Orions Belt & Sword - widefield 26.01.09.

Recommended Posts

Yet another Astrotrac test, this time with a Sigma tele zoom just to see if it works.

From a dozen frames mixed of 2 min isos 800 & 1600 inc a few 15sec short ones.

Sigma 55-200 zoom @ 78mm (cropped) @f4.5 on 400D

Had to use a dewband on the lens in the dewy/frosty conditions last night.
