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.

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.
