During this session, I was doing some deep sky- observing in Friitala, Ulvila. This site is located close to towns of Pori and Ulvila, and it means that the light pollution domes of these urban areas are destroying northern and eastern sky. The background sky is not really dark, but dark enough for doing some deep sky observing. This time I observed and sketched Messier 76, a planetary nebula in constellation of Perseus and globular cluster Messier 92 in constellation of Hercules. Although the sky was clear and conditions were ok, I had to go sleeping early because I had been awake for long time already.
Messier 76: @133x, this planetary nebula was visible as a small, SW-NE oriented, fuzzy and greatly elongated nebula. The nebula is also known as the little dumpell nebula, and the characteristic wings of the nebula were also visible. The southwesternmost one of them was brighter than the opposite one. The wings are best visible with averted vision. The nebula is pretty small and dim, but it is in easy place and thus it is easy to find. This object is nice and interesting object to observe visually, also for smaller instruments.
Messier 92: @67x, bright globular cluster, which was easily resolved almost into the core! The brightness, and hence the density of stars of the cluster increases clearly towards the core. The core is dense and much brighter than the outer parts of the cluster. This is visually very impressive object, also for small instruments.
