A non-focal reducing Field Flattener which gives improved results for photography with triplet and doublet refractor telescopes of between F5.5 and approximately F6.25 focal ratio.
- Gives improved results with refractors with focal lengths up to F6.5, and with smaller chips, up to F7.5 without changing the focal length of the telescope. - Integral T-Ring adapter thread. - Requires back-focus of 55mm to CCD Chip. - For DSLRs a standard T-Thread adapter of approx. 10mm thickness is required. - The standard 2" OD barrel will fit any 2" format telescope like an eyepiece. - The base of the 2" OD barrel is threaded for 2" filters. - CNC machined body with gloss black anodized finish. - Includes a CNC machined T-threaded end-cap to protect against dust on the rear lens element which is more exposed than the front element. A plastic dust cap is included for the 2" OD front barrel.
