When using a DSLR and a refractor between f\/5.5 to f\/6.5 the field is flattened across the entire sensor. When using small chips like popular 4\/3rd's or 1\" size sensors, refractors up to f\/7.5 will not experience any change in focal length.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e Requiring a standard 55mm of back focus, this Starfield 1X flattener is perfect for any DSLR imager and is well suited for APS-C and smaller sensors. No additional extension rings are required.  The standard clear aperture of 38 mm offers no vignetting with APS-C and smaller sensors. A 44 mm clear aperture is produced when the optional 48mm T-Ring adapter is used. Your imaging sessions will benefit with a flat field while maintaining your telescopes focal length. \u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv\u003e\u003cspan\u003eA standard 42 mm T-Ring is required.
