Appendix B: Care of the
Optical components
If you always use dust caps after working with the DADOS, no
cleaning will be necessary.
Dust can only be cleaned from the grating and slit by Baader-
Planetarium. Do not clean gratings or slit yourself as this may
void the warranty.
Lenses cannot be cleaned with common cleaning agents.
Use only Baader Planetarium Optical Wonder fluid
(#2905007) to clean the lenses.
