Deep space - 13.9.2021 at 21.45 Parikkala Observation number 101242

Visibility Unclassified

Eeva-Kaisa Ahlamo, Turun Ursa

Well, it so happened that when Andromeda was screened long enough, it turned on the afterburners and started pulling. A nice cloud of smoke, but what more would you expect from a galaxy of that size. My best flying saucer observation to date.

Aka Windy night, but the yard was so calm that the telescope did not swing.

      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.

Tuohan motivoi yrittämään itsekin. Kierteisrakennettakin näkyvissä. Ja vain yksittäisvalotus!
