This list summarizes all deep sky objects which are known or seriously assumed to have been discovered before William Herschel began his great Deep Sky survey in September, 1782.
We give the identification by name or catalog number, basic astronomical data, discovery data, and possible common names for each object. As these objects have all been detected with moderate equipment, they are all within the range of even modest modern amateur telescopes.
This project was partly inspired by a fruitful discussion with Glen Cozens. Data are partly based on the original Messier data, collected by Guy McArthur and updated by the authors with the help of Bill Arnett.
This list is arranged to 3 lines per object. Also available as 1-line and 2-lines per object lists.
This list is sorted by catalog number/Name. Also available: ordered by Right Ascension, ordered by Declination, ordered by Constellation, ordered.by Discovery Date.
