Aleksi Ruotsila, Jyväskylän Sirius

Heart mist shot with dual-narrowband filter and color camera. The stars are from the data recorded with the light pollution filter a year ago: they are not very satisfied with them, but the colors were better than with the narrower filter.

On isoja projekteja, ja sitten on isoja ja työläitä projekteja. Tämä projekti oli kohtuullisen työläs: Sydänsumu ei olisi mahtunut kuvakenttääni edes 2 paneelin mosaiikkina. Päätinkin tehdä neljän paneelin mosaiikin (2x2). Neljä paneelia, joissa kussakin on 6 kanavaa: SHO+RGB. Kussakin paneelissa on valotusta seuraavasti:Ha: 3,5hO-III: 2,5hS-II: 3hRGB: 1h= 10hYhteensä kuvaan kertyi valotusta tasan 40 tuntia, mikä on itselleni uusi ennätys. Toinen ennätys meni siinä monenako yönä yhtä kuvaa on valotettu: Tähän projektiin kertyi dataa 17 eri yöltä, alkaen 21. Marraskuuta, sisältäen mm. kaikki jo...

Antti Taskinen, Joensuun Seulaset

Very few have had the opportunity to watch or photograph the starry sky in recent months due to cloud cover, at least in Joensuu. One clear night was in early December, I used it to photograph Heart Nebula (IC 1805). Fish head mist (IC 1795) was included in the picture as well. EDIT: I was still working with the image data and I ended up with a slightly different color scheme and also a higher quality result in my opinion. I switched it to the main image and the second image of the previous version.

Part of the Heart Nebula (IC 1805) and the Fishhead Nebula (IC 1795, bottom right), located in the constellation Cassiopeia about 7,500 light-years from Earth. I photographed this with an Optolong L-eXtreme narrowband filter and processed the second image in a way that mimics the color scheme of the famous Hubble Space Telescope. Exposure for exactly 3 hours.

Last season’s Picture of My Heart Mist left me bothering myself, and left a lot in my tooth cavity. I wanted to give this object a new opportunity by describing more data and using new things learned in reading. I got used 7 hours ago a year ago, and in addition I shot 8 hours for narrowband and an hour for RGB stars, now that the last nights have finally been weathering. In total, a 16h exposed final image was created. The camera had rotated so much in the adjustments at the turn of the season that I “had to” crop the view to this center. It doesn't hurt because that is such a beautiful a...

The heart and soul fog stood out moderately well with a digital harrow at a focal length of 135mm. Subsequent exposures are then with longer optics, and it was not worth inoculating them here.

I immortalized Heart and Soul Nebula in a wide angle portrait. With a modified SLR, you can get a lot out of your subjects even with relatively short exposures. I think this subject is very spectacular and with a short focal length, both mists fit nicely into the same image. At the bottom left is the other half of the double set of Perseus.

Heart fog center (Merlotte 15) imaged with Ha and OIII narrowband filters. A total of about 19 hours of exposure. There are so many stars in the area that in a broadband image, the details of the fog are easily obscured behind the stellar abundance, so filters that emphasize the fog are in place here. From Finland, the subject is always in the sky, so it's easy to shoot long exposures (as long as the weather allows). Exposures collected over four nights between New Year and early February. The almost full moon in the sky on some shooting nights did not prevent narrowband shooting. The imag...

For a long time I was able to photograph the deep sky. I chose a fog of heart and soul, which was more than two years old since the previous shooting. A small setback came when the camera did not respond to the timer wire release, apparently the wire was broken. I then had to resort to an old simple wire trigger that had to start and stop each exposure manually. I then sat for a couple of hours exposing the pictures, but luckily it was good to follow, over the phone. Finally, I noticed that the lens of the lens was fogged and when I stacked I had to discard half of the pictures, but the good r...

On the merits of a clear night, I was able to test the new shooting set again. This time I moved the stand from the grass to the hard ground and the tracking improved considerably. That is, the grass gave up so much that the polar sight shifted according to the focus of the shooting head. MGEN worked great until the clouds came to disturb after a couple of hours of exposure. For some reason, the guider did not survive this, but after the clouds disappeared, the shot was not completely sharp for many. Eventually I got 50 piles of 180 second exposures at ISO800. The subject is so bright that thi...

I had not previously exposed the Heart and Soul Mist through the H-alpha filter and now I decided to try despite the unstable weather. Most of the screens flew into the trash due to the clouds but considering the total exposure time, the mists came out surprisingly clearly from the background. In addition to the hydrogen nebulae, of course, the double set of Perseus is also pictured in this short focal length.

In the summer, I upgraded my SCT tube to a bigger model after buying a C925 from Ursala. I used the faults of summer vacation days to collimate the tube with laser laser and this picture was supposed to be just a test, but since the stars in the corners were already starting to look pretty good, this now became a complete whole - the first light on the C925.

Taken the night between Thursday and Friday. The sky is already starting to be dark enough to shoot, and this gem of the sky was found in the north / east sky, suitably holl. The image is thus taken with narrowband filters, and combined from Ha and OIII samples into an RGB image. The second image is also the black and white image of the Ha filter.

Heart mist is a classic destination in the winter sky. So, now is June? Yeah, sometimes in these projects a little stretch :-). The material for this image had to be filmed during other projects during November / December, and now it finally got the attention it deserved from the processing queue (which is therefore not yet empty). This emission fog range is very wide, the image field would fit horizontally for five full months. Even when you could see these with the naked eye, there would be wonder in heaven! In the second and triple images, details of the Melotte 15 constellation engraved in...

Fortunately, there is an f1.4 lens that has time to collect enough photons in a tolerable image, even in a short time (just over 20 minutes). The wide-angle view shows several classic objects that have also been photographed through a telescope. Heart and Pacman nebulae were the first successful subjects when I started an astrography hobby a couple of years ago.

Despite the strong gusts of wind and the full moon, I was forced to get to shoot when the opportunity arose for a long time. Heart Mist was selected as the target. With a meter focal length, the entire fog doesn’t fit in the picture, so it took a while to come up with a good composition. In this picture, the total exposure is just over 5 hours.

My own favorite heart fog and gauze fog, which I have long wanted and longed to photograph, were selected for the night's subjects.

At the edges of the Portuguese heat wave, our thermometer showed 55 C degrees at its best (or worst). Even at night, the sky temperature was about 7 degrees warmer than normal, and seeing was more or less bad. The sky was covered with a thin thin gauze of moisture. I still couldn’t bear not to shoot, and especially I didn’t mind not editing the image on my laptop in the mood of a holiday trip.

So it has been autumn cloudy to keep every bright evening take advantage of even if it hits Christmas Eve! Well, it was possible to shoot the stars while eating ham and Christmas carols, with the camera and tripod working automatically. At the same time, the camera was tested when I modified it again a couple of weeks ago. Namely, I also removed another Canon original filter (its outer one) because I suspected it was causing reflections on bright stars along with the Baader filter. Now the reflections are no longer visible, so the suspicion was right and the operation was worth it. The downsid...

The cropping of the image may be a bit unusual, as it has a piece of Heart Nebula, but the actual object was IC 1795. IC 1795 is also known as "Fish Head Nebula" Exposure to the pile for a good 10h.

After a break of more than a year, I was able to photograph the deep sky. Heart and soul mists were selected as targets because they are well suited for that UHC filter as emission mists. Without it, it is quite impossible to describe large-scale objects from Helsinki.

With my new autogued 347mm telescope + modified 650D + CLS filter, I took 30 360-second exposures with ISO400 sensitivity and the same number of possible corrections (dark, flat, dark flat and bias).

The tracking accuracy isn't quite right there yet (inclination + pole orientation), but those stars aren't terrible right now. I’ve never before combined luminance and rgb images, nor have I combined H-alpha. Yes, I got a twist for a while to get something sensible combined. Overall, though, I'm happy with the picture and that can be said to be a win-win. I wonder if the combination of different image data will gradually become familiar. Even when you get cool...

Pictured IC 1805 Heart Nebula. Located at night time thus fall almost directly above. The location of the subject brought some additional challenges to the preparations for the shooting, such as aligning the image area and searching for a tracking star from an awkward position (camera screens almost directly toward the ground). In addition, it had to be ensured that the tripod did not "drive" the camera into the tripod structures later at night.

There are only a few stunning emission mists on the Perseus branch, and Heart Mist is one of them. Variations in the gas density of the subject appear as brighter and dimmer points, and the subject is easy to locate in the viewfinder image due to the bright tip of the west. In addition to the fog, there is also an open constellation with the same design.

I experimented with a joint portrait of the Heart and Soul Nebulae and the Perseus Twin Group above the lights in the center of Järvenpää. The splendor of the constellations was not surprising, but the red sensitivity of the camera certainly helped bring out the fog. There may have been some light pollution gradient left in the image, but due to the abundance of the star field, I did not attempt to remove it.

The brightest night of the year, light pollution just hurt. The picture shows the most famous sites of Cassiopeia and Perseus.

The "heart of Christmas" was chosen by chance to suit the time because in a very awkward weather you had to find something to describe as high as possible near the zenith. The clouds were constantly harassing me and that’s why with 2x2 binning I am trying to shorten the exposure times. Still, data accumulated in less than half of the recording time itself. Pictures main image , annotations and AstroBin . The third image of the observation is the pseudoluminance formed from the Ha, O-III, and S-II data.

The constellation IC 1805 of the Cassiopeian I photographed on the last nights of October. The fog is known as the Heart Fog and it is the heart-shaped one, but in this image the shape does not appear because the object does not fit in part in the field of my imaging system. The open cluster of a few stars in the middle of the nebula is Melotte 15. The gas and dust in the region of the constellation are arranged in tense shapes that are like a branch of a tree. The fog and crowd are 7,500 light-years away and belong to the spiral branch of the Milky Way known as the Perseus branch.

The Sharpless catalog item is this one too (Sh2-190), although better known as the "Heart Nebula" IC 1805. Quite a bright item and in that sense easier to describe than many other Sh2 items. I’ve photographed heart fog before a couple of years ago, but then with a longer focal length. Exposure in the picture for a total of 12h. https://www.flickr.com/photos/67018317@N07/15686850171/in/photostream/lightbox/

The proper joint portrait of Soul Mist (IC 1848) and Heart Mist (IC 1805) definitely had to be captured when the Star Rock sky made it possible. The trail was on a completely different level than a few weeks back in Järvenpää, although there is nothing for it without filters that the stellar Milky Way is a bit overwhelmed by the splendor of fog. These are also very red-winning targets. In the picture, Soul Mist is on the left and Heart Mist is on the right.

Now the light of the Moon and the thick fog were fought. However, I got exposed for a moderately long time over 6 hours. The very narrow 3nm passband narrowband filters did well against lunar flare. Figures 1 and 2 and AstroBin .

I returned to this same subject again after adjusting the imaging equipment to have a reference picture . The screws were checked and tightened and the camera was moved 1mm backwards with spacers. So even this pipe needs to be slightly duned at the beginning. The weather provided only a couple of hours of shooting. Figures 1 and 2 .

Next to the comet was this emission mist that has not yet been described. This now became such a quick blast, and not even the target is fully visible. I call this a ‘broken heart’.

I managed to take a few test shots with the refurbished imaging equipment. Unfortunately, the wind and clouds were quite a nuisance and then forced me to quit after a few squares. Maybe you should have just watched repos and lightning or the Moon ;-) Next time, maybe more exposure time or even color pictures. Figures 1 and 2 .

IC 1805 (Heart Nebula) in the constellation of Cassiopeia at a distance of 7,500 light-years. The sad wind the night before had prevented everyone from attempting to describe anything from the south to the darkest part of the sky, and tonight the weather type with the direction of the wind was quite similar. The object was therefore selected from the northeastern part of the sky where the echo of the setting and rising of the Sun is still visible through the night. After two o'clock, the exposures began to ruin when the dome and tube had to be turned to the southeast and the wind got to ca...

Just before dawn, there was less than an hour to shed light on this. Both Heart Mist and Soul Mist can fit in the same image field. After exposing the flats and unloading the equipment home? Ehei-not this time but to work!

IC 1805 (Heart Nebula). After the mist of the soul, there was the Heart of Nebula. Should have taken between the flats and refined again or at least do the latter. The moon was already in the patterns at this point in the evening. Picture .

Sunday’s star show at the TaUrsa observatory was quite lively thanks to the bright weather and I was left to try out the shooting with “pre-heated” equipment after that. And of course when it comes to a windless and cloudless night then it has to be with a full moon. As a telescope, the Quadruplet offered a wider viewing angle than before with a 420mm focal length, and I got the AP900 tripod to obey "pulseguide" control without a normal ST4 yard. In the fall, I had headed for a tripod for a full three nights watching the stars flow and here I tested it a bit. However, the picture didn’t turn o...

In late September, I photographed for two nights (September 14-September 15, 2013 + September 24-September 25, 2013) the central area of Heart Nebula (IC1805), where the open constellation of Melotte 15 also resides. The angle of view of my imaging tube from the sky is about 40'x30 ', so the wider Heart Nebula was now almost completely out of the field of view (only this downtown nebula was left behind the constellation). The processing of the image into the final image has been delayed for various reasons, but let me end up getting this in roughly the look I want. The total exposure t...

IC 1805 (Heart Nebula, Sh2-190) in the constellation of Cassiopeia. I went to nail the association’s HEQ5 stand in place to the floor of the Dome and made a preliminary orientation that I tested here (there is still room for improvement). For a long time a moonless night but the clouds disturbed and stopped the business at midnight on land. The advantage of this season is that it was already observed after 18. The visit of the constellation course participants in the hood interrupted the exposures for half an hour. Picture .

IC 1805 (Heart Nebula) in the constellation Cassiopeia. The tube again pointed almost to the zenith with this target at the end of the session but luckily there was no need to go over the meridian. The integration time was 6 hours. Picture .

IC 1805, Heart Nebula, Heart Nebula, Sh2-190. A kind child has many names. This item does not fit anywhere in the image field of the used shooting configuration. Now the Moon was almost directly in the same direction, albeit much lower. IC 1805 is located high in the constellation of Cassiopeia and rose to almost zenith at the end of the description. The humidity didn’t bother me this time but the wind was really strong and gusty. The monitoring revealed completely new problems. And of course the Moon hurt. I favored OIII and SII exposures less. I still have to come back here from heaven next ...

Black lace Close-up of the edge of the Heart Nebula , IC 1805 . The triangular shape lined with black lace extends towards the Mel 15 constellation. Latest picture from last Tuesday. This has been one of the worst winters in terms of shooting weather, I just got just scraped off for six hours of exposure for this subject in poor transparency, though seeing was better than the season in general. I have photographed Heart Nebula formations several times this season. The long 2000mm focal length opens up views of the details and allows you to showcase interesting areas. IC 1805 is located in the ...
