Western Proms With A Double Stacked Quark - 4th October

When properly tuned there are no hot spotting or sweet spotting issues with the double stacked Quark as this 2 pane mosaic shows.  The double limb feature is now gone ad filaments take on a real 3D appearance as they near the limb.  I wish I could have taken this photo about 6 hours early as it would really maximise the effect.  Taken with the 70mm at f6 with a 0.5x reducer and a DMK31 camera.
