Mars

30.7.2022 at 03.30 - 04.00 - Ulvila (III)
Tomi Kurri, Porin Karhunvartijat

The planets are now nicely lined up in the morning sky and for a long time Mars is also very visible. The planet is still far away, but the phase of Mars and some details stood out even visually!

Jupiter

30.7.2022 at 03.00 - 04.00 - Ulvila (IV)
Tomi Kurri, Porin Karhunvartijat

I photographed Jupiter at Pori's Bear Guardians observatory in Ulvila. In the dusk of late July, the planet was already high in the sky. In the early evening, a large red dot was also visible, but the seeing was still poor. So here is the result of the evening.

Saturn

30.7.2022 at 02.00 - 03.00 - Ulvila (IV)
Tomi Kurri, Porin Karhunvartijat

The summer nights get darker and the planets are nicely visible in the light sky. I photographed Saturn with the association's C11 telescope and two different cameras. Visually, the view was really wonderful and several of Saturn's moons stood out.

Supernova 2022hrs

30.4.2022 at 00.00 - 01.00 - Nakkila (I)
Tomi Kurri, Porin Karhunvartijat

Luckily on May Day weekend, it was still so dark that I was able to photograph the supernova found two weeks earlier in the galaxy NGC 4647, located in the sky in the constellation Virgo next to Messier 60. This is the first supernova I have described. It’s pretty amazing to see how a supernova is almost as bright as its entire emogala.

Half-sky auroras

14.3.2022 at 01.00 - 03.00 - Nakkila (IV)
Tomi Kurri, Porin Karhunvartijat

The most amazing northern lights I've ever seen. The sky exploded at night after about 1am, just as I was going to sleep. Thanks to the bear camera, the show was not interrupted, but I hurried to the nearby field to shoot. Visually you really look like a fire and a great treat in terms of photography, with the camera you were constantly rotating in different directions :)

NGC 2174

28.1.2022 at 18.00 - 23.00 - Nakkila (IV)
Tomi Kurri, Porin Karhunvartijat

The moonlit and clear night that hit Friday offered an opportunity to go through new deep sky destinations for yourself. This time the Monkey Head Nebula, located right in the upper corner of the constellation Orion, near Gemini, was chosen as the subject. This emission mist is located at a distance of about 6400 light-years. SkySafari gives the magnitude of the fog at +7.59, so it's a fairly bright destination. The weather favored the whole early evening and I finally got a total of exactly 5 hours of exposure time with a color camera through the narrowband filter.

Barnard 33

25.12.2021 at 22.00 - 00.00 - Nakkila (IV)
Tomi Kurri, Porin Karhunvartijat

On Christmas Eve, the weather brightened for a moment and I was able to photograph one of the most amazing objects in the starry sky, the Horse's Head Nebula in the constellation of Orion. The total exposure time of the image is 2 hours.

Orion and Barnardin arc

5.12.2021 at 00.00 - Kokemäki (V)
Tomi Kurri, Porin Karhunvartijat

Together with the Bear Guards of Pori, we headed to the shores of Lake Sääksjärvi to spend the association's annual Arcturus observation weekend. The weather was favorable and the SLR shook through the night. One of the subjects was the constellation Orion. In a dark place, the arc of Barnard is well visible in this total exposure of less than an hour. The picture also shows the familiar Orion's Mist and the Horse's Mist.

Telescopic comet

9.11.2021 at 00.00 - 00.10 - Ulvila (I)
Tomi Kurri, Vesa Puistovaara, Porin Karhunvartijat

The last observation of the November frost night was the comet 67 / P Churyumov-Gerasimenko. This comet, which moves through the constellation of Gemini, is the same one that ESA's Rosette probe visited in 2014. We photographed a comet at the Ulvila observatory in Pori. I managed to grab a total of 8min exposure from the comet with LRGB filters before the clouds arrived.

NGC 6888

8.11.2021 at 00.00 - Nakkila (IV)
Tomi Kurri, Porin Karhunvartijat

My autumn observation project has been the Sickle Nebula in the constellation Joutsenen. There is a lot of opaque hydrogen mist around the site, which is aided by rapid optics. The total exposure time of the image is almost 10 hours. The camera is a ZWO 183MC Pro color camera.

IC 1396

3.10.2021 at 01.00 - Ulvila (III)
Vesa Puistovaara, Tomi Kurri, Porin Karhunvartijat

A piece of the most beautiful space ... small, but the most famous and described part of the object itself IC 1396. Forecasts for the weather seemed completely unworthy for most of the week, but as if by order for Saturday night, there was a fairly clear observation time! It must have been true to try to take advantage of. The evening went quite calmly, without thinking about major worries - the coffee was consumed almost in a pan and time passed surprisingly quickly. Observations were made at several sites, both at the observatory and remotely. In the "Picture of the Hour" last night's gi...

NGC 281

27.9.2021 at 00.00 - Nakkila (IV)
Tomi Kurri, Porin Karhunvartijat

NGC 281, or Pacman Nebula, located in the constellation of Cassiopeia, is an emission nebula and consists mainly of hydrogen. At a distance, the fog is about 9,200 light-years away from us. I photographed the subject on several autumn evenings and the data was collected in both RGB and narrowband. The total exposure time of the image is 5.5 hours.

M33

15.9.2021 at 00.00 - 05.00 - Nakkila (IV)
Tomi Kurri, Porin Karhunvartijat

During the dark nights of autumn, there was an opportunity to photograph the classic object of the night sky, the M33 of the Triangle Galaxy. This spiral galaxy, 2.7 million light-years away, is part of our galactic neighborhood.

M31

30.8.2021 at 00.00 - 03.00 - Nakkila (V)
Tomi Kurri, Porin Karhunvartijat

The weekend was surprisingly clear for a couple of nights and I got to test a new telescope on this distant galaxy, also known as M31. The distance to Andromeda is 2.5 million light-years. The figure also shows the companion galaxies M32 and M110.

Saturn

26.7.2021 at 01.45 - Ulvila (V)
Tomi Kurri, Porin Karhunvartijat

Saturn, the pearl of the night sky. The planet is visible in the southern sky as early as July. The very calm seeing made it possible to describe the details despite the low height of the planet.

Jupiter

25.7.2021 at 03.50 - Nakkila (IV)
Tomi Kurri, Porin Karhunvartijat

Summer night Jupiter with moon. Used, the busy Meade got into the first true test, a surprisingly good planetary tube. Photographed with 2x Barlow without follow-up. Moons on the left including Europa, Ganymedes and Io.

Jupiter

18.7.2021 at 02.40 - Ulvila (IV)
Tomi Kurri, Porin Karhunvartijat

The start of the season in terms of planetary photography! I drove to the Pori Bear Guard's observatory in Ulvila to photograph the planets of the summer night. Jupiter and Saturn were nicely in the holls and the setting moon brought atmosphere to the evening. The red dot of Jupiter and the shadow of Ganymede on the surface of the planet were well visible, though the seeing was not strange.

Sun

12.6.2021 at 11.43 - Mikkeli, Launiainen (IV)
Petrus Kurppa, Tomi Kurri

During the summer holiday provincial trip in Mikkeli, there was an opportunity to try the DayStar Solar Scout SS60-DS telescope. In the light of the online writings, I didn’t think too much about the performance of a small hydrogen alpine tube at first, but with the first light, the mind changed. Visually, the celebrities and filaments came out nicely. The MacGyver-inspired shooting tuning gave a little foretaste of what can be accomplished with the tube. Today the wind and clouds took the victory from a longer exploration.

IC 1396

11.4.2021 at 02.00 - 03.00 - Kangasala (IV)
Tomi Kurri, Porin Karhunvartijat

A bright April night on the edge of the Milky Way. As the dark nights drew to a close, I decided to photograph the area of Cepheus, with a particular focus on IC 1396, or Elephant Fly Nebula. Next to IC 1393 is Sh2-129 "Flying Bat Nebula". The picture also shows several dark mists. This is my first constellation with a modified full-cell camera. The total exposure time of the image is 54 min.
