Hickson cluster 96 Hickson cluster 96 taken at the Oregon Star Party 8/14/04. There are four galaxies: a. NGC 7674 mag. 13.5, b. NGC 7675 mag. 14.5, c. MCG +1-59-81 mag. 15.7, and d. PGC 1507 mag 16.6. NGC 7674 is a Sb spiral galaxy type showing two arms and NGC 7675 is a E0 elliptical galaxy type. MGC +1-59-81 is an E1 elliptical galaxy type. PGC 1507 is too faint to determine the type. The total integration time was 7.5 minutes. Apparent sizes of these galaxies are very small. Here the image field is less than 0.1 degrees.

Hickson cluster 93 taken at the Oregon Star Party 8/13/04 Hickson cluster 93 taken at the Oregon Star Party 8/13/04. There are four galaxies in this cluster: a. NGC 7550 mag.12.6,b. NGC 7549 mag. 3.2, c. NGC 7547 mag 13.9, d. CGCG 454-15 mag. 15.3. NGC 7549 has a very distorted nucleus. The field of view is less 0.2 degrees. The image was the result of five stacked three-minute images. Photo by Harry Colvin Click for a larger version |
Hickson cluster 92 taken at the Oregon Star Party 8/13/04 Hickson cluster 92 taken at the Oregon Star Party 8/13/04.Of the five galaxies in this cluster, NGC 7318 A and NGC 7318 B seem to have interaction: a. NGC 7320 mag.12.5, b. NGC 7318 B mag. 13.2, c. NGC 7319 mag. 13.3, d. NGC 7318 A mag. 13.6, and e. NGC 7317 mag. 14.0. The field of view of this cluster is less than 0.1 degrees. The image is made of five raw three minute images that have been stacked and processed. The total integration time was 7.5 minutes. Photo by Harry Colvin. Click for a larger version |

NGC 426 mag. 12.8, b. NGC 429 mag. 13.4, c. NGC 430 mag 12.5. Photo by Harrry Colivn. Click for a larger version |
The Great Hercules Cluster, M-13 The Great Hercules Cluster, M-13, the showpiece globular clusterof the northern hemisphere. 25,000 light-years from earth, with an approximate diameter of 160 light-years, it is estimated that it contains more than a million stars.

M-51, the Whirlpool galaxy M-51, the Whirlpool galaxy, 37 million light years away. Estimates of its diameter range up to 100,000 light-years. Note the nuclear bulge, arched lanes of stars and glowing interstellar clouds, which appear as spiral arms, characteristic of a spiral galaxy. Click for a larger version |
