For Sale: A mint condition copy of this excellent star atlas. Never used in the field. I have two, and can't wear out my field copy. I have penciled in the constellations (can be erased if found objectionable). I find this to be an outstanding star charting atlas. It has five levels of magnification, with the most detailed level to 11th magnitude. This level only covers the most dense areas of the night sky. The third level (level C) covers the whole sky, Noth and South, with stars to 9th mag. For $50, you can have this fine star chart delivered to your door, CONUS.
