Venus UTC

CM1: 215.50°

CM2: 220.30°

CLat: -4.30°

Description

Much better night for imaging Venus with the C14 than the last session a month ago.

First light of my Thorlabs FELH1000. A filter like this blocks most light reflected off the thick sulfuric acid clouds on the day-side. The clouds also happen to be translucent at 1000nm, allowing the faint infrared light emitted by the surface to be seen on the night-side.

I couldn't have done this without some research and asking around. Here are resources I found useful:
Image the surface of Venus this winter!
