M67 - Total Exposure 164s (82 x 2s)
Best 82 frames from 200
Stacked and Displayed in CCDSoft

(
Frames selected using CCD Inspector & Stacked in CCDSoft. DeepSkyStacker unable to recognise sufficient stars for alignment prior to stacking)
Stars are sharper in this 'Lucky Seeing' image than in the
90s (3x30s) traditional CCD image above, but is much more
affected by poor flat fielding and/or affected by dew build-up
on the front corrector lens.
