Nebulae and star clusters

North-America nebula NGC7000 and Pelican nebula IC5070 in the constellation of Cygnus. Distance 1600 light years. Ionisized hydrogen glows in red color. Photograph taken 5.9.2013 EF100-400 tele zoom objective set to 300 millimeters.

Butterfly nebula IC 1318 in Cygnus. Distance 3700 light years.

Below is Milky Way in constellation of Aquila. There is a dark dust and molecular cloud Barnard 143, with distance of 2000 light years. The picture area in the sky is 10x4 degrees. You can see how Milky Way contains millions of stars. Actually in our Milky Way Galaxy there is about 400 billion stars. The bright star on the left is Altair, with distance of 17 light years. It is twice the size of the Sun.

Below left is NGC2237 Rosette nebula in constellation of Monoceros. Distance 5200 light years. Angular size in the sky is 1.3 degrees. Mass 10000 times mass of the Sun. The bright stars in the middle have born from this nebula.
On the rigth is Horsehead nebula Barnard 33 and Flame nebula NGC 2024 in the constellation of Orion. Distance to Horsehead nebula is 1500 light years. Distance to Flame nebula is 1200 light years. Picture taken with 400mm telezoom objective 30.12.2019 in 340mm focus. Pictures are stacks of 6 x 3 minutes exposures, ISO3200 and stacked with Deep Sky Stacker software.

Below is NGC 1973 Running man nebula, M43 ja M42 in constellation of Orion. Picture taken with Sky Watcher 80/600 ED telescope. Distance to M42 is 1300 light years. There has born about 2000 new stars in area of Orion Nebula. From sharp pictures of Hubble Space telescope it is possible to see several protoplanetary discs around the new stars. So here new planets and solar systems are born.

The center of the Orion nebula M42. The bright four stars are born in this nebula. Photograph taken 17.2.2019 with Celestron 8 F10 focus. Stack 4 x 7 seconds, ISO 3200. The M42 picture on right is taken 27.10.2012.

Below left: M57 in constellation of Lyra. Distance 2300 light years. In center of the nebula there is a white dwarf star. It is what is left from a star, which blow out its outer parts to space at end of its life. The red color comes from ionized hydrogen gas. The greenish colors come from oxygen. Below right: NGC 7635 Bubble nebula in constellation of Cassiopeia. Distance 11000 light years. Photograph taken 12.11.2012 with Celestron 8 F6.3 focus.

M27 Dumbbel nebula in constellation of Fox. Distance 1250 light years. In the center of this nebula there is also a white dwarf star. Photograph taken 7.9.2013 with Celestron 8 F10 focus.

Below are two southern sky objects, places where stars are born, M16 and M17. In Finland these are difficult to photograph since they are close to horizon. Photographs were taken 5th of September 2016 with Celestron 8 F6.3 focus. Exposures 9 times 40 seconds, ISO6400. M16 Eagle nebula is in constellation of Snake. Distance 7000 light years. Hubble space telescope took of M16 the famous picture Pillars of Creation. M17 Omega nebula is in constellation of Sagittarius. Distance is 5000 light years.

Double star cluster NGC 884 and NGC 869 in constellation of Perseus. Distance 6800 light years, Image taken 27.10.2012.

Messier 11, Wild duck cluster in contellation of Scutum. Distance 6200 ligth years. One candidate for place where Solar system was born is open star cluster Messier 67 in constellation of Crab. This cluster has same age as our Sun. And it contains several similar chemical composition stars as our Sun. Distance is 2700 light years. In constellation of Auriga there is 3 open starclusters which are visible with binoculars: M36, M37 and M38. Distances 4100, 4500 and 4200 light years. Also red nebulae IC405 and IC410 are visible. Distances 1500 and 1300 light years.

Below is open star cluster M45 Pleiades. Distance 440 light years.

Globular star cluster Messier 13 in constellation of Hercules. Distance is 25000 light years. This cluster has one million stars. Our galaxy has about 100-200 these kind of globular clusters. These clusters are very old. They were born at same time as our galaxy, about 10 billion years ago. Photograph was taken 5th of September 2016 with Celestron 8 F6.3 focus. Exposures 9 times 30 seconds, ISO6400.
