Thank you for your purchase of a Baader Planetarium TriBand Schmidt-Cassegrain. These
telescopes are made for professional observations of the Sun with large apertures (espe-
cially in combination with H-alpha-filters) and for narrowband astrophotography.
There are some special things to take in account when observing the Sun with such a
large aperture. For best results, we recommend that you spend a few minutes reading this
manual before using your new TriBand-SCT telescope.
