parts are absolutely necessary:
• A telecentric system to operate the filter at apprimately
f/30 and to achieve a parallel beam of light, which is
necessary for the H-alpha-filter to work properly. For
filters with an FHWM narrower than 0.5Å, an even
slower f/ratio is recommended.
• An energy reflecting filter to save the filter system
from the solar heat.
• A power supply
Power Supply
If possible, power is supplied via the separately available Baader OTP 60W: Outdoor
Telescope Power Supply 60W with protective-disconnect ellbowed plug
# 2457630
. It
supplies 12.8V at 5 A.
If no power outlet is available, the filter can be operated with an optional battery pack
for mobile use. The Celestron Power-Tank LiFePO

works fine. Remember that the cable must be tip positive.
Tipp experienced DIY-constructors:
A sufficiently strong power supply can power
both mount and filter through a Y-cable, which keeps your cable management clean
and easy.
Please note:
Do not reverse the polarity of the power supply. If possible, use the po-
wer supply unit supplied or cables with reverse polarity protection. Damage caused by
reversed polarity is not covered by the warranty.
