Last night, I try to do SS Cyg with eshel spectrograph, not very easy because of the weather (lot of clouds).

I've always wanted to catch this moment on a CV with the LHires for a long time, now it seems the right moment.

Sum of the 23 x 10 min, R~2380 (35um slit + 600/mm grating):

Processing here was tricky, "wavelength register" feature misbehaved, had to work it around (ref.star was processed only at final stage, with some extra manual work in IRAF needed).

Enjoy!
