This was absolutely on the limits of what I could image and the first time I have ever captured so much of the horns of Venus.  I waited for the Sun to dip behind my house and then had about 15 minutes in which to find and image Venus in bright sunlight before I lost it too behind my house.  Venus was now less than half a percent lit (0.04 proportion lit according to Cartes Du Ciel)  and the thinnest I've seen. Visually on screen it almost looked like a complete circle at times.

This is my best single stack from several videos at 312 fps, this one is the best 25% of around 9,000 subframes.
