F/5.7 CCD Telecompressor Corrector for 160 f/7.5 StarFire EDF (160TCC)
Designed for: 160 mm f/7.5 StarFire EDF
Application: Digital imaging with CCD and DSLR Cameras. Also suitable for video and 35mm film cameras.
160TCC and ADATCC1 on SBIG STL11000
160TCC with Machined Aluminum Covers
This all-new design uses 3 elements of high-index glass to widen and flatten the field while increasing the photographic speed of the 160 f/7.5 StarFire EDF triplet refractor. It is designed to be used with a variety of cameras when matched to the appropriate adapter.
The 160EDF operating at f/5.7 (0.76x compression) is an ideal match for large format cameras. Extreme detail can be captured in very short time thanks to the fast focal ratio. This accessory is a must for H-alpha imaging where speed and resolution allows one to achieve incredible results. Wide-field images will be highly detailed, which allows the astro-imager to make very large prints without doing time-consuming mosaics. Even when enlarged to 30 inches, a single image will still have pinpoint stars across the entire frame. The 160 mm aperture is a giant step up, both in resolution and in light gathering over a 4" wide-field astrograph. The resolution of the 160 mm aperture is close to the limit of what the atmosphere will normally allow, and detail will rival that obtained with instruments twice this size.
Optimal performance depends on these factors:
When used with the recommended custom adapters, the image is fully illuminated with the recommended cameras. Only 2" round filters will present a tiny, insignificant amount of vignetting in the very corners.
