# Messier objects not included in other Celestia catalogs
# gathered by Selden Ball, 13 August 2003
#
# The initial RA,Dec and Distance values were from SEDS articles
# See  http://www.seds.org/
#
# The RA, Dec and radius values specified here are those needed to place
# the images in the correct places. They are not the nominal locations
# of Messier's objects themselves.
# 
# Initial model orientation determined using 
# Grant Hutchison's DSC spreadsheet
#
# Many of the images were positioned by using background images
# downloaded from http://virtualsky.org/
#
# The images provided with this catalog are intentionally
# low resolution. Also, they are not necessarily positioned
# at precisely the right locations, although the errors are usually
# much less than a minute of arc.
#
# It is expected that fans of Messier's objects will obtain
# high resolution and accurately positioned models from other sources.
