The H-Alpha-Sun - Baader Planetarium HERSCHEL PRISM MARK II Instruction Manual

Finally, a note: Observing the prominences at the solar limb is not possible with a
Herschel prism – not even in combination with an H-alpha filter for deep-sky observati-
on. On the one hand, the Herschel prism also attenuates the H-alpha line, on the other
hand, even very narrow-band deep-sky H-alpha filters with 3.5 nm are much wider-
band than the special H-alpha filters with around 0.06 nm passband.
At www.baader-planetarium.com/en/solar-observation/solar-spectrum-h-alpha-filters.html
you will find a selection of H-alpha filters for safe solar observation.
And now we wish you a lot of fun observing the sun in white light with the Safety Her-
schel prism.
