AR12662 in Ha with the Airylab HaT - 17th June

These 2 shots were both taken with the Airylab Hat, double stacked Quark, and PGR Chameleon 3 with 2x2 binning, the only difference being the wider field view used the Baader 0.7x solar telecompressor to give an effective focal length of just over 6 metres compared to the native focal length of nearly 9 metres using the quarks 4.3x telecentric instead of the Airlylab 2.7x telecentric.  The seeing wasn't perfect at this scale but it was good enough to get a couple of acceptable images.
