Orion in Spring

Posted in Astrophotography with tags , , , , , , , , on 2009/04/28 by computerphysicslab

Orion constellation may be difficult to sight in Spring due to its low altitude near the bright west horizon at dusk. Nevertheless I took one subframe of 8 seconds of exposition under ISO-400 applying my new Canon EOS 450d plus 18-55mm lens.

With Paint Shop Pro I subtracted the background gradient due to dusk light. There is visible a pine branch below.
