Pentax eyepieces are widely considered to be among the best there are on the entire market. The zoom eyepiece is a comfortable and practical alternative to a set of fixed focal length eyepieces. Unfortunately many zoom eyepieces lack contrast and sharpness.
Pentax XF zoom eyepiece –
Excellent sharpness and contrast
– Pentax XF Zoom covers the most frequently used range of focal lengths for astronomical observation. The shortest focal length, 6.5mm, offers higher magnification than most zoom eyepieces will go.
• Ideal for binoviewers
– Many of the high quality zoom eyepieces on the market have a rather large diameter and are therefore not suitable for binoviewing. The Pentax XF has a very compact body and has a click-stop function which makes it perfectly suitable for binocular use.
• Bright image
– The Pentax SMC multicoating is one of the best on the market with superior transmission for a bright and clear image.
