Description

This is a mosaic of the nebulosity surrounding the constellation of Cygnus taken through H-alpha, SII and OII filters with the data combined using the Hubble palette.   It was taken at 2 different focal lengths.  At the center is a 53 image mosaic taken with a Takahashi FSQ106 and an SBIG STXL-11002.  This is embedded in a 6 image mosaic taken with a Rokinon 135mm lens and an ASI6200MM Pro.  This means the overall image resolution is 5.7 arcsecs/pixel which is a high resolution for such a wide field.  You can see a higher resolution image at the link above.
