It’s been a while since our last image as we’re both busy trying to get Star Vistas camera-ready for our publishers by 1st April 2008.  However, Noel & I managed to free up some time to get this latest image to you, the massive emission nebula IC1396, containing the famous “elephant’s trunk” – in the constellation Cepheus:

This has a total exposure time of just over 19 hours using both RGB and H-alpha data, collected with the usual Sky 90/M25C combination.  The five datasets used in constructing this image are as follows:

  • 16 x 20 minutes, Ha filter
  • 10 x 20 minutes, Ha filter
  • 9 x 20 minutes, Ha filter
  • 29 x 7.5 minutes, IDAS filter
  • 30 x 7.5 minutes, IDAS filter

Noel put in a massive 16 hours processing time on this one!  Enjoy!!
