1. Introduction

My favorite star atlas had been "Norton's Star Atlas (Epoch 1950)". I liked its large scale (3.2mm/degree), wide field covering and small distortion. I can not find favorite star atlases in epoch 2000. I don't like "Norton's 2000" because the maps can not be opened flatly. I am using "Wil Tirion's Bright Star Atlas" but its scale is rather small (2.7mm/degree) and distortion is not small.

I decided to make a new star atlas for myself. I intended to make a better star atlas than existing star atlases. Following features will be realized.

(1) Large scale
(2) Wide coverage with small distortion
(3) Large overlap

Amateur astronomers will welcome the new star atlas.

Taki's Star Atlas was introduced in June 2005 issue of Sky & Telescope. ("Books & Beyond," Sky & Telescope, June 2005, p.103)

Mr. Mauro Amparore in Italy kindly added constellation lines and other improvements to the charts. I uploaded the improved version with the file names starting with "c". Mauro, thank you for your contribution!

Dr. Sky C Murphy, a member of Mornington Peninsula Astronomical Society and Astronomical Society of Victoria in Melbourne, Australia, kindly added constellation lines based on H. A. Rey's popular book, "The Stars, A New Way to See Them." He also added popular star names. I uploaded this version with file names starting with "cr". I appreciate his effort.

I will welcome your comments or suggestions for improvement. Please send e-mail to Toshimi Taki.

5. Idea for Handy Map

(1) Prepare a sheet of cardboard with a little larger size than A4.
(2) Fold a pair of a northern map and a southern map in two.
(3) Glue the lower half of the northern map on the cardboard.
(4) Glue the upper half of the southern map on the opposite side of the cardboard.

An example of the completed handy maps is shown in the photographs below.
