Other Renaix publications include the Deep Sky Naked Eye Field Guide and Whiteboard Astronomy for the Interactive Classroom.
The range of deep sky objects that avail themselves to the backyard observer in fall & early winter covers the entire spectrum. The dazzling array includes planetary nebulae, galaxies, globular clusters, open clusters and emission nebulae. They are widely distributed over 16 constellations.
On many fall & winter nights, armed with this Kindle field guide and a small telescope, an observer can choose between 33 deep sky objects at any given moment.
You don't need pristine skies to use this field guide. Ordinary backyard skies will work just fine. The beauty of the Reference Lines Methodâ„¢ used for mapping these objects is that in order to locate deep sky objects, you need only to locate the bright stars that outline the constellations. It is not necessary to mark out degrees in the sky or have a magnifying finder telescope.
Get multiple fall field guides for the price of one! This field guide can be used simultaneously on the free "Kindle for PC" application and on the Kindle. The 176 step-by-step maps were conceived, designed and formatted specifically for the Kindle. With this innovation, the amateur astronomer can now go paperless. The maps illuminate clearly on the Kindle with a white or red flashlight. When using the Kindle for PC, the user interface allows minimizing the glare from the laptop monitor to help preserve night vision. The iPhone and iPad versions are crisp and clear with virtually no glare.
Each deep sky object is displayed with a layered series of maps that progressively build a context of constellations and nearby stars. On the maps, the stars, constellations and deep sky objects are displayed in vivid white, and the sky is black.
Bright 4th magnitude reference stars serve as end points for each reference line. Deep sky objects are mapped in order as they traverse the sky throughout each night and throughout the fall season. Because reference line end-point stars are often repeated from one object to the next, after locating a deep sky object it is often easy to locate the next.
"Devon Ronsse proved to be a perfect fit for the task of editing the manuscript. He matched the demographic of a large sector of our intended audience. On the one hand, we are unveiling a method to locate deep sky objects that will be helpful to veteran stargazers. On the other hand, we wanted to be certain that anyone could download this field guide to a laptop or a Kindle and begin locating deep sky objects that same night. His fresh perspective, attention to detail and insistence on clarity proved immeasurably valuable." Renaix
