Description

The thermal nightside of Venus on October 7th, 5 UTC. Here the (darker) high altitude terrain of Aphrodite Terra is visible at right, near the terminator of the planet. The white blob is the severely overexposed dayside crescent. Diffraction spikes from the scope's spider vanes, and the camera matrix can be seen.

45 mins integrated using 45msec exposures at 300gain with the Uranus-C at 1800mm f/4.4.

Note areas of black ringing around the dayside appeared whilst sharpening. Here I've mapped those pixels to pure white. It looks a little more natural this way, and is analogous to the raw data.

WinJupos Simulation for the date can be seen below:
