Double Stacked Disk 22nd July

Despite only being taken with 50mm aperture compared to the previous full disk which was taken at 90mm aperture, the higher contrast of the double stack setup makes details easier to see.  The filament and active region really stand out in comparison to the single stack image, with proms also being nice and easy too.  Taken with a Lunt50 etalon double stacked with a Daystar Quark on the 60mm f6 refractor,  a 0.7x Baader solar telecompressor was used to reduce the image scale so that the full disk would fit on the chip of the FLIR GH3 ICX916M camera.
