M45 Star cluster is a favorite in lot of meanings. Its hard work to adjust technique for properly exposings and keep details . First waves of photagraphies I made I got halos of the main stars, then I remade it with lower iso and shorter expo´´´ s, then it disappeared (more or less).

However, M45 have a long history and played a star roll in many folklores and religions (Maya, Arabic, Persian, Chistians, Chinese, Japaneses etc). This is the closest star cluster we have to Earth.
If we speak in meaning of where we can find another unknown civilisation on another planet system Or where the angel is on the sky - it is Pleiades (its mentioned several times in Bible) also mentioned in Coran. Interesting..

Seven sisters with two parent is that we see normally in the sky with our bare eyes. In the telescope and camera we highlightning over 1300 members in this star cluster. The group is floating/passing thrue a spacedust area wich give luminousity. The stars is mainly blue younger stars. It will be interesting to enhance in narrow spectra and try to find some more galaxies behind it :-)

150 expos of 45 sec in 800iso-mode was the ingrediens in this picture. It will be enhanced with more in near future.
