M45 The Pleiades
Photographed at night of 11. and 12. december.I modified my Omni XLT150 and replaced stock focuser to better Crayford type focuser. Now I´m able to use 2" equiment. This photo has been photographed with Baader MPCC coma corrector. Collimation is still little bit out of line and you can see that stars looks like waterdrop.
M45 is an open star cluster containing middle-aged hot B-type stars located in the constellation of Taurus. This open cluster detached with a strong concentration toward the center, has a large brightness range and is rich in stars (more than 100 stars). It is involded with dust that forms a faint reflection nebulosity around the brightest stars. (messier45.com)
