These days Bess observers were asked for Ha spectra coverage of HD171219 in Ophiucus by COROT team. COROT is a very accurate photometric space telescope. Its primary goal is asteroseismology, star variability and secondary is eclisping exolplanet (16...

This new highly variable Be star seems to be very strange. Each six differents spectrums taken between April 25th and June 6th are different ! So fast and intense variation from a Be star are not common. Sheliak is an example, perhaps unique with FF cam....

The LhiresIII spectrograph has a built-in neon lamp for calibrating stellar spectrum. Taking one neon spectra before and after stellar exposition is highly recommended in high resolution spectrography cause of the mechanical instability of this "at telescope...

Spectroscopy of eps aur in these times is a tought task. I've been able to follow esp aur during end of may and this early June with a higher pier. I've started capture during daylight, with manual autoguiding, having still 40mm before epsaur set behing...
