Do you want both hemispheres (360 degrees) or just what is above the horizon at a given date and time (180 degrees) like the monthly sky charts in Sky and Telescope? Cartes du Ciel will make a chart showing a complete horizon view, but the detail is limited to what will show on a computer screen at once. For a poster size map you might need to plot it by hand. I think the maps in Sky and Telescope are stereographic projections, which make a good looking chart with less distortion at the horizon than some other projections. One possibility is to find a program that will plot a detailed all-sky chart (I don't know which one) and output it to a .pdf file. The current Adobe Reader will let you print enlarged sections of a .pdf file that you can paste together to make a poster. Bud
