Selztal Observatory goes spectroscopy
Selztal Observatory goes spectroscopy.
During the last year I started to collect some experience in spectroscopic observations.
This new "window" is less sensitive to generell light polution is more challanging on technical aspects of observation. Beside mechanical issues it's important to take care that the maximum of light passes the slit of the spectrograph, but giuding errors does not destroy the image and have influence on the overall amount of light passing the slit.
