In all dimensions alike, upward and downward,
throughout the universe,
there is no end.

Challenge your observing skills with this new observing guide of 99 Hickson DSS images and Megastar charts.

Megastar charts guide you through the universe for these deep sky objects: 50 galaxy trios, 50 galaxy groups and 50 Abell clusters.

This program of 250 galaxy groups and clusters is designed for detailed visual and/or CCD observation. For many, the challenge will be to see these galaxy clusters with their own eyes.

Many of the galaxy groups and clusters in this observing program are visually accessible with a 12.5-14" telescope under dark skies.
