NGC1579. Commonly named the northern Trifid. This faint patch of nebulosity lies in the constellation of Perseus. I was using my ten inch f/4.8 reflector, a Vixen Atlux mount, 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. The total exposure times were 90 minutes using a H-alpha filter, 50 minutes using an O111 filter, 35 minutes using an S11 filter and 20 minutes using a blue filter.
