Hallo Dadosbenutzer,
einer meiner Schüler möchte in seiner Seminararbeit das Doppelsternsystem Mizar A untersuchen. Die Ausstattung unserer Schulsternwarte: C8 + DADOS + DSLR Canon EOS 60da + STV zum Nachführen auf einer Alt-Montierung. Hab ich eine Chance die Aufspaltung der Spektrallinien zu sehen?
Für Tipps wäre ich sehr dankbar!
Beste Grüße Roland

HI Roland,

Sorry to answer in English but my German is not very good :(

I do not know the resolution of the spectrograph DADOS but I experimented with a spectro eshel (resolution of R = 11000) and here is what I could obtain.

Hallo Roland, in unserem Fachgruppenjournal SPEKTRUM hatte Lothar Schanne das schon spaltlos gemacht. http://spektroskopie.fg-vds.de/pdf/Spektrum38.pdf

Hallo Thomas und Oliver,
vielen Dank für die Hinweise. Es scheint also zu gehen. Dann probieren wir's mal.
Beste Grüße Roland
