Description

When I was a teenager (a long time ago:)) and got my first telescope, I wanted to take a colourful photo of the nebulas in orion, especially of the Horsehead nebula. This week end I achieved the goal with the RASA 8 astrograph. Fore once the sky was clear for two nights and Orion showed up in the east late night. Orion is abouth the southernmost I can reach from my backyard observatory. Enjoy...
