Animations With The HaT - 17th April
Taken with the Airlylab HaT at 203mm aperture, 4.2m focal length achieved with the Baader solar telecompressor with a PST etalon double stacked with a Daystar Quark, I did 2x2 binning of the PGR Grasshopper 3 which with it's then pseudo 6.9um pixels gives a perfect sampling rate for this set up. It also gives blisteringly fast exposure time of just 3ms which has the effect of freezing the seeing in some pretty dire conditions. Other added bonus of this is that the frame rate of the camera is increased and time for stacking is also reduced. An interesting setup to try again...
