I have given up now on any thoughts of using the 500mm f8 mirror lens 
for astro photography,and am exploring the standard telephoto lens of 
araound the 200-300mm range.To that end,and to get some idea as to what 
to expect..... if I may: I would like to ask Steve Lindsey if the image 
of the "North American Nebula" taken with the Nikor 300mm is the full 
frame or a selective enlargement as I am most impressed with what can 
be achieved with a relatively short telephoto lens.

Thanks folks for the replies,I think I sort of knew what the responses 
may have been :-)
