The EVAC Hickson 100 Observing Program
Compact Galaxy Groups have been of interest to astronomers ever since the discovery of Stephan's Quintet (Hickson 92) in 1877. The Hickson Compact Galaxy Groups were compiled by Paul Hickson and published in his Atlas of Compact Groups of Galaxies in 1994. They represent the brightest groups visible to northern observers and this makes them ideal targets for amateur astronomers.
The EVAC Hickson 100 represents those groups with a minimum of four galaxy members. Using the log form available below, indicate the number of galaxies you can observe within each group.
To download this observing program for use in the following popular astronomy software applications, simply right-click the appropriate button and select Save Target As... from the menu. Navigate to the folder of your choice and click OK.
