Globular cluster M53 - 13 April 2009
There were several months without proper sky. The weather was really very bad. I decided to look at globular cluster M53
After some preparations we decided to try a new CCD camera. This camera has full frame CCD chip. It is really big.Globular cluster M53 was chosen for testing. In spite of the fact that the weather changed during our testing, we carried out a series of short frames. So this is first light.
This globular cluster (M53) is not too large. Bright central part is only about 2', but entire cluster in diameter is about 13'. Distance from the Earth is about 58,000 lights years and it was discovered in 1775 by Johann Elert Bode.
