Image Description:
- This is M78, a reflection nebula n the constellation of Orion. This was shot over two really horrible nights, with awful transparency and a bunch of high clouds. This object requires tons of exposure on pristine nights to do it justice. The colors do look pretty cool though, even in this modest attempt. A higher resolution image is also available. North is up.
