M81, M82 - 28.2.2016 at 00.30 Kauhava Observation number 49308

Visibility II / V

Oskari Syynimaa, Lakeuden Ursa

The sky cleared for a couple of hours, so I made the hasty decision to try to get a picture of the M81 and M82 galaxies. However, I failed terribly, because there were many more in the picture ...;) At first the sky looked really clear, but I should have guessed that it was immediately fogging when the temperature started to drop. However, the targets were somewhat in zenith, so the fog didn’t bother me that much. The fog soon fell, but then the moon rose to disturb. Even a thin cloud board actually wandered over the entire shooting session, so the weather was by no means good for anything. Surprisingly, there were about many of those dimmer galaxies visible. :)

    • Spiral galaxy info

      Spiral galaxy is a stellar system where there are outwards arched spiral arms from roundish (spiral galaxies) or bar-shaped (barred spiral galaxies) central condensation.

      The apparent shape of spiral galaxied depends on out observation direction. From above they are quite round. From the side they lens-shaped with a bulge in the middle.

      Generally a rather large instrument, good weather conditions and observational expereince are needed to see spiral arms. Usually spiral galaxies look like a fuzzy spots.
