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.

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.
