About Astrophotography
DEEP SKY PHOTOGRAPHS were obtained with a variety of focal lengths, from very wide field Milky Way images with a DSLR lens to more narrow focused images with a 710mm focal length telescope. Specialized tracking mounts that follow the stars as the Earth rotates are used to allow capture of long exposures. Some exposures can be as long as 6 minutes but photographic sessions of a particular object will utilize hours to weeks of compiled data. A windy moment, a passing airplane, satellite, or cloud can ruin a single exposure. Therefore long exposures utilize adding hundreds of shorter captures. The cameras utilized include near infrared adapted DSLRs or specialized black and white astrophotography camera that make use of special "narrowband" filters to detect ionized hydrogen, oxygen, and sulfur. All images are computer processed with enhancement of the nuances in elemental colors.
SOLAR PHOTOGRAPHY also requires the use of a specialized tracking mount. The telescopes utilized are fitted with special multilayered lenses that block all but the very narrow spectrum of light produced by the sun's chromosphere. These filters are not the same as eclipse filters and are far more light restrictive. Again, never attempt to photograph or view the sun without specialized filters. Sun imaging uses a similar monochromatic astrophotography camera but images are captured at 10 millisec captures. Hundreds of images are gathered over 20-30 seconds and then computer sorted and "stacked" to achieve the best possible resolution.
