The Rand McNally "Glow-in-the-Dark Star Finder with Zodiac Dial" has both good and bad features. On the positive side, the Star Finder is large and easily readable. On the negative side, it contains text that says, "...the ecliptic...is divided into twelve months," and presents a "Zodiac Dial" assigning a constellation to each month. This is wrong for two reasons: (1) The zodiacal constellations are not actually in synch with the calendar months as depicted on the Zodiac Dial. For example, according to the Zodiac Dial, the sun is in Scorpius in December. In fact, the sun is in Scorpius only for a week at the end of November. (2) The sun actually appears in 13 constellations as it moves along the ecliptic (not just the 12 that astrology is based on). The zodiacal constellation of Ophiuchus has been left out. Finally, there is a table showing where to find the planets for a period of six years. Unfortunately, the Star Finder that I looked at had a copyright date of 1995, and gave the planets' positions for 1995 to 2000. The tables for the years prior to the current year are useless. It would be good if Rand McNally would update the planet tables every year or two so that the tables would be useful for a longer time after the Star Finder is purchased. In short, if all you need is a star finder, this one will work just fine. But, pay no attention to the incorrect zodiac dial.
