The Tadpole Nebula

IC410 . The Tadpole nebula.This emission nebula lies in the constellation of Auriga at a distance of about 10,000 light years. I took this image under clear moonless sky conditions using my ten inch f/4.8 reflector an Atik 383L mono CCD camera and PHD auto guiding. 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. The total exposure times was sixty minutes using a H-Alpha filter, sixty minutes using an OIII filter, sixty minutes using an SII filter and twenty minutes using a blue filter.
