Description

Narrow band image of the Rosette Nebula, with data acquired over two days. This was taken in my light-polluted back yard (borderline white zone) using a 135 mm telephoto lens sitting on top of my C8 telescope. The image is a composite of H-alpha and O-iii data. The nebula is rather low in the sky in mid-April, I had to catch it in early evening. The lens was stopped down to f/2.8 for this image.

Camera parameters:

Gain = 170

Offset = 20

60 second exposures (40x for each filter.)

I slightly shifted the B and G channels in an attempt to replicate the true color of the nebula.
