Description

My first reasonable image of Venus, just before sunrise on September 10, 2023. 

I really had to work on the ADC to reduce the chromatic dispersion, but I'm happy with the result! 

1 minute of 480p video at 155 FPS (gain 183, 1 ms exposure), 3x drizzle integration and light wavelet sharpening.

Effective focal length:
* Apparent diameter on Sep 10: 43.40" 
* Pixel diameter after 3x drizzle: 980px
* Raw pixel diameter: 327px
* Sensor pixel size: 2.9 micron
* Size on sensor: 948 micron ~ 0.95 mm
* Effective focal length: (206265 * 0.948) / 44.3 ~ 4415 mm
