OHP 2011 - Spectroscopy Workshop
night 3 (from 02-08 to 03-08)
Due to technical problems with the LHIRES spectrometer, I switched to the digital camera.
This night I did spectroscopy by discussing with other observers.
Acquisition
Instrument = Vixen VISAC VC200L with focal reducer (D=200mm, F/D=6.4)
Camera = Canon EOS 450D, filter not removed
Software = EOS utility
Processing
Software = IRIS v5.58
The comet was in Pegasus, position close to alpha=21:29:50, delta=+12:55:20 with mag=8.8 (MPC).
One single exposure of 3 min.
8 exposures of 3 min. The red parts are rather weak, due to the IR cutting filter that has not been removed from the camera.
8 exposures of 3 min.
