Equipment6" refractor with Daystar H-alpha filter and a Skynyx 2-2M camera.
DescriptionI tried to catch the refraction of light in Venus' atmosphere between third and fourth contact. Using progressivly longer exposure times I finally cought a glimpse of the effect at 0.4 seconds. At such a long exposure time our own atmosphere blurs the view quite a bit. The refracted light is visible for roughly 30 degrees across the north pole of the planet. Not quite like the view from the Hinode spacecraft - but still!
