Continuing my imaging of Venus during the 2019-2020 evening apparition. These images were captured on the night of March 26, 2020. Venus was 50% illuminated in this image. It has been a rough few weeks for astrophotography around here with clouds nearly every night. I had a brief window on the 26th around sunset and grabbed a series of quick captures under poor seeing and transparancy. Not my best Venus, but I was excited to capture an image at 50% illumination. Looking forward to seeing the crescent phase of Venus in the coming weeks (assuming the skies cooperate).

Imaged with a C8 Evo, ZWO ADC, Baader UV-IR Cut filters, and ZWO ASI224MC. Imaging train was configured to give me ~F/20. Image capture using Firecapture (see below for exposure settings). Stacking in AutoStakkert3 (best 5% of ~27000 frames captured over 180 seconds). Color balancing and Wavelet sharpening in Registax6. Derotated and combined images in WinJUPOS.

Exposure settings:
