M8 & M20

This image was taken on 35mm slide film using a 300mm telephoto lens. The lens was not an ED model, hence there is a considerable amount of chromatic aberration in evidence, particularly the blue halos around the brighter stars. There are techniques that can be used in post processing to supress the halos but they have not been applied here. The image is showing some nice colors and a good amount of nebulosity nonetheless. It has been cropped about 20% for better framing. _Imager: Olympus OM-1, Fuji Provia 400F 35mm slide film, scanned at 4,032 x 2,688 (10.8 MP). _Lens: Sun 300mm f/4.5 @ f/5.6. _Exposure: Single, 30 minutes. _Guider: Manually guided using 80mm f/5 guidescope. _Date: July 19, 2004. _Location: Dyer's Bay, Northern Bruce Peninsula.
