IC 405

IC 405. This object is commonly named the Flaming star nebula, SH2-229. It lies in the constellation of Auriga at a distance of about 1,500 light years. I took this image on a clear moonless night under heavy light polluted sky conditions. I was using my ten inch F4.8 reflector, PHD auto guiding and an Atik 383L mono CCD camera. I captured five minute sub frames with matching dark frames and combined them with flat field frames to reduce the effect of vignetting in the
final image. Some of the colour data is a combination of narrowband data and RGB colour data using S11 for red HA for green and O111 for blue. The total exposure times was 60 minutes for H Alpha, 30 minutes for S11 and 30 minutes for O111 filter. However the total exposure times for the RGB colour data was 20 minutes for each filter.
