Show full image A very beautiful nebula that was previously unknown to me. It consists mostly of hydrogen gas which glows with a dark red color. There are also areas with carbon-rich dust. These glow with reflected light and appear as gray-blue areas in the center of the image near the bright star. The distance […]

Show full image The horsehead nebula is located in Orion near the bright star Alnitak in Orions belt. It is a region of black dust covering a part of the much larger red emission nebula called IC 434. This whole area is a region of heavy star formation and is part of the much larger

Show Full image This is my version of the wellknown Rosette nebula, or NGC 2237. It is located just east of Orion in constellation Monoceros at 5 000 lightyears distance and it is about 130 ly in diameter. The bright stars in and around the nebula excites the atoms in the nebula gas, and this

Show full image This is a nice target for small telescopes. The surface luminosity is rather high which makes it comparatively easy to image. It is located in Canes Venatici at a distance of about 30 million light years. It is interacting with the close companion NGC 5195. It is believed that the two galaxies

Show full image These galaxies are about 12 million light-years from us. They are part of the so-called M81 group, and are thus to be regarded as relatively close neighbors to us. M82 (top) is a so-called Starburst galaxy, where a very intense new formation of stars is taking place. At its core, stars are

Visa större bild. Denna galax har jag inte förrän alldeles nyligen insett hur förhållandevis stor och ljusstark den är. Dess vinkelutbredning på himlen är ca 1/3 av Andromedagalaxens, och den ska kunna vara möjlig att observera med blotta ögat under goda förhållanden. Jag har dock aldrig försökt detta, och detta är också första gången jag

Visa större bild Detta är min första bild där jag använder ett guideteleskop. Detta innebär att teleskopet följer en guidestjärna och det blir möjligt att använda betydligt längre exponeringstider. Jämfört med tidigare bild så syns detta tydligt med bättre kontrast och mer färger. Om bilden: Exponering 12x240s ISO 1600. Processning i Astro Pixel Processor och GIMP
