Double Stack Full Disk - 13th May

Adding a second etalon to the Lunt LS50 solar telescope through 'double stacking' has the effect of increasing contrast on the solar disk as a result of reduced continuum leakage in the wings of the Hydroge Alpha centreline.  It gives an alternative take on the single stack view.  Taken with the PGR Chameleon 3 camera.
