Description

In this composition I wanted to float the nebula off to the side but clearly in a sea of colorful stars. I chose Ha to enhance the HII elements and make the nebula bright, and RGB to get natural coloration as opposed to SHO. There are open clusters to the left [in image] of the Rosette...NGC 2252, Cr 104, Cr 107, Cr 106 [up high], and Cr 97 [above the nebula].

Description: I increased the saturation a little in this version as it looked a bit washed out after I uploaded it.
