Reseña del editor 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.
