It is specifically designed for the Vixen R200SS Newtonian reflector, but is also suitable for other optics with similar specifications.\u003c\/p\u003e\n\u003cp\u003eThe optical design consists of 3 lenses in 3 groups. The corrector provides excellent correction of system-induced coma of parabolic mirrors and the resulting spherical aberration. The corrected field has a diameter of 44mm, making it also suitable for the 24 x 36mm format (full-frame DSLR\/CCD cameras). This guarantees razor-shape images across the entire field. The lens surfaces are coated with a cutting-edge 99.9% anti-reflective AS coating, which is also used for Vixen's flagship models.\u003c\/p\u003e\n\u003cp\u003eThis corrector will turn your Vixen R200SS reflector telescope into the perfect astrograph!\u003c\/p\u003e\n\u003cp\u003eFeatures:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePremium coma corrector for the R200SS Newton refelctor\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e3 lens systems in 3 groups, guarantees absolute colour purity and sharp stars to the edge of the field of view.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eImage illumination up to 44mm for full-frame images\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eReduces the focal length of the R200SS from 800mm to 760mm 1:3.8\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAlso suitable for visual observations with an eyepiece adapter\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eWeight: 175g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eWhats\u003c\/em\u003e\u003cem\u003e included:\u003c\/em\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cem\u003eComa corrector\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDust caps on front and back\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eColour: black\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFocal length (in mm): 760\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eMagnification: 0.95\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eMaterial: Aluminium\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eNet Weight total (incl. accessories) (g): 175\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eNet weight (without access.)
