M1 LUM/Ha/color picture taken Jan-2017. Exposure LUM: 134*30sec, Ha: 26*5min. and color: 57*4min.
Observatorie construction during 2005

Welcome to my astro homepage, which have one purpose only, to show and share with you my best astro pictures taken from Copenhagen, Denmark.
Kind regards Niels V. Christensen

The obs. picture shown at the right side is from 2005.  A afternoon in 2005 with very special weather conditions when the sun disappeared below the horizon. The observatory at that time was not finalized and among other things the rotating roof was not yet made and mounted.
