This transit of the HST (Hubble Space Telescope) was taken from Queensland, Australia, simultaneously with the 2012 transit of Venus on June 6th, at 01:42:25 UTC. Thanks to the continuous shooting mode of the Nikon D4 DSLR running at 10 fps, 9 images of the HST were recorded during its 0.9s transit (1/8000s, 100 iso, raw mode). Turbulence was moderate to high.

HST distance to observer: 750 km. Speed: 7.5 km/s. HST maximum size: 13m. Instrument: Takahashi FSQ-106ED refractor on EM-11 mount with Baader Herschel prism and FFC amplifier. Transit forecast (place, time) calculated with

More images to come (under processing), including: the ring of the atmosphere of Venus around the first contact, images of the transit in H-alpha, the full ring of Venus 24 hours after the transit at 1.8 of the Sun



(only one FSQ is mine, the other and its mount come from Optique Unterliden, Colmar)
