Description:
A surprisingly excellent seeing calls for a high-magnification study. As Saturn is just below my horizon, I decide to pick a rather complicated structure: the irregular Cigar galaxy of the UMa constellation. Thanks to the 300x power, the FoV is coal black, the galaxy is so bright that it actually ruins my dark adaptation, faint stars sparkling at the edge of averted vision visibility. Too bad, that the galaxy itself is located on a rather light polluted part of my sky, but it still shows plenty of structures. During the observation, I had my second magneto-acoustic meteor experience in my life: this is the phenomenon when you actually hear a swishing or crackling sound at the same time the meteor flares in the atmosphere. The common part in both cases were that I was standing VERY close to a wire mesh fence, and a <0 mag meteor in the zenith, with a definite ionized tail.
