Crux at Zenith

[avandonk]

While waiting for Antares to get higher and the cloud to come in last night, took a set of data of Crux at the zenith.

Details.
Canon 5DH, Canon 300mm F2.8L at f/3.5. Hutech LPR filter. Fridge at -11.0C.
Exposures 20 x(15s, 30s, 60s & 120s) at 1600 ISO. Usual HDR method.

Seeing and transparency both very good. Ambient was about 2C.

Very nicely framed, Bert - lots of stars :). I see a hint of a green-blue cast on the large jpeg.
