M31 - 8.11.2021 at 23.00 Järvenpää Observation number 102275

Visibility IV / V

Eemil Pietilä, Ursa (Etelä-Suomi)

I was lazy and couldn’t go out into the field to shoot, so I decided to photograph the Andromeda Galaxy from my backyard. Now that I was in my own backyard and got power with an extension cord, I also decided to use a laptop that rotates on my laptop for the first time. Personally, I was inside in the warmth when the camera snapped pictures outside.

I also stacked the Andromeda pictures I took in October, so the total exposure was 4 hours.

      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.
