85mm focal length; reduction factor of about 0.5X; depending on spacing; 0.5x focal reducer effectively halves the focal length of a telescope; enabling lower magnification; a wider field of view; and shorter exposure times for astrophotography
2 lenses for better correction: cemented together and coated; black anodized aluminum housing
Mounting threads: 1.25inch filter thread "28.5x0.75MM" on both sides: Threads into eyepieces; camera adapters; and other accessories with standard 1.25inch threads; and can be stacked with additional 1.25inch threaded accessories
It not only increases the magnification; the image will be clearer than the average increase in magnification up to 15 times the image clarity
Essentially triple the power of any 1.25 inch telescope eyepiece with the universal Barlow Lens; suitable for high contrast; high power applications in any telescope
