Moonn southreunaa

15.3.2022 at 19.12 - Helsinki, Kaivopuisto (V)
Paula Wirtanen, Ursa (Helsinki)

The moon was a little too sharp at dusk on Tuesday, the southbound was good. Peeking from the edge of the moon e.g. a crater named after the Belgian Jesuit astronomer Charles Malapert, who lived from 1581 to 1630. Malapert is hard to spot, but in ITV's 70s science series, Space Station Alfa was located in the Malapert Crater. Another nice glimpse was Amudsen named after Roald Amudsen . Bailly was just coming out of the terminator, creating handsome shadows. Figure 2 shows the entire Moon.

Clavius and Moonn southreunaa

14.3.2022 at 20.10 - 20.30 - Helsinki, Kaivopuisto (V)
Paula Wirtanen, Ursa (Helsinki)

The moon was really great at the Kaivopuisto observatory above the sea. This time the shooting trip was more successful than the last one, with the help of the Celestron 11 tower. Liberation was very good in a southerly direction, about five degrees. In the photo, nomenclature has been added to some of the craters. Processing the image made the rays of Tycho passing over Clavius stand out. Visually, they were more difficult to distinguish, however, by darkening the image and highlighting a few shadows, they are clearly visible. Also, a lot more detail was separated from the Schiller crater tha...

Moonn southeastisreunaa

18.2.2022 at 23.21 - Vantaa, Pähkinärinne
Paula Wirtanen, Ursa (Helsinki)

The southeastern edge of the moon is very cratered, as anyone who has looked at the moon can recognize. There was quite a good libration just south, but decent shadows to outline the various objects were actually on the southeast edge near the terminator. Tycho and Janssen stood out easily, Clavius' chair was outlined by darkening the image and a little wondering. The craters on that terminator caused a headache, but an experienced lunar observer, J Ari Kuula , helped identify them. Once Hommel was outlined, he was identified as Demonax and Boussingault. These craters are marked in the pic...

Julius Caesar, Albategnius

29.8.2021 at 00.51 - 01.10 - Vantaa, Pähkinärinne (IV)
Paula Wirtanen, Ursa (Helsinki)

Surprisingly clear! Or well, at least almost. However, the moon was invitingly rising, so yes it was a telescope to be fetched for use. I still got it used in August. First we had to look at what belongs to Jupiter. Seeing was surprisingly good and lasted even large magnifications without ripple. This was due to a thin overhead cloud, of course, meaning the details didn’t stand out significantly while the image remained a little soft, so I didn’t actually make an observation of the subject. 150x magnification was most useful, as with the Moon. However, the observation eye is worth the school a...

Moon

26.7.2021 at 01.28 - Vantaa, Pähkinärinne (IV)
Paula Wirtanen, Ursa (Helsinki)

The low Moon looked great. The phase of the moon was declining, so the eastern edge began to look quite comfortable. There was so much ripple that there was no joy at all in the large enlargements, but it was worth admiring this as well. Langrenus, on the edge of Mare Fecunditatis, stood out handsomely, as did a few others (Mercurius right in the shade, as well as Endymio’s elegant and stand out from the picture in some way next to Lacus Temporisk (Lake of Time)). I grabbed a picture on my cell phone from the eyepiece to commemorate my observation trip. The moon was yellow, the picture was bla...

Moon

25.7.2021 at 01.37 - Vantaa, Lammaslammen ranta (V)
Paula Wirtanen, Anne Wirtanen, Ursa (Helsinki)

It all started when at one time at night we saw the Moon ushering inside the living room window. That's where you get the picture! The moon was quite low and in the backyard it was visible behind the trees: to take a photo I had to go a little further. The shore of the sheep pond was atmospheric. The moon was low, Jupiter stood out bright from the already quite dark sky, and Saturn also stood out near the moon's glow in one direction. The telescope was not included in the trip this time. During the same walk, one could also observe possible night clouds (separate observations from thes...

Hercules, Atlas

16.5.2021 at 23.15 - 23.20 - Vantaa, Pähkinärinne (IV)
Paula Wirtanen, Ursa (Helsinki)

At the same time I observed another glimpse of the handsome crater duo Hercules and Atlas. In the middle of the Hercules G crater stood out clearly, no details stood out from the Atlas.

Fracastorius, Piccolomini, Rupes Altai

16.5.2021 at 22.55 - 23.15 - Vantaa, Pähkinärinne (IV)
Paula Wirtanen, Ursa (Helsinki)

The crescent moon was inviting-looking outdoors, so not when the telescope piled up and detected. The air was warm and the May sky was very light, fortunately the Moon can be seen very well even at dusk. Seeing, however, was not the best, even though the Moon was quite high. The flicker was already noticed at 60x magnification when examining the overview. However, I put a 10mm eyepiece in better detail to see and the 150x magnification was still more or less usable for detection. As a destination, I chose the environment of the Nectar Sea, which I admired before. Fracastorius (L21) stood out b...

Agrippa, Godin, Rima Hyginus, Cassini

19.4.2021 at 22.00 - 23.10 - Vantaa, Pähkinärinne (IV)
Paula Wirtanen, Ursa (Helsinki)

The terminator again had a great view. I’ve been trying to find a suitable moment to see a little pighead reminiscent of exploring Cassini and now it came. The promised chart-composing line continues, meaning I artistically regret the shock I caused to the eyes of the talented. Agrippa and Godin are perhaps a little lesser known craters. Now, however, they were quite noticeable. It is noteworthy that these did not appear perfectly round, especially in God’s almost triangular condition. The dashed line means the lighter edge portion of the other surface, the shadows of the base, as seen. The sh...

Theophilus, Cyrillus ja Catharina

18.4.2021 at 22.30 - 22.45 - Vantaa, Pähkinärinne
Paula Wirtanen, Ursa (Helsinki)

The crater trio was nicely visible. On the basis of Catharina, it clearly separated the Catharina P crater in a slightly ghost-like manner, on the basis of Cyrillus, it somewhat separated the central mountain as a small pimple and the slopes of the bottom. Theophilus showed the central mountain. Seeing reasonably good, 36% illuminated by the moon and the ground was still clearly separated. Pictured north up, east right. Save note that spring is coming. For the first time this year, I even had a hot spot when I saw it, and so the night owl was flying and there seemed to be a few more owls in th...

Sabine & Ritter, Arago alfa ja beeta

18.4.2021 at 22.20 - 22.40 - Vantaa, Pähkinärinne
Paula Wirtanen, Ursa (Helsinki)

Seeing was great for once and I got a good opportunity to explore the Sea of Tranquility (Mare Tranquillitatis). The purpose was to study the crater pair Sabine & Ritter and the Arago crater with its domains. It would always be better if Lamont's ghost crater also happened to appear. Sabine and Ritter showed up pretty well. I studied landscapes at 250x and 300x magnifications, 250x was clearly better, although the image looked pretty stable. The craters themselves looked like, well, identical twins, but finding the cracks in the bottom went a little dripping. However, I clearly separated t...

Janssen

16.4.2021 at 22.00 - 22.30 - Vantaa, Pähkinärinne
Paula Wirtanen, Ursa (Helsinki)

The moon was high and the grove owl also reminded us of its existence. Sadly, Seeing was a little crappy again and there was some haze in the sky, forming a light gauze around the crescent moon. However, the Earth stand out clearly and yes, the Moon in the telescope was also worth admiring. Janssen and its surroundings stood out particularly well from the craters. Janssen is a traditional older crater, quite damaged and worn. Just near the terminator you can distinguish one sun from another nice as well as a lot of satellite craters. Of these, Janssen K stood out very clearly, as did Lockyer o...

Mare Crisium

15.4.2021 at 22.00 - 22.30 - Vantaa, Pähkinärinne
Paula Wirtanen, Ursa (Helsinki)

The crescent moon was still at a fairly good height after dark. The ground was clearly distinguished and in the case of such a narrow sickle my intention was to detect Mare Crisium (L10). It was just nicely displayed in its entirety in the lighted area. However, seeing was rather poor, 3-4 (/ 5). The 25-millimeter eyepiece perfectly displayed the entire Moon at 60x magnification, and the country was worth admiring. At a slightly higher magnification of 150x, detection was already quite difficult when the vibration was disturbed. However, with lower magnification factors, I was able to make a s...

Mare Nectaris, Lacus Somniorum

18.3.2021 at 20.30 - 21.30 - Vantaa, Pähkinärinne
Paula Wirtanen, Ursa (Helsinki)

The rather narrow crescent moon looked great. Mare Nectaris was just on the border of light and shadow. The low, slightly flawed Fracastorius cast a little shadow and Beaumont was almost completely in the shade, only the ramparts visible. What made this special was the appearance of the "Beaumont isthmus" quite dark, compared to the surface of the mare area. The most famous sites in the area (Theophilus Trio) were still on the other side of the terminator, and behind the terminator were only the edge ramparts of Theophilus, followed only by darkness. The attached drawing is a rather schematic ...

Archimedes

21.3.2021 at 21.00 - 21.32 - Vantaa, Pähkinärinne (V)
Paula Wirtanen, Ursa (Helsinki)

Moderate seeing and a cold gust of wind were a nuisance upon detection. The terminator was in a very great position, exposing the play of light and shadow from the eastern edge of Mare Imbrium. The Archimedean area was one of the finest I have ever seen as the ramparts cast relatively long shadows on an otherwise flat bottom (I did not see bottom craters). Mons Piton cast a long shadow, as did Aristillus and Autolycos, who were included in the observation drawing, the central mountain was visible from the above. It was worth admiring the Moon, it took a perfect hour and a half. Surprisingly co...

Fra Mauro

22.3.2021 at 21.43 - 22.00 - Vantaa, Pähkinärinne
Paula Wirtanen, Ursa (Helsinki)

The intention was to spot the Fra Mauro area as early as December, when I was writing an article in Zenith to commemorate the fiftieth anniversary of the Apollo 14 flight. However, the weather elf disagreed very much with my intention to include a fresh observation in the article, and I was only able to return to exploring the area now. The air was great. The temperature was a little on the frosty side, but was quite calm and didn’t feel particularly cold and didn’t even need gloves. So I decided to try drawing observation of the object. A quarter went to the observation, some more still in th...

Theophilus, Cyrillus ja Catharina

19.3.2021 at 20.30 - Vantaa, Pähkinärinne (IV)
Paula Wirtanen, Ursa (Helsinki)

The crescent moon appeared to the yard exceptionally inviting. It was clear for the second night in a row! I had left the telescope pre-assembled from Thursday's observation, so not when I wonder. This time I also took a camera body with me to practice photographing the Moon. The location of the crescent moon was great. It was located between Mars and Taurus Aldebaran, the country house was still visible. I took a few pictures of the Moon and a video clip (video at 8.30pm). Personally, I can't take all the credit for the end result, because I sent the video to be stacked and sharpened ...

Mare Nectaris, Janssen, Sinus Amoris, Palus Somni

3.11.2020 at 22.20 - 22.45 - Vantaa, Pähkinärinne
Paula Wirtanen, Ursa (Helsinki)

After a successful observation of Mars, I practiced imaging the Moon again. Great air, though I didn’t have the main imaging equipment with me. However, the moon looked so clever that I took a few small memories of the sighting. One picture shows the surroundings of Mare Nectaris. In the second image, the edge of Mare Crisium peeks just behind the terminator, Sinus Amoris (Bay of Love) and Palus Somni (Swamp of Dream) stand out in a recognizable way. The third image is the southern part of the Moon. Tycho appears with its rays, but the crater Janssen is suitably on the terminator. It was nice ...

Kuu ja Mars

2.10.2020 at 23.53 - Vantaa, Pähkinärinne (V)
Paula Wirtanen, Ursa (Helsinki)

The moon and Mars were close together in the night sky. A very inviting looking couple.
