M13 - 17.8.2020 at 00.15 Kangasala Observation number 92956

Visibility Unclassified

Markku Lintinen, Tampereen Ursa

Here is my first deep sky shooting exercise. I used a pre-assembled astroberry distro. Somewhat surprisingly, the ASTAP stacking software included in the package did not even agree to open the RGB24 TIFF format that was in the default settings of the imaging software, so my stacking intentions remained next time.

      Globular cluster is a ball-shaped group of thousand of stars. Typically it looks like a round fuzzy spot. With bigger instruments a part of the stars in the cluster can be seen as sepaterated.
