Réalisation d'un spectro à fente basse résolution avec le SA 100 et le Canon EOS 50 D Bonjour à tous Afin d' améliorer la réponse dans le rouge du Canon...
Bonjour Pierre, (Anglais d'abord puis français par Google) The Star Analyser will work with a standard 350D up to about 7000A. To measure wavelengths longer...

Robin - while searching your reference a belated congrats on WR colour spectra via your Canon 350D DSLR + Staranalyser from last year - spectacular;-) Nytecam ...
Thanks Nytecam, WR star spectra certainly are pretty in colour and the SA works nicely with an unmodified 350D up to the H alpha wavelength at least. Cheers ...

hello, i send an image of spc RR Lyra of 18092008 can you help me with the identification of the lines? the blue spc is corrected with the sensitivity flat of...
Hello Dominique, This looks strange. The agreement between you spectrum and the library spectrum does not look very good. Can you put the images used to...

hello Robin, Wolfgang thanks for the comments, sorry for the late respons i send 4 images spc of altair as reference star: dispersion 15.95 Ä/px spc of RR...
Hello Dominique, It is surprising that your ATIK 2HS results were so poor. My home built version of the 2HS and a 200mm aperture worked very well. I was able...
At mag 14, this supernova should just be within range of a Star Analyser and an 8 inch scope or bigger from reasonably dark skies. (It is too far south for me)...
good evening, i used the spc of altair, taken with the Watec, and the prototype of the spc out the library of Vspec with division i found the data for the...
Hello h-g, Good to see the old quickcam is still working and producing good spectra :-) I have used visual spec and wavelength calibrated your spectrum using H...
Maybe a Sally question but.. Planning to take spectra in Ha of epsilon Aurigae in winter and next year. Question: The Ha filter, where to put it before or...
In my humble experience, doesn't matter. When placed infront, the grating will still diffract the light as normal, but obviously there's only the Ha available....
Hi h-g, Why use a filter? Eps Aurigae is very bright so you should not have a problem with sky background even with a slitless setup. The resolution of a ...
Hi Daniela, Ha is Hydrogen Alpha. The first line in the Balmer series at 6563 Angstrom. Many stars (including the sun) show this as an absorption line. Other...
Let me jump in here a bit. I'm sure Robin will have some say too. One of the most interesting areas of the spectrum of epsilon Aurigae (and many other stars)...
