Description

This time the air was not as turbulent as during First Light, but still quite unfavorable. Anyway, I dared to use a 2x barlow to increase the FL to about 4000mm. The result is sobering but if taken in calm air I'd probably would lift off my socks (those summer socks with the holes). Exposed 14ms at gain 250, no drizzle.

The images in the revision are stacks of 500 frames taken at FL 2000mm through an IR640nm filter at gain 200, mono-8, 10-bit ADC, 1.5x drizzled.

Have a great cloud-free weekend!
