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!!
