DEREK HASELDEN'S ASTRONOMICAL LISTS AND TABLES, PAGE 3
Deep Sky Objects
Updated 1st January 2004
This page is one of a series of three composed almost entirely of data in tabulated form. It is the result of several years of occasionally, but progressively recording information gleaned from books, magazines and the internet. Almost any astronomical book you encounter these days will have some numerical data within its pages in some form or another. So, when I started writing a series of astronomy notes about 8 years ago I included a section which listed useful and interesting astronomical information.
Since starting that project it has been necessary to revise, update and expand some of those tables to reflect new data. For example, recent discoveries of additional moon's orbiting the gas giant planets has prompted me to revise those tables, almost tripling their size in the process. As and when I've found time new tables have sprung up or old ones combined to make up the set of tables on this page. Doubtless there will be others to follow!
The other two pages in this series are Astronomical Tables 1 - Solar System Objects, Miscellaneous and Astronomical Tables 2 - Stars.
I hope that you are able to make use of this page and the data within, you may well see something you've not come across before. Perhaps you'll even think of other information that would be useful! Furthermore, should you find any errors or know of more up to date figures please do let me know. Whatever the case, please feel free to comment or make suggestions. An e-mail link/button appears at the bottom of this page.
This page was written by Derek Haselden and is the result of many, many hours of digging through books, magazines, journals and other reading matter - and then typing and assembling it into the order you see below. As such I cannot claim it to be 'original' but I have put great deal a lot of work into this and while I am more than happy for others to make use of this page, the only condition I would make is that you ask for permission first. Otherwise, please feel free to edit, extract, uproot and quote as you see fit, but please, do not distort or mangle it too much. Feel free to copy, distribute, paraphrase, et cetera, et cetera, but do me the honour of quoting the writer and/or include a link to me.
Thanks.

TABLE 30. THE MESSIER OBJECTS
The data below lists the 109 objects that the French Astronomer Charles Messier (1730-1817) catalogued. The Messier list was first published in 1774 with later revisions in 1780 and 1781. Note that there are 110 objects listed but that one of them is in fact a duplicate.

TABLE 31. 108 BRIGHT DEEP SKY OBJECTS
The following list details over 100 deep-sky objects in order of decreasing magnitude. I've no idea if such a list has been compiled before but some may find it of interest; it does give some idea of several objects that are theoretically within the reach of the naked eye and should be visible even with just a pair of binoculars. Deep-sky objects are often thought to be the province of powerful telescopes - this list indicates otherwise.

There are a little over of 100 of these cluster dotted about the sky, a great many of them can be found in Ophiuchus and Scorpius. This list catalogues some 70 of these objects, all of which should be within the range of modest instruments.

TABLE 34. 56 PLANETARY NEBULAE
A more challenging list of objects owing to the great variety of magnitudes and sizes. In some instances the magnitude of the nebula itself can be quite misleading, for example the Helix Nebula, first on the list, has a low surface brightness owing to is great size - paradoxically making it a bright nebula, but one that is quite difficult to observe. For brightness, try M27, the Dumbbell Nebula - a much easier target!

TABLE 36. 7 DARK NEBULAE
A rather short list this one, comprised mainly of a few of the dark nebulae catalogued by E. E. Barnard (1857-1923) and published in his A Photographic Atlas of Selected Regions of the Milky Way in 1927. These are some of the most notable 'holes' on the sky, distinct areas where there are few stars in comparison to the immediate area surrounding them. They are in fact dust clouds obscuring most of the stars behind and appear as an unusually dark patch. For obvious reasons no magnitude is quoted for these objects. Apart from the Coal Sack the remainder listed below are largely the province of telescopes and binoculars - and a very dark observing site! Either that or photographs will show these objects.
A notable exception being the Cygnus Rift, a great dark band appearing in the Milky Way alongside the 'Northern Cross' or 'Swan' asterism of Cygnus. Once spotted it becomes obvious, and it covers a huge area of sky stretching roughly from Deneb (alpha Cygni) to the small constellation of Scutum.
