    It's bad weather outside. So I decided for revision time. Watching on hubble heritage page today, I got the idea to try this one today....

    I am often asked, how I managed the great resolution of the inner globular parts in the bubble. The answer is quite easy. Because of it's brightness I shoot some three second subs with higher gain I always use with my ASI 1600. Obviously I freezed the seeing with this....
