There are numerous images of Messier, NGC, IC, and other catalogue objects scattered around the image pages, taken with various instruments and interspersed with text. So these pages bring the NGC objects together with only a brief description. They are still shown on the image pages, so if you want to know more about where and when they were taken, just visit the appropriate page by clicking the link.
The listing is split into pages numbered in blocksof 1000. Not that I ever expect to come anywhere near filling the pages - it just makes viewing quicker!
Where I have more than one image of an object, I have used what I consider to be the best of them.
