  • The Astrophotography Planner, 2020-2021 Edition, Charles Bracken


    The Astrophotography Planner

    This started out as my personal image ‘almanac,’ to help me plan when I should image specific objects.  I built upon that to create a full book with maps and complete details for the most popular imaging targets. 

    Producing great deep-sky images requires many hours of exposure time. Knowing when an object is optimally placed in the sky is critical to gathering the best data. This book features charts and maps for 76 of the best deep-sky objects visible from the northern hemisphere. The charts show how many quality imaging hours you can expect for each on any given date, as well as where it will be positioned. Maps are provided to help you decide how to frame each object, and field of view templates are provided for common sensors and focal lengths. Detailed information about the moon is included for 2019 and 2020.

    In short, The Astrophotography Planner will help you make the most of every clear night to produce the best deep-sky images possible.

  • The Astrophotography Sky Atlas, Charles Bracken


    Upgrade from the star charts you’re using to maps that actually focus on objects you’ll want to image. The Astrophotography Sky Atlas plots over 2000 deep-sky objects in their correct size and shape, including many nebulae not shown in other atlases. Stars are shown down to magnitude 9.0.  The entire sky is covered in 70 full-color charts.

    A tabular index contains important details on each object, including a description, the best time of year to capture it, and the required field of view.

    What’s shown:

    • 416 emission nebulae and supernova remnants, including the complete Sharpless (Sh2) and RCW catalogs.
    • 171 reflection nebulae, including the complete van den Bergh (vdB) catalog.
    • 146 planetary nebulae, including the complete Abell catalog
    • 52 dark nebulae and molecular clouds
    • 792 galaxies (larger than 3 arcminutes)
    • 38 galaxy groups from the Abell and Hickson catalogs
    • 108 globular clusters (larger than 5 arcminutes)
    • 309 open clusters (larger than 5 arcminutes)

    To keep the focus on imaging, sparse open clusters and galaxies smaller than 3 arcminutes (unless part of a group) were left off the maps.

    With information on nearly every possible photographic object in the night sky, The Astrophotography Sky Atlas will help you choose your targets and plan your imaging.

  • The Deep-Sky Imaging Primer, Second Edition, Charles Bracken


    This is the book that we (OSI and Astrodon staff) highly recommend to anyone interested in Astrophotography! We refer to it daily when handling customer questions. It is our “Astrophotography Bible”. This is the one to get!
