Description
- MINIMIZES STAR DISTORTION IN ASTROPHOTOGRAPHY: When placed between your telescope and camera, the Explore Scientific field flattener counters the negative effects of field curvature, which causes stars to appear smeared as you move away from the center of the image.
- WORKS WITH FOCAL RATIOS OF F/5 TO F/7: This field flattener is designed specifically for astrophotography using refractor-type telescopes with focal ratios of f/5 to f/7 and requires 55mm (+/- 2mm) of spacing between the back of the device and the camera sensor.
- DESIGNED FOR A SECURE CONNECTION: The field flattener has a T-ring thread to easily attach a camera using a user-supplied T-ring.
- FULLY MULTI-COATED OPTICS: The optical glass is fully multi-coated to maximize light transmission and produce high-contrast astrophotographs of planets, nebulae, galaxies, star clusters and other night sky sights.
- USA SUPPORT: Based in Springdale, Arkansas, USA, you can always be assured of excellent customer service should you ever have an issue or question.
