This bright reflection nebula lies in the constellation of Cepheus the king.
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 Astronomic narrowband filters, H-alpha, SII and OIII. I capture 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 exposure time were 60 minues with a H-alpha filter, 40 minutes with a SII filter, 35 minutes with an OIII and aso 15 minutes using a blue filter.
