Firefly Planisphere: Latitude 42 Degrees North
(about the previous edition) This is a beautiful instrument the size of a tea tray, with detailed star maps..., right ascension and declination scales, and horizons for latitudes of 40, 50 and 60'... Beginners can find their way around the sky, while those with a deeper interest can use the tables of coordinates of interesting objects...... Very high quality...an excellent guide to the fundamentals of astronomical observation. (Royal Astronomical Society2004-01-00)
