Moon

26.2.2020 at 19.15 - Kankaanpää
Tero Hirvikoski, Ursa (Länsi-Suomi)

A fine sickle moon sank towards the horizon.

LDN 1495

22.1.2020 at 20.00 - Kankaanpää
Tero Hirvikoski, Ursa (Länsi-Suomi)

A few years ago, I photographed a vast Bull’s molecular cloud with camera optics, and later, while watching the prey, I noticed this peculiar detail. I returned to it now with my telescope, the close-up provided by which brings out the confusingly staring gap of reflective and dark mists. The target is located on the edge of the dark fog LDN 1495. The reflection fog at the bottom of the eye is by no means particularly dim, but perhaps a little surprisingly, it is not listed on any of the more general lists. The same is true for the second reflection fog from the eye to the top left. Full size ...

M45

16.1.2020 at 20.00 - Kankaanpaa
Tero Hirvikoski, Ursa (Länsi-Suomi)

The open constellation M45 or Screeners photographed on 16-17.1. the night between. The total exposure time was just over six hours. Full size image and more detailed teas in my Astrobin gallery .

M33

5.10.2019 at 22.00 - Kankaanpaa
Tero Hirvikoski, Ursa (Länsi-Suomi)

I chose Triangle Galaxy M33 as the first light for my new telescope. Despite the hard work, the collimation is not in place, but the car collimator has already been ordered. More detailed shooting information and a full size image can be found in my Astrobin gallery .

M31

19.11.2018 at 05.00 - Kankaanpää
Tero Hirvikoski, Ursa (Länsi-Suomi)

The large galaxy in Andromeda is huge in angular diameter, so it doesn’t fit anywhere near the field of view of my imaging equipment. I therefore decided to spend several nights building a mosaic of four images of this great object. The total exposure was as high as 33.5 hours, which is probably my personal record. Admittedly, due to moonlight and occasional cloud cover, much of the exposure is of rather poor quality. More information and full size image in my Astrobin gallery .

NGC 7538

15.10.2018 at 05.00 - Kankaanpää
Tero Hirvikoski, Ursa (Länsi-Suomi)

NGC 7538 shines in the middle of a large area of emission fog. In addition, the picture shows a couple of dark fogs. Filmed October 10/11 and October 14/15. More detailed shooting information and full size image in Astrobin .

NGC 6992

29.9.2018 at 02.00 - Kankaanpää
Tero Hirvikoski, Ursa (Länsi-Suomi)

The first subject of my somewhat sluggish filming season was the eastern branch of Harsosumu, NGC 6992. The filming dates were 7/8 and 28/29 September. More details and full size image in Astrobin .

NGC 3610, NGC 3642

16.3.2018 at 20.45 - 04.30 - Kankaanpää
Tero Hirvikoski, Ursa (Länsi-Suomi)

A few Big Bear galaxies photographed on two nights 14-16. March. A full size image and specifications can be found in my Astrobin gallery .

NGC 2419

21.2.2018 at 20.00 - Kankaanpää
Tero Hirvikoski, Ursa (Länsi-Suomi)

The spherical constellation NGC 2419 in the constellation of lynx is also known as the Intergalactic Wanderer. It has since become clear that, despite a distance of 300,000 light-years, it is tied to the Milky Way. NGC 2419 is one of the brightest and most massive spherical constellations in our home galaxy. More detailed shooting information and a full size image can be found in my Astrobin gallery.

Holmberg 124

19.2.2018 at 20.00 - Kankaanpää
Tero Hirvikoski, Ursa (Länsi-Suomi)

A group of a few galaxies, Holmberg 124 photographed on two nights 19-21. February. The largest of the galaxies is NGC 2805. More detailed shooting information and a full size image in my Astrobin gallery .

NGC 2146

3.2.2018 at 19.00 - Kankaanpää
Tero Hirvikoski, Ursa (Länsi-Suomi)

A giraffe constellation fun-looking galaxy NGC 2146 pictured 3-6. February. The total exposure time was just over 18 hours. More information and a big picture can be found in my Astrobin gallery .

Cederblad 30

19.1.2018 at 18.30 - Kankaanpää
Tero Hirvikoski, Ursa (Länsi-Suomi)

Cederblad 30 reflective nebula in a large molecular cloud of a bull photographed on two nights 19-21. January. The transparency of the sky was lousy across the line and some of the screens ended up in the trash, but barely usable data accumulated for 9 hours. A full size image and more detailed shooting information can be seen in my Astrobin gallery .

Rare halos

11.1.2018 at 14.42 - Kankaanpää (IV)
Tero Hirvikoski, Ursa (Länsi-Suomi)

Handsome halos caused by ice mist in Kankaanpää as photographed with a mobile phone camera. Of these, I only recognize 22 and 46 degree tires as well as the sun pillar. The phenomenon was local and showed no trace less than a kilometer from the scene.

IC 1795

25.11.2017 at 19.00 - 05.30 - Kankaanpää
Tero Hirvikoski, Ursa (Länsi-Suomi)

The object in the picture is part of a larger nebula complex known as Heart Nebula in the constellation Cassiopeia. The filming dates were November 25, 2017 and December 21-22, 2017. Even less exposure would have been sufficient for the main subject itself, but a total exposure time of ten hours made processing easier and exposed the dimmer mist to the environment. More detailed shooting information and a full size image can be seen in my Astrobin gallery .

IC 59, IC 63

18.11.2017 at 21.15 - 04.45 - Kankaanpää
Tero Hirvikoski, Ursa (Länsi-Suomi)

Fogs visible around the gamma star of Cassiopeia photographed on the night between 17/18/11. More detailed technical information and a full size image can be found in my Astrobin gallery .

Sh2-155, vdB 155, LDN 1210

30.10.2017 at 19.00 - Kankaanpää
Tero Hirvikoski, Ursa (Länsi-Suomi)

I photographed this foggy area of Cepheus on the night between 30 / 31.10. There are several deep sky objects in the image area: the red glowing emission fog is Sh2-155, the dark fog is LDN 1210, and next to it is a reflection fog vdB 155. Briskly over half of the Moon interfered with shooting until midnight and brought its own challenges to image processing. More details and a full size image can be found in my Astrobin gallery .

Sh2-140

21.10.2017 at 00.00 - Kankaanpää
Tero Hirvikoski, Ursa (Länsi-Suomi)

I photographed this fog complex visible in the direction of Cepheus on two October nights. The dates were 16 / 17.10 and 20 / 21.10. The transparency of the sky was occasionally poor due to fog. More detailed shooting information and a full size image in my Astrobin gallery .

Tero Hirvikoski, Ursa (Länsi-Suomi)

A dark mist B343 visible against a rich star field and illuminating nebulae photographed on the night of September 29-30. The weather was a bit bad and Kuukin bothered me, but this was still a nice little project. More information and full size image in my Astrobin gallery .

vdB 154, Sh2-150

26.9.2017 at 00.00 - Kankaanpää
Tero Hirvikoski, Ursa (Länsi-Suomi)

Reflections and emission nebulae of Cepheus photographed on two nights 25-27. September. More detailed shooting information and a full size image in my Astrobin gallery .

NGC 6960

23.9.2017 at 23.00 - Kankaanpää
Tero Hirvikoski, Ursa (Länsi-Suomi)

Here in Nurinniska, the first subject of the filming period was the western branch of Harsosumu. The exposure time totaled more than three hours, but the moisture condensed between the camera and the comma equalizer forced me to throw a large pile of squares out of the stack. That problem has been a nuisance in the past, but now it’s finally in treatment because I punched it in and installed a small heating mat in place. More information and a big picture in my Astrobin gallery .
