| M-87
is an elliptical galaxy in the Virgo cluster.  Generally elliptical
galaxies look like a fuzzy ball of light because there are no spiral arms
visible.  M-87 is different because it has thousands of satellite
Globular Clusters and a vary interesting jet of super luminal gaseous material
being ejected from the central core.  Even my images taken with an
8" SCT at f4 show the jet.  I really need to go back and try an image
at f10. | |

 I tried to capture a longer exposure, but at this focal ratio you loose sight of a suitable guide star. The STAR 2000 was able to achieve good guiding on only two of five images I tried. | Scope: 8" LX 200 SCT |

 For this image I applied the AstroArt Gradient filter to the f10 image above. It more clearly shows the full extent of the jet. | Scope: 8" LX 200 SCT |
