Astromania 0.5X Telescope Focal Reducer 1.25 Inch for Astronomy Telescopes

Astromania 0.5X Telescope Focal Reducer 1.25 Inch for Astronomy Telescopes

• This telescope focal reducer 1.25 provides a versatile reduction range — at the standard spacing you get a full 0.5x focal reducer with 85mm focal length that is depending on spacing
• This telescope 0.5x focal reducer works beautifully as a reducer corrector lens that effectively halves the focal length of a telescope — turning an f/10 scope into roughly f/5 which dramatically brightens the image
• This focal reducer telescope enables lower magnification with a wider field of view and lets you fit the full moon large nebulae or open star clusters comfortably in the eyepiece for making the expanded field makes scanning the Milky Way a joy
• With 0.5x focal reducer 1.25 your camera or eyepiece collects more photons per second for cutting exposure time significantly; This focal reducer is a favorite among night-sky imagers who want crisp, bright results without long guiding sessions
• The fully coated two lenses design minimizes chromatic aberration and internal reflections for better correction; The rugged black anodized aluminum barrel protects the optics while keeping the reducer lightweight and durable for years of field use
• This focal reducer 1.25 inch tube barrel directly into eyepieces and other telescope accessories with standard 1.25 inch tube; 1.25 inch filter thread (28.5x0.75 mm) on both sides can combine it with additional threaded accessories like telescope filters
• Free transmission: 22.5mm lens aperture — the generous clear aperture ensures bright, unobstructed views even with wide-angle eyepieces; Can be used with additional spacers available separately to achieve further focal reduction
• Intended for use with longer focal ratio telescopes and eyepieces of narrow to moderately wide apparent fields of view; This telescope focal reducer performs better from f/8 like Refractors, Maksutovs and Schmidt-Cassegrains Telescopes
