Pentax - XF 8.5 mm eyepiece

Pentax SMC eyepiece XF 8.5mm 60 °

The Japanese company PENTAX is a leading company in the field of optics. PENTAX also impresses in the astronomical sector with its apochromatic refractors and elegant high-end eyepieces.

Pentax XF 8.5 mm - binocular all-round eyepiece with 60 ° field of view

High contrast and very good sharpness in the field with a pleasant view.

Maximum sharpness and contrast

The use of special ED glasses (lanthanum), the blackening of the entire inner workings and all lens edges to avoid reflections also contribute to achieving this goal with the XF eyepieces, as does the SMC multi-coating, which is undoubtedly one of the best on the market.

Use of binocular approaches

The narrow construction of the eyepieces and above all the calm view with the comfortable eye relief make the XF eyepieces the perfect binocular eyepieces.

Adjustable rubber eyecup

Adjust the distance of the rubber eyecup perfectly. Regardless of whether you are observing with glasses or not, you will always have a pleasant insight. The position of the rubber eyecup locks into place, it can then no longer be adjusted.

Eye relief 18 mm

An important characteristic of a real all-round eyepiece is the eye relief. Even inexperienced observers will immediately get a good picture with the eyepiece. That is why we are happy to recommend these eyepieces for use in public observatories.

XF 8.5 mm and XF 12 mm are parfocal

It is particularly practical that the two XF eyepiece focal lengths from Pentax, the XF 8.5 mm and the XF 12 mm, are parfocal. You can change the eyepieces and do not need to readjust the focus.

Areas of application

The eyepieces can be used for all areas of application in amateur astronomy and nature observation, such as: binocular observation, planetary observation, deep sky observation, but also for nature observation, when it comes to maximum contrast with high-quality spotting scopes with 1 1/4 "connection.

Scope of delivery:

  • XF eyepiece 8.5 mm
  • Dust caps
  • Storage box

The Japanese company PENTAX is a leading company for optics. Also in the astronomy PENTAX delivers highest quality apochromatic refractors and perfect high end eyepieces.

Pentax XF 8.5 mm - binocular suitable all-round eyepiece with 60 ° apparent field of view

High contrast and a very good sharpness over the whole field combined with a comfortable insight.

A maximum of sharpness and contrast

The use of special ED-glass (Lanthanum) and the blackening of the complete inside and all lens edges to avoid reflection and also the SMC multicoating makes these eyepieces perfect in sharpness and contrast. So they are one of the best on the market.

Using with a binoviewer

The small diameter of the eyepieces and the calm inview with a comfortable eye relief makes this eyepieces perfect at the binoviewer.

Adjustable rubber eyeguard

You can adjust the rubber eyeguard exactly to the wanted distance. No matter of wearing eyeglasses or not, you always will have a pleasant invitation. The position of the eyeguard snaps in so it can not adjust.

Eye relief of 18 mm

One of the most important characteristics of an all-round eyepiece is the eye relief. With this eyepiece even untrained observers immediately will get a good image. So we highly recommend these eyepieces for public star observatories.

XF 8.5 mm and XF 12 mm are parfocal

Particularly useful is: Both XF eyepieces are parfocal. So you don't need refocus after changing.

Fields of application

This eyepieces you can use at all fields of application in the amateur astronomy and also at the terrestial observation, eg observing with the binoviewer, planetary observations, deep sky observation and terrestial observations. You will get the maximum possible contrast possible with high quality spotting scopes with 1 1/4 "eyepiece connection.
