Messier 45 (M 45) - Pleiades (Seven Sisters)

Introduction | Map | Own Observations | My Own Photos | References

On this page I collect my observations of the open star cluster M 45 (Pleiades, Seven Sisters) in the constellation Taurus / Bull.



I know the Pleyades (M 45, Seven Sisters) in constellation Taurus / Bull since my childhood. Finding them was therefore no problem for me, especially since they are already visible with the naked eye. They are also a nice object in the binocular, but much more so in a telescope at low magnifications.

February 2017

In a telescope, such as my 4" Heritage 100P, there are, of course, even more stars visible and many of them are almost sparkling. The sight in the GSD 680 8" telescope (on the second day) was even more impressive for me than the one in the 4" telescope (on the first and third day). The same accounts more or less for the Heritage P130 (Feb 26, new moon; Mar 2).
