Deep-Sky Hunter Star Atlas
"Deep Sky hunter" is a printable deep sky atlas, designed for serious deep sky observers. It features stars down to 10.2m and DSO down to 14.0m.
This is my second release of a deep sky atlas. It is much more detailed, and covers entire sky with 101 portrait oriented pages. Manual post-editing was performed in order to ensure readable and non-cluttered charts. In addition, the atlas features 8 pages with 21 supplement "zoom" charts of galaxy clusters and densly populated areas, and indications of over 500 best objects (Messier, Caldwell, Herschel 400, SAC's best).
I designed this atlas with A3 page size in mind, however you may find it usable on A4 as well. In terms of scale and amount of detail - "DeepSky Hunter" falls between Sky Atlas 2000 and Uranometria 2000. Here you can see a comparison with other atlases.
Beginners and smaller telescope owners who find this atlas over cluttered - should check out my first release of deep-sky atlas (which is designed for A4).

Objects list and best DSO images:
A separate 35 page download of detailed deep sky objects list is also availabe, and it features list of ~7000 deep sky objects down to magnitude 14 from SAC database, which are roughly the same DSO which are plotted in this atlas. Objects without magnitude (i.e. dark nebulae) are also listed. The list is limited to declination -60°.
Objects are sorted by catalog number, starting with Messier list, then NGC, IC and so on. "Best" objects are marked in bold. Note that some inconsistencies might be present, due to different catalog designations which a specific object might have.
Additional download is a 20 page list of thumbnail images of ~700 best DSO. This list includes, among others, all objects which are indicated as "best DSO" in this atlas.
Instructions for printing:
For best results print this atlas on A3 pages, in black & white, portrait orientation, at 600 dpi resolution. Make sure "reduce to printer margins" option is checked. Cover should be the first page, then a spread of index1 and index2, followed by the rest. Or simply print the whole PDF document, starting with the cover page. If you choose to laminate the atlas - you may use a metal ring binder (see the following picture).
To print the atlas Adobe Acrobat reader is required.

Note: Some people reported that chart number 20 failed to print, probably due to high objects clutter. I found out that printing out PDF which containts only chart number 20 fixes this specific problem (here you can download such file).
Notes and copyright information:
Compared to many other atlases - this release is much less cluttered with information which is often useless for deep sky observers (variable stars, extremely faint DSO, etc). Also the labels do not overlap with other labels and stars, making it more readable.
Combined database of deep sky objects was used, including Messier, NGC, IC, PGC, UGC, MGC, PK, Barnard and numerous catalogs of star clusters. Common names of deep sky objects from various sources were used.
