I'm gonna use Newton 76/700. It is what it is for now. I don't like 4mm eyepiece, 'cause it's impossible to focus properly either with Barlow lens or not, so I wanna gather up some good kit: an eyepiece + BL (I want to get a clear picture). Please give me some advice : ) Levenhuk Customer Service:
By using 4 mm eyepiece you get 175x and together with 2x BL it's up to 350x, which goes beyond the highest practical power of your telescope( 150x). You can find an appropriate eyepiece by using this formula: F/f, where F is the focal length of the telescope, and f is the focal lenght of the eyepiece. Consequently it's recommended to use 4.7 mm or 5 mm eyepiece.
"This eyepiece" is the 6.3 one? Levenhuk Customer Service:
Yes, Levenhuk Kellner 6.3 mm Eyepiece
I've bought Levenhuk Skyline PRO 80 MAK telescope. There are 3.6mm and 17 mm eyepieces in the kit. Please suggest me an eyepiece with high-power magnification within the possibilities of the telescope 'cause 3.6 is obviously beyond. Levenhuk Customer Service:
Levenhuk Kellner 6.3 mm Eyepiece is pretty good to get the highest practical power of 160x.

I wanna buy some stuff from your store. I'd like to get higher magnification during planetary observations, and at the same time not loosing the quality. Please suggest a couple of eyepieces or Barlow lens. I own Meade NG60-SM. put it another way. i wanna magnify images many times not loosing the quality ( 9mm is not enough) . thanks. Levenhuk Customer Service:
The highest practical power, i.e. magnification without quality loss, of the Meade NG60-SM model is 120x. Levenhuk Kellner 6.3 mm is the best possible choice.
I was amazed at first about the high quality and small exit pupil, but then I get it - it's because of the achromatic lenses! Levenhuk Customer Service:
Thank you for your feedback!
