Diffuse nebula in Orion
This image was obtained by using a focal reducer on my 12-inch Meade telescope, which gave an effective focal ratio of f/5.4 with my camera. The purpose of the focal reducer is to give a larger field of view than would be obtained without it, and this field is just about the right size to capture the whole nebula. The largest section of the nebula is Messier 42, and the smaller, teardrop-shaped section above it is Messier 43.
