M31, M32 ja M110 - 20.8.2017 at 23.00 - 21.8.2017 at 03.00 Pori Observation number 66366

Visibility IV / V

Jarkko Suominen, Porin Karhunvartijat

Here’s my start to the season, as well as the official first exposure for my new tube. The surroundings of Andromeda have not come as described for a few years, so I thought now was the time for that.

The last time seems to be the first exposure on my Newton tube ... Which is probably four years away!

There was a lot of hurry to the observation site, which I already knew was a bit light-polluted (the forest near Pori airport) .. but suitably close to my home.

After getting the equipment in sight, clouds appeared on the scene that visually stayed above me for an hour. I was already giving up when the constellation Andromeda started to split behind the clouds. So I started shooting from the partly cloudy sky, towards the end the sky became clear, but the background of the darkness of the sky was already beginning to suffer from the morning.

      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.
