Bresser 80/400 Refractor Automatik GoTo

Barlow lens 2x, 1.25 inch, achromatic and multicoated, metal housing with screw-on mount.

• Fits into any 1.25 inch eyepiece holder. Each magnification multiplied by 2: a 10 mm eyepiece gives 130x at 650 mm, 150x at 750 mm.
• For what: Moon and planets with the 10 mm eyepiece at 650 to 1000 mm; the 25 mm eyepiece gives 52x to 80x magnification.
• Do not combine with a 6 mm eyepiece or shorter at 650 mm or longer: 217x or more is usually too much.
• A filter in the eyepiece remains operational. Four times less light: enough for the moon and planets, not for nebulas.

Moon filter with approximately 30% transmission and 1.25 inch filter thread, for telescopes up to about 150 mm opening.

• Fits: screws into the filter thread at the bottom of each 1.25 inch eyepiece. Not for 2 inch eyepieces; for those there is the 2 inch version of 25% or 13%.
• For what: the moon, and Venus and Jupiter if they are too bright. Blocks about 70% of the light, no color fringing.
• At an opening of 70 to 114 mm for this filter, at 130 to 150 mm for the 25% version, and from 200 mm for the 13% version.
• Clear, homogeneous glass in a metal frame. Never use in the sun.
