Compare this to previous Bubble Nebula, imaged on a night of intermittent
clouds. Conditions were bettter for this image, which has better contrast,
more detail, smaller stars (maybe due to better focusing).
Guided at sub 1 pixel with SBIG STV. 13nm HA, 150min total (6-min subs) using
AP 130 @ F/4.5, Tak EM-200.
