IC 5146 lies in the constellation of Cygnus the Swan. I took this image using my 80mm, f/6.3 refractor, a Vixen Atlux mount, PHD auto-guiding, an Atik 383L mono CCD camera and a set of Astronomik narrowband filters SII, OIII and H-alpha.
I captured five minute sub frames with matching dark frames and combined them with flat fields to reduce the effect of vignetting in the final image.
The total exxposure times were 60 minutes using SII and OIII filters and 90 minutes using a H-alpha filter.
