Hello,

Horsehead is a beautiful but difficult to image nebula because of the bright star Alnitak.

Imaged with the Moravian G3-16200 at my Takahashi FSQ 106.  L:R:G:B:HA=150:120:120:120:360 minutes. Subexposures were 10 minutes for LRGB and 30 minutes for HA.

Processing with PixInsight and Photoshop CS6.

Enjoy

Reinhold
