Main page on SN2011dh in NGC5194

Some initial spectra that need to be calibrated. These where done using the Star Analyser (100 lines/mm) mounted in the filter wheel of the 20 inch Telescope and Observatory

Images are stacked 11 x 20 sec exposures. Sky conditions were poor and the telescope was not able to guide that night and had a tracking problem, hence the short exposures. A number of strong absorption lines can be seen.

There are similarities to Torsten's image (but his is much better quaility!):- []
