IC 342 - 10.12.2020 at 19.01 - 11.12.2020 at 00.15 Järvenpää Observation number 95166

Visibility III / V

Ari Jokinen, Etelä-Suomen kosmol. seura

I photographed Giraffe’s fine helical galaxy IC 342 (UGC 2847). Exposure for about 10 hours. It is quite dim and is called #The Hidden Galaksy. ”The reason is its location near the equator of our galaxy with a lot of interstellar material.

Another image treated a little more harshly and H-alpha added to the R channel

      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.

Hyvä ja kannatettava idea toisen kuvan revitelty versio, tälläistä kaipaa  useasti siisteistäkin kuvista. Kuvien merkitys laajenee !
