M31 - 10.3.2023 at 19.08 - 10.3.2023 at 19.30 Janakkala, Tervakoski Observation number 113289

Visibility III / V

Petri Kuossari, Riihimäen tähtit. yhdistys

I wouldn't have put this picture here otherwise, but for people who are interested in the DWARF II tube. This photo was taken with a tube weighing only 1.2 kilograms. And this pipe is not expensive. Maybe this works better for nature photography, can track flying birds automatically, can also take video or even a billion pixel landscape photo. The software still seems to be Unfinished.

      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.
