AR 2645 taken through a 15cm refractor stopped down to 11.5 cm giving a focal ratio of F10.4.  A 1.5x Antares Barlow was placed ahead of the DayStar Combo Quark to give a final focal ratio of F25 (due to the geometry of the optics).  Attached to front of the Barlow is a UV/IR energy rejection filter.  Processing was completed using AS2! , RegiStax and GIMP 2.6.
