Thanks Olivier, I'll check the link

Nice, I am doing Mizar spectra too, at R=4000. I am able to see how h-alpha line becomes double. I plan to share my results soon.

¿How did you get that 2d espectral sequence?

Miguel

Spectrum from two hours observation.

Here is my last spectrum from tonight.
Unfortunately I don't have enough time span to monitor profile changes through the night.

Spectrum from last night. Double peak. L-200 spectrograph with 600l/mm grating. R=4351 computed by ISIS.

Hi Keith, thanks very much. I didn't supposed you referred to instrumental response, I thought you were talking about Infrared :oops: :lol: Yes, I do instr. response curves. I usually do one for every object I make an spectrum. Alpy seems to be very stable, and the obtained response curves are very ...
