Dark Filament - 18th June

This filament looked particularly dark on sundays sun, and I was pleasantly surprised when I looked at the final image the subtle detail that had been recorded.  The seeing must have been behaving at that point!  Taken with the 100mm Tal100R, Double stacked Quark running at f43, and a Baader 0.7x solar telecompressor to bring the focal length back to a more usable 3 metres.  The camera was the PGR Chameleon 3 using 2x2 binning to get a shorter exposure and larger pixels more suited to the focal length.
