After a wonderful night in Parainen, I went again for observing in Parainen during the following night! During this observing session, observing conditions were nearly as good as they were last night. Only problem during this night was condensation of moisture to all optical surfaces. Otherwise conditions were good: sky was clear, and it was nearly calm all the time. Sky was dark and Moon was absent!

I started this night by observing zodiacal light, which was well visible in the NW sky. Observing zodiacal light is a popular pursuit nowadays in Finland, because now everyone know what to expect and how to observe this phenomena! So now we know for sure, that zodiacal light can be observed at latitude 62, or even higher! My observing site is located little bit north of latitude 60.

After observing zodiacal light, I went on observing some further-away targets, meaning variable stars and deep sky! First, I tried to observe Leo I, a dwarf galaxy in Leo, near Regulus. I gazed at the right spot, I sweeped around it and tried to catch it with averted vision. Nevertheless, this time I have to make a negative observation of this target. I just couldn’t see it. Sometimes I could see glimpses of something, but I’m not sure that I really saw the dwarf galaxy. I also tried to observe NGC 3115 in Crater, but I decided to give up on it because it was just at too low altitude.

After two not so lucky observing attempt, I decided to observe something I could surely be able to catch! I observed an interacting pair of galaxies, NGC 4567-8 in constellation of Virgo. This pair of galaxies is easy to find, it is located very close to Messier 58 and 59. The galaxies appeared as small, fuzzy elongated patches. This pair of galaxies were connected at their northern edges. The opening angle of the galaxies was about 60 degrees southwards. It was quite easy to separate the galaxies visually. The apparent visual diamater of the galaxy system is about 5′. This one is a really interesting target!

After this pair of galaxies, I aimed my telescope towards constellation of Hercules. In the northern part of this constellation, lies a small globular cluster, NGC 6229. For some reason, I had never observed this target before! At my ocular, this object appeared as a small, round, fuzzy spot. The cluster was not resolved. There isn’t much to see of this object with instrument of this size.

After doing some wandering in the realms of deep space, I returned to our own Milky way to do some variable star observations. I observed dwarf nova SS Cyg also this night, and it’s brightness seemed to be same than last night, 8,6 magnitudes. I observed also R Tri, R Cas and T Cas. All of these stars are now close to their minimum brightness, and it would have been impossible for me to observe these stars with my small refractor. R Cyg was so faint, that it wasn’t visible at all with my instrument!

After observing these stars, I decided to go home and get some sleep. I think I just had one of my best observing experiences during this season! Observing conditions were only inch away from being perfect and I could observe many interesting targets! I could also enjoy the wonderful atmosphere of nights of early spring here in Southwestern Finland!

Now it’s April and nights are getting quickly shorter, and phase of the Moon is also getting bigger. It means, that is observing season is soon over. But there are still some observing opportunities in late April and early May!
