    Default Older series 4000 vs 5000 series Meade eyepieces



    Optical Test
    Eyepieces



    Scope : 6” f/9 Type : APO Refractor


    Eyepiece in mm : 20mm

    Eyepiece design : Plossl

    Number of Elements : Series 4000 has 4. Series 5000 has 5.

    Country of manufacture : Japan (older series 4000) & China (series 5000)

    Multi coated : [ ]

    Fully multi coated : [ X ]

    Filter Used : No

    This optics test was done on the older Meade series 4000 20mm Plossl (made in Japan), and the new series 5000 20mm Plossl (made in China). The scope used in this test was a Meade 152mm f/9 ED LX650.

    The coatings on both eyepieces are fully multi coated and have a nice dark deep bluish-green color. I notice no flaw in the coatings on the eyepieces used in this testing. Both are well made, but the Japanese made series 4000 looks much nicer. The feel of the series 4000 seems much more solid than the larger sized Chinese made series 5000.

    First test subject was M8, also known as the Lagoon Nebula. The on axis sharpness and contrast was easily seen to favor the older series 4000. I could see more nebula in the outer regions with the series 4000 20mm than with the series 5000 20mm. This could be due to the following:

    1) The use of higher index glass,
    2) A better glass surface polishing process.
    3) Better over all coatings of all glass elements.
    Contrast plays the most important part in showing more fine detail in the faint filamentary structures on the outer regions of Nebulas. The older Japan made series 4000 is the winner in this test.

    For off-axis sharpness, the older Japan made series 4000 shows stars in perfect focus out to the edges. The series 5000 was only good out to 85%. Seeing that I was using an f/9 focal ratio scope, the off-axis sharpness of the series 5000 would not be good in a fast scope. I will be testing the 20mm series 5000 in a 16” f/4.5 to see how bad the off-axis really is.
    I will like to state that I have looked through two other series 5000 20mm Plossl eyepieces. These other two 20mm eyepieces were much better optically then the one presented in this short write up. I my conclusion of this test. If you can find an older series 4000 Japan made 20mm and you have a fast (or slow) focal ratio scope, I highly recommend the older series 4000 Plossl due to the better contrast and off-axis sharpness. The reason I do not recommend the 20mm series 5000 is due to the optical performance I had seen between the 20mm I tested and two other 20mm series 5000's which were better in off-axis sharpness to the one I tested. I have viewed through many older Japan made series 4000 20mm eyepieces, and they all had very good contrast and off-axis sharpness.

    Thanks for the review. I assumed the older EP's were most likely better, Im glad you took the time to prove it.

    Interesting stuff. Pity you didn't have the series 3000 Plossl to try against them too, as I have heard that they are the real gems of the Meade back catalogue.

    I was an optics tester back in the late 80's to mid 90's. I tested optics for many big named companies. I did do testings on the 3000 series, and yes they are nice eyepieces. The coatings on the 4000 series are better though, as the 4000 series did not have the ghosting problems that some of eyepieces in the 3000 series line up did. The real gem in the 4000 series was the 14mm UWA made in Japan. The newer 5000 series 14mm UWA can not even compete with the older Japan made ones.

    Is this different than the 4000 super plossls? Have you looked thru the 5000 HD 60s?

    Super Plossl is just a name Meade gave to the series. The best Plossl I've ever looked through are the ones by Tele Vue. Tele Vue Plossl's have better glass surface polishing and uses higher index glass than most. Next to Zeiss, Tele Vue uses some the best optical coatings on the market.

    As to the Meade HD series, I've not looked through any yet.

    Good info and thanks for taking the time to post your findings. I was looking into a Meade 5000 EP although I'll think it over again. Might go with a 4000.

    I use the 8.8mm for class I through class III globular clusters. It is a large eyepiece, but it has very good on axis sharpness, and very good contrast. The only Japan made 4000 series I still use are the following :
    8.8mm UWA
    14mm UWA
