Description

Uploading to show what can be done is less than 1.5 hours with terrible light pollution (moon) and a fogging sensor. Unguided. Bicolor image.

Lots of challenges with this one, besides the glare from the moon it was a hot evening with high-level moisture scattering the moon-light. High humidity resulted in some fogging on the sensor window at -20, changed setpoint to -15 which improved but did not eliminate the problem.
