During the second night of the Deep sky meeting 2013, I was observing visually with Marko Tuhkunen with the Astrofox -telescope. During the first couple of hours of the night, we were giving a star show for a group of visitors, who haven’t ever been observing with a telescope like this! During this star show, we observed for example Messier 57, Messier 51, NGC 7009 and planet Uranus. All the objects we watched were absolutely stunning and awesome when seen through a telescope of this size! The visitors were also happy to see the celestial objects with this unusually large instrument! After the visitors had left, we were doing some group observing with the participants. For example, we viewed galaxy NGC NGC 4319 & quasar Markarian 205 and also many other ‘eye-candy’ objects. NGC 4319 & Markarian 205 was the only object that I could properly observe and sketch.

NGC 4319 & Markarian 205

NGC 4319 is a spiral galaxy in the constellation of Draco, Markarian 205 is a quasar just 1′ south of the galaxy. The distance of the galaxy is about 70 million light years, whereas the quasar is much more further away, the distance of it is about 1 billion light years! NGC 4319 was visible as an oval-shaped nebula with bright, stellar core. The long axis of the galaxy is oriented in NW-SW -direction. The visual size of the galaxy is roughly 2´x1´. In the NW and SE edges of the galaxy, hints of the spiral structure can be seen. The quasar Markarian 205 was visible as a star-like object 1′ south of the core of NGC 4319. The brightness of the quasar is roughly 15 magnitudes.
