M68 Globular Cluster

Messier 68 is a globular cluster located in constellation Hydra. The cluster contains more than 100,000 stars and it is approximately 33,000 light-years away from Earth. The best time for observation is between March and July. Observers from Central Europe have disadvantage, because M68 doesn’t raise much above the horizon. Therefore this cluster was one of my primary targets on La Palma, where M68 is much better visible. However, the weather was bad and I only got 40 minutes between the clouds.

M93 Open Cluster

Messier 93 is an open cluster located in constellation Puppis and it is about 3400 light-year away from Earth. My previous attempt to capture this object was not so successful, because M93 doesn’t rise far from horizon in Central Europe. On La Palma is the situation different, but only if the weather allows it. I was partially lucky and a hole between the clouds appeared and I got 44 minutes opportunity to capture this cluster properly.

M83 Southern Pinwheel Galaxy

Messier 83 is a spiral galaxy located in constellation Hydra. It is one of the brightest and closest (15 million light-years) galaxies observable from Earth. On the other hand there are much brighter and closer galaxies, for example Andromeda is only 2.5 million light-years away and M33 Triangulum Galaxy is roughly 3 million light-years away.

Due to the fact that the M83 has very low southern declination (rises not far from horizon), thus it is very difficult to capture from light polluted Central Europe, I decided to take a trip to south. Specifically to La Palma (Canary Islands) and tried to photograph it from there. I had only one clear night out of ten, but together with M68 was this galaxy my primary target and I somehow managed. My plan was to capture more deep space objects, but the weather didn’t allow me.

M61 Galaxy

Spring offers the best conditions for photographing/observing of the galaxies. This is caused by the fact that the constellations Virgo, Leo and Coma Berenices are visible and there are galaxies anywhere you look. This year, I already captured M58 M88 M89 M90 M91 Galaxies, but there are still some galaxies missing, in order to finish Messier catalogue. One of them was M61 (upper left corner). This spiral galaxy is located in constellation Virgo, it has about the same size as our home galaxy Milky Way and it is approximately 52 light-year away from Earth.
