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

If possible, power is supplied via the separately available Baader OTP 60W: Outdoor

Telescope Power Supply 60W with protective-disconnect ellbowed plug

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.
