A twist of the zoom eyepiece housing changes focal length from 21 mm to 7 mm providing a variety of viewing magnification powers; excellent contrast and sharpness making the zoom also of interest for planetary observing
Exceptionally long 16 mm to 33 mm eye relief range allows eyeglass wearers to enjoy the entire view while still wearing their corrective lenses without vignetting; the Zoom eyepiece lets you change magnification power without physically changing eyepieces
Apparent field of view is 30 degree at 21 mm and 43 degree at 7 mm; rubber traction ring ensures a good grip; the 1.25 inch barrel is threaded for filters; actual magnification range will depend on the focal length of your telescope
Designed primarily for planetary observation "Moon; Jupiter; Mars and Saturn and more" but great for deep sky objects too; comfortable eye relief averaging 16mm across the series; threaded for standard 1.25 inch astronomy filters
Wide 58 degree Field of View "FOV" in 2.5mm to 25mm focal lengths; 1.25inch fully multicoated eyepieces give maximum detail and definition across the entire 58 degree field of view; each eyepiece has 5 lens elements in 3 groups
