About The Nuts And Bolts Of Astrophotography Hardware
Astrophotography can be as complex as modern observatories or a simple as a cell phone behind a small scope. It is a very complex process, but made much easier with todays technology. There are dozens of mounts and optical tubes and cameras available to the amateur photographer with a wide range of costs. This book reveals One Way to view and photograph deep space objects. It identifies and describes the components of my personal backyard observatory. At the core of the system is the Celestron CGEM 11" EdgeHd. The telescope rides on the Celestron CGEM equatorial mount which is rated with a 40 lb capacity. This setup is similar to many mid range systems from different manufacturers, some better than others, which provide a range of features. I have laid out the hardware and software components which were necessary to be successful with a system of this type. The book lays out what I learned during development of this hobby. Included are basic descriptions of software tools, digital functions, and the processing steps required to get the best results from the raw images. The book includes a general overview of software functions and simple theory on cameras, OTA's, and mounts. Three mid-range cameras were used (Canon 6D DSLR, Celestron Nightscape 10100 Color CCD, SBIG STF8300M Monochrome CCD) with differing configurations and F-ratios of the telescope system. The scope can be configured as F10, F7, F2, or even F20 with Barlows. I have included more than 150 color images which show realistic examples of the capabilities and image quality the reader can expect with the different options on this system. Many of the photos could be better, but that's up to you. All the images are accompanied with comments and descriptions, basic attributes of the target, telescope and camera configuration, object location, and time of year availability. In Revision 2 many of the original images have been updated using a new camera (ZWO ASI2600MC) and telescope (14 inch EdgeHd). There are also improvements in the books text describing new technology and correcting oversights in the first version. See website ybvisions.
