Deep-Sky Atlas - 1st release

This is a first release of Deep-Sky atlas. Click here for a newer and more detailed second release of "Deep-Sky Hunter" star atlas, which covers entire sky (designed for A3).

I created this atlas in 2007 as a field aid for observing deep sky objects. It has approximately same scale as Sky Atlas 2000, features stars up to 9.5th magnitude, and was designed for colour or greyscale printing on A4 pages. Since only deep sky objects down to 12.5th to 13.5th magnitude are plotted - it is possible to find almost every DSO featured in this atlas using a moderate telescope (over 8 inch) under dark skies.

Each of 80 charts covers 20x30 degrees of sky, and it is limited to declination of -58º south. The atlas is optimized for viewing under a red flashlight. Source charts were generated in "TheSky 5" program (Software Bisque ® all rights reserved) and converted to PDF (vector graphics). All labels, notes and index maps were manually revised.

Features:

  • Stars down to 9.5th magnitude
  • Labeled DSO down to 12.5th magnitude
  • Marked double stars up to 8.5th magnitude
  • Ccommon names of deep sky objects and stars
  • Index charts, constellation index, and "next-page" direction marks
  • Constellation lines and borders
  • Shaded Milky Way, RA/DEC grid, ecliptic, constellation lines

Notes:

Stars down to 9.5th magnitude from Tycho, Hipparcos and Guide Star catalogs are plotted and labeled with common names, Bayer and Flamsteed designations.
For select double stars - separation in arc-seconds is listed. Labels of deep sky objects (common names and catalog numbers) are plotted down to 12th magnitude, while fainter DSO (down to 12.5-13.5th magnitude) are displayed without a label - this may give a hint whether a particular object is reachable. The atlas is less suitable for southern hemisphere observers, since it plots the sky only down to declination of -58º (south). It covers whole sky for observers living from 32°N and higher.
To print the atlas Adobe Acrobat reader is required.

Instructions for printing:

For best results print the atlas as explained in the following diagram, at 600dpi resolution (at least), preferably in color, on A4 paper, with "reduce to printer margins" option checked.
