DescriptionHere is a picture of a Galaxy Cluster known as Markarian's Chain. This is not the entire cluster, but includes a section centered around M86 (The large galaxy in the center of the picture). Markarian's Chain is part of the Virgo cluster of galaxies in the constellation of Virgo. It is named after Armenian astrophysicist, B. E. Markarian, who discovered their common motion in the early 1960s. The galaxies in this picture include M86 (in the center), then counter clockwise from the left side of the image are NGC4438, NGC4435, NGC4402, M84, NGC4387, NFC4388, NGC 4413, and NGC4425.

DescriptionThe Western Veil, NGC 6960, commonly named The Witch's Broom, is part of the Veil Nebula, which is also known as the Cygnus Loop. The Veil nebula is located in the constellation Cygnus, about 1400 light-years from Earth Although this image was taken with Ha and OIII narrow band filters, it is a good presentation of how the nebula looks if red, green and blue filters were used. This is possible because the band width of the OIII filter is about half way between green and blue. Ha is mapped to red and OIII to green and blue.
