    Default Pentax Xl eyepieces



    Hi, does anyone have experienes to share on the 5.2 and 10.5 Pentax XL eyepieces? I have a 40 XL and love the long eye relief and sharp image all the way to the field stop. The 1.5 degree FOV doesn't hurt either. Can I expect similar performans and comfort in the shorter FL eyepieces? Thanks, Pete

    i have only ever heard great stuff
    concerning pentax glass,so i would assume
    that those you have listed will be no different.
    however,i'm sure bob327 will give you a definite
    answer when he logs on,as he has owned pentax ep's,
    and still may do.value his opinion,he knows.
    clear skies,

    Appreciate the input guys, went ahead and ordered both. If/when the sky ever clears I'll post my impressions with the 14" Dob and the 5" achro.

    Finally a night of clear skies and fairly steady seeing. Tried out the pentax XL 10.5 and 5.2 on a variety of targets last night using a 4.7" f1000 refractor. Mars was very well seen with significant areas of dark surface detail in good moments of seeing particularly in the 5.2. Jupiter was easily seen with multiple bands although the seeing at it's low elevation wasn't great. The moon was spectacular along the terminator with a wealth of apparent detail and no color fringing at all.
    Viewing was crisp and without distortion in both eyepieces on stellar DSO's like M41, large numbers of stars resolved with more winking in and out of view as seeing conditions changed. The FOV of the 5.2 just allows the cluster to be seen in it's totality, the 10.2 includes a generous area framing the target. Both eyepieces proved to be very comfortable to use with glasses and allowed the entire FOV to be seen without having to move your eye around at all. All in all I am very pleased with both eyepieces and found them to be as good and more comfortable to use than my Naglers. Seeing did not support barlowing the 5.2 so that will have to wait for another night.

    These along with the Televue Naglers are both considered the "CADILLAC" eyepieces. Complete Sets of the Pentax go for several thousands of dollars used.
