This superb fully multi-coated double-element focal reducer takes advantage of the latest computer aided design techniques to achieve the highest standards of performance to dramatically increase the field of view (FOV) or imaging scale of your telescope regardless of brand or type.
The Antares 2 inch 0.5x focal reducer screws directly to the 2 inch filter threads found on eyepieces, camera nose-pieces, extension tubes, star diagonals etc.
The sheer versatility and performance of this new focal reducer can not be over emphasized! It fits virtually every 2 inch accessory (with filter thread) and effectively halves the focal length of any telescope it is used with (the exact effect of the reducer is dependent on its position in the optical system but an approximate halving of the focal length is typical of the result achieved when used with eyepieces and camera nose-pieces etc).
Made in Canada, this excellent optic has a CNC machined aluminium cell with a male 2 inch filter thread.
