Designed for both visual observation and astrophotography, it reduces exposure times significantly while enhancing image brightness and contrast. Compatible with standard 1.25” eyepieces and equipped with threaded interfaces for easy integration with filters, this reducer is a must-have for millennial stargazers seeking wider, sharper, and faster celestial imaging. ## Description Lower magnification and wider field of view;shorter exposure times for astrophotography when you are using the SVBONY 1.25" 0.5x focal reducer It can reduce the telescope focal length to the 0.5 times of the original's;it’s also great for visual use for a bigger FOV and is indispensable when CCD imagingGreat tool for astrophotography telescope: Reduces exposure times and simplifies astrophotography;works great to photograph0.5x focal reducer Reduce 0.5x of the focal length for telescope eyepiece lensDouble the photographic image/video field Record a significantly larger portion of the lunar surface with web cameraStandard 1.25"interface Fits for any standard 1.25” telescope eyepiece lenFMC optical glass design 2 element optical design increases the light transmittance;the imaging is brighter and clearerCapture wider field of view The focal reducer is great for visual use for a bigger FOV and is indispensable when CCD imagingFully threaded to minimize reflections Blackened edges and blackened interior to reduce scattering of stray light and maximize contrast Fully metal for long time using Besides the male thread;it also has female thread at the rear end to fit filters etcSpecifications: Focal reducer: 0.5x Barrel size: 1.25"/31.7mm Thread interface: M28.5x0.6 thread at both ends Sleeve material: full metal aluminum alloy Lens coated: broadband coated Lens ,aterial: pure optical lens Total height: 20mmPackage includes: 1 x SVBONY 0.5x focal reducer Review: This focal reducer screws into the nose of an astrophotography camera or 1.25" eyepiece. For visual use, it turns a 20mm eyepiece into a 40mm, both decreasing the magnification and increasing the field of view. In astrophotography, the focal reducers does that, but it also reduces the size of stars on the sensor by half, meaning you can image faster with a wider field of view. For example, an f/10 camera/scope is reduced to f/5 will image roughly six times faster (if my math is correct) because the focal reducer concentrates more photons on each well in the sensor. This focal reducer works well and gives a nice view. I highly recommend it!
