David H. Levy's Guide to the Stars

Very good quality of the material and really big compared to other star trackers. The item was delivered well before time.

I bought this Star Finder for my grandchildren, so I wanted something that would not fall apart easily. I was very pleased to discover that both of the moveable parts are made of plastic, so if they are caught in the rain with it, it won't disintegrate. It was bought for Christmas, so they haven't tried it out yet, but from what I can tell, the operating instructions are both easily understood and found on the front. I like the white background for the star chart. The back of it has a lot of interesting tidbits of stellar data. I will buy this again.

Este planisferio es un buen producto para la observación astronómica

Very nice and very useful.. I will enjoy using with my telescope

This was my fault for not reading description fully, thought I was getting the 16" version used. Had I known this I would not have purchased it. Note: when using the other purchase options, do not assume the the the other options are for the exact same item!

This review is for the "Guide to the Stars" planispheres. Both have instructions on the front and a legend describing what you see. The ecliptic is explained and spring/summer and late winter tours are suggested. On the back is a tutorial on viewing in general with hints on preserving night vision and locating stars and constellations. There's a chart of meteor showers giving the time of year and constellation for the major ones and explaining what causes them. There are also celestial tidbits listing the 10 brightest stars, explaining star twinkle and more. Some binocular and small telescope objects are listed with hints on how to identify them. The larger planisphere lists more of them. The phases of the moon are explained, plus hints on using your hand to approximate distances. The visible planets are discussed along with suggested telescope power for viewing them. The large Guide to the Stars is huge, 16 inches across, and easy to read. The front includes the Greek letter designations for many stars. The publisher took advantage of the extra size and included more information and larger print than the smaller version. The smaller version of Guide to the Stars is 11 inches across and is also easy to read. It has the same tutorial as the larger one. I had initially bought the The Night Sky 30°-40° (Large; North Latitude) which I found very frustrating to use. Read my review of it for more comments.
