Description

The Rosette Nebula is a beautiful emission nebula in Monoceros.

This was captured with my new Hyperstar system on my C8. I am still trying to get the collimation better. The stars are very oblong! It is really a challenge to collimate. The seeing has been really poor also. 3/10 seeing. I wonder if that is another factor for the poor results.
