Simens 147, The Spaghetti Nebula.
This large patch of nebulosity lies in the constellation of Taurus the bull.
Taken using a 135 mm lens with a set of Astronomik filters attached in front, S11, HA, O111 and blue. The camera was an Atik 383L mono CCD camera piggybacked on a 10 inch reflector mounted on a Vixen Atlux mount. I captured 3 minute sub frames with matching dark frames and combined them with flat field frames to reduce the effect of noise and vignetting in the final image.
The total exposure time was 25 minutes using an S11 filter, 30 minutes using an O111 filter, 72 minutes using a H Alpha filter and 10 minutes using a blue filter.
