This is a great little atlas packed to the gills with information and charts. I have another copy of this star atlas and is great to use at the telescope. I ordered a second copy which came on time and in excellent condition from Amazon, but it seems the publisher, Springer, made an error in the atlas. Although the Key to the Star Atlas is listed in the Table of Contents for page 164, it is missing in the back. There is no page 164. I will either contact Amazon for a return or contact Springer and see what they want to do.
