/* Repetition claim of time and location */ Your explanation above doesn't state the assumptions. What are the assumptions?
::::It is in the Astrometry section under distance of the Night Sky Template in the article. Distances of the nebula was done by using spectroscopy, which determines expansion velocity and comparing this with the nebula's angular expansion over time (using images over years[http://apod.nasa.gov/apod/ap011227.html]), using these we can calculate (within a margin) it's distance. The most precise measurement is around 6,300 light years, if you want, read the long technical explanation here.[http://adsabs.harvard.edu/abs/1973PASP...85..579T]. --[[User:BMcP|BMcP]] 14:03, 20 January 2010 (EST)
 
:::::BMcP, I'm asking a simple question and am hoping for a straightforward answer in your own words. If you don't know the answer, hopefully you're willing to look at it now with an open mind. Your explanation above doesn't state the assumptions. What are the assumptions?--[[User:Aschlafly|Andy Schlafly]] 14:15, 20 January 2010 (EST)
