Levenhuk Ra LER 3 mm is a short-focus eyepiece for planetary observations. It is a great accessory for Newtonian reflectors, catadioptrics, and apochromatic refractors. In general, it is a universal eyepiece compatible with a wide variety of optical systems. It features a good field of view and does not distort the rendered picture. The quality of the rendered image is high: there are no field aberrations or magnification chromatism.

The eyepiece's fully multi-coated optics are made of glass. The eye relief is sufficient to cover the entire field of view. The eyecup is made of rubber, and it can be folded or unfolded, if necessary. The body is made of aluminum.

The eyepiece can be installed on any telescope with a 1.25" focuser.

Features:

  • Multi-element fully multi-coated glass optics
  • Minimum chromatic aberration and spherical distortion, especially in the center of the field of view
  • Short focal length - ideal for observing planets
  • It does well with apochromatic refractors and high-aperture Newtonian reflectors.
  • Suitable for 1.25'' focusers

The kit includes:

  • Eyepiece
  • Protective caps – 2 pcs
  • Cleaning wipe

hi! Is it suitable for Sky-Watcher BK 1149EQ2? Is it in stock right now? Thank you! Levenhuk Customer Service:
Unfortunately, Levenhuk Ra LER 3 mm Eyepiece is not suitable for use with your telescope. It is better to use 4mm or 5 mm eyepiece to obtain the highest practical power of the instrument.

Ken Reese (2015-11-23 09:34): Positive
does this eyepiece fit Sky-Watcher BK 705AZ3? Levenhuk Customer Service:
Unfortunately, it doesn't. Using this eyepiece with your telescope, you will exceed the maximum useful magnification of the model. Images will get blurry.

Hi there, is this eyepiece suitable for iOptron Astroboy? Image quality will be alright? Maybe it's better to take a 4-mm one? Levenhuk Customer Service:
Levenhuk Ra LER 3 mm Eyepiece is suitable for your telescope. Together they will give you 120x, which is the maximum useful magnification of the instrument. Using a 4-mm eyepiece, you will be able to obtain 90x magnification. Both eyepieces do not affect the picture quality.

I have synta sky-watcher dob 8. According to my calculations, this eyepiece will allow me to achieve 400x magnification, ie the maximum useful magnification of this instument. But I'd like to hear your expert opinion first. So... is it suitable for my telescope? If yes, how will it affect image quality? thanks in advance! Levenhuk Customer Service:
Levenhuk Ra LER 6 mm Eyepiece is perfect to get the highest practical power of your instrument. But you should be aware that image looses in brightness and contrast when observing with extreme magnification like in your case.
