M24 Sagittarius Star Cloud

Messier 24 is spiral arm of our galaxy located in constellation Sagittarius. The region is heavily populated by the stars, which makes you think how big our home galaxy Milky Way is. I captured already few years back, but it would be a pity not to recapture this magnificent star cloud again with slightly shorter focal length and under dark skies of Fuerteventura.

M8 Lagoon Nebula, M20 Trifid Nebula

These two magnificent nebulae are located visually close to each other in constellation Sagittarius. This means we are looking in direction of the galactic core of the Milky Way. Trifid nebula (up left) is a combination of a reflection nebula (blue part), a dark nebula (brown clouds), an emission nebula (red part) and a star cluster. On the other hand, Lagoon nebula (right side) is an emission nebula – giant cloud of ionized HII gas. Due to very low southern declination, it’s very difficult to photograph these deep space objects from my home place in Central Europe. Therefore every time I travel south, I take the opportunity and recapture these nebulae. My first attempt of M20 was done with focal length 917 mm, second one with 630 mm and now I used gentle focal reducer. Focal length 570 mm allowed me to fit both nebulae into the field of view of APS-C sensor size. The picture is an integration of 213 minutes, taken under dark skies of Fuerteventura.

M70 Globular cluster

Messier70 is a globular cluster located in constellation Sagittarius. The cluster is at a distance approximately 29’300 light-years from the Solar System. Neighbor cluster M69 was captured during the same night.

M70 is the 15th globular cluster captured by me on Milos Island – mission accomplished.

M69 Globular Cluster

Messier69 is a globular cluster located in constellation Sagittarius. It is approximately 29’700 light-years away from Earth. Together with Messier70 are close to galactic center of Milky Way (distance between them is 1’800 light-years) and there were two last deep space objects captured on Milos Island. These two were the last missing Messier objects, which I wanted to capture and I was very happy that I managed.

M28 Globular Cluster

Messier 28 is a globular cluster located in constellation Sagittarius. Center of Milky Way takes care about the background, which is filled by many stars. The cluster is 17900 light-year away from the Solar system and it has diameter approximately 60 light-years.

M55 Globular Cluster

Messier 55 is a globular cluster located in constellation Sagittarius. M55 is one of the closest globular cluster, having distance from the Solar System only 17’600 light-years, compared to M54, which is one of the furthest globular clusters (86’400 light-year). I managed to capture these two clusters during single night.

M54 Globular Cluster

Messier 54 is a globular cluster located in constellation Sagittarius. It has been assumed that the cluster’s distance is 50’000 light-years. Recently (1994) it was discovered that this cluster doesn’t belong to Milky Way galaxy, but it’s a part of Dwarf elliptic galaxy in Sagittarius and it is approximately 86’400 light-year from Earth. This means M54 is first discovered globular cluster outside of our galaxy.

NGC6822 Barnard’s Galaxy

NGC6822 is a galaxy located in the constellation Sagittarius and it is 1.6 million light-years from Earth. This galaxy belongs to a local group of galaxies together with Andromeda, Triangulum Galaxy and Milky Way. This galaxy is quite famous, because Edwin Hubble discovered several variable stars in this galaxy. These variable stars can be used for determination of the distance from Earth. Barnard’s Galaxy was the first galaxy with accurately determined distance.

Barnard’s Galaxy is very dim deep space object; therefore I dedicated quite long integration time to it (180 minute) and I chose long exposure time to each frame (300 seconds). Several nebulae are visible on the picture. These are the red spots located at the left side of the galaxy. They are called Bubble Nebula and Ring Nebula and are giant HII regions, where new stars are born.
