Description

NGC6946 - aka The Fireworks Galaxy

Less than 45 minutes of light collected in about two hours because of fast passing clouds.

Clearly there were strong winds at a certain height above the ground, so transparency (when there were no clouds) was good but the seeing rather shoddy.

Nice job done by the AZ-GTi mount by tracking precisely for all that time, providing consistently valid (88% good frames) 30 seconds exposures at 680mm focal length.

The 0.5X focal reducer was used to achieve an effective focal ratio of about F7.5 .
