M1 - 21.1.2023 at 00.00 - 21.1.2023 at 01.00 Janakkala, Tervakoski Observation number 111499

Visibility III / V

Petri Kuossari, Riihimäen tähtit. yhdistys

The weather report promised maybe half an hour or at most one hour of clear skies in the evening, so the pipe line to cool down. I started around 19:00 and finally the evening stretched into the morning. There were bigger changes to the plans because I wasn't prepared for the observations of the whole night. Fortunately, the weather report can sometimes also be positive. The main target was the clear comet C/2022 E3, both scientific observations and pictures for your own pleasure. I also noticed a couple of transits of asteroids during the night. More about them after the analyzes are completed.

The last target of the night was the M1 crab fog. There was an ice fog in the sky, and the batteries in the tubes were low, so I ended the night here.

      Supernova remnant is the remnant of the big star died in supernova explosion. The supernova remnants are quite irregularly shaped. Rather many of them ring-like strusture.

      The moderate big instruments and possibly special filters are needed to see supernova remnants.

       

      The Crab Nebula was born in a star explosion in  1054. This is the easiest supernova remnant in the sky to observe. Image Tero Hirvikoski.
