 Despite the high wind all day long, and poor seeing at night this image with the shorter focal length retains excellent sharpness and color detail because it simply cannot resolve the bad seeing. This is a great advantage on many nights here on the Mogollon Rim , and allows imaging on evenings which would other wise be fruitless with the larger instrument. This image is the very first guided image with the new Stellarvue, and stars appear sharp right to the edge.

The colors of the nebula recorded by the 10d are blue biased because of the standard IR blocking filter inside the camera. However, we can partially compensate for this in Photoshop by balancing the hue of the magentas to include more red.

Processing: Seven layers of different exposures were combined in Photoshop using layer masks and the eraser tool. The final image was set in the proper saturation with the amazing saturation curves tool in Pix Insight.
