IC 1805 - 5.2.2013 at 23.00 Oulu Observation number 10712

Visibility V / V


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 constellation of Cassiopeia at a distance of about 7,500 light-years. Located in the middle of the nebula, a star cluster known as Melotte 15 makes the nebula gases glow with its own light and its radiant pressure twists the gas clouds into imaginative shapes.

The first image shows the fog in the HST palette, the second in visual colors. The third image is a two-frame mosaic, in which I combined the Melotte 15 image I had previously photographed into this new shot. The last figure shows the area shown in the most recent image in a broader context.

Uskomattoman hienoja kuvia.

Ei täällä kaakkoisnurkallakaan montaa pilvetöntä yötä ole ollut.

Sydänsumun sisällä keskikirkkaus Melotte 15 ollut aiemmin esillä - nyt lisätarkennuksesi taustaan. Sydänsumun asento saa muutakin tulkintaa "mielikuvituksellisiin muotoihin", josta alaosan pussin sisällön tummuus vielä tarkentamatta.

Teit tänään 17:40:44 uusimman lisäyksesi Sydänsumu -keskustelussa ja katsoin kuvaa tarkemmin, jossa ylimmän kuvan keskellä keltaisen kohouman päällä tasapainottelee henkilömäinen hahmo. Em. pussin sisältöäkin suurennoksesta katsoin kuin olisi sikiö sisällään kaareutuneena.
