Assembling the NGC was a challenge, as Dreyer had to deal with many contradictory and unclear reports made with a variety of telescopes with apertures ranging from 2 to 72 inches. While he did check some himself, the sheer number of objects meant Dreyer had to accept them as published by others for the purpose of his compilation.
Using the label serial number, NGC will reveal a coin's date, denomination, grade, photo (if any), and pricing and Census info. NGC Coin Explorer lists key info about many coin issues, such as mintages and values. [15] The NGC Census reports how many examples of each issue NGC has certified by grade, which helps determine relative rarity.
This is a list of links to New General Catalogue objects. It mostly exist to document which articles exist (they are presumed notable per WP:NASTRO) and to ensure redirects exist if they are not primarily known by their NGC number.
This catalogue originated the usage of letters and catalogue numbers as identifiers. The capital "H" followed with the catalogue entry number represented the item. [4] In 1864, the CN was expanded into the General Catalogue of Nebulae and Clusters of Stars (GC) by John Herschel (William's son). [5] The GC contained 5,079 entries.

The letters, received by several residents in January, contain what looks like a $199 check that purports to be a “Registration Fee Voucher” from “County Deed Records.”
The following is a list of NGC objects, that is objects listed in the New General Catalogue (NGC). It is one of the largest comprehensive astronomical catalogues for deep sky objects such as star clusters, nebulae, and galaxies.
