Hi,

After 2 weeks of abstinence :-) yesterday after arriving at the Observatory and
warming up everything I finally was able to so some spectroscopy again :-)

This little bugger of Comet is mowing quite fast, ~ 1' 38" per hour, so I had to
lock for the guiding on the comet itself, but at mag 8.0 and a lot of its light
taken away by the slit of the spectrograph I had to use 10 second of exposure
time and so I was ablt to guide on a small prt of the core itself but more on
the fuzzy part refelcted outside of the slit.

Spectrograph is LISA with 23µm slit on a AT 8" RC and the QSI520i CCD camera.

In order to know what to look for, I made a search in the WWW " spectrum of a
comet " and found this page

and by looking at this images
Hale-Bopp

Hyakutake

I knew I had nailed it and here is my result :-)

Comet C72009 P1 Garradd

Thanks for reading and looking :-)

regards Rainer
