Starboosa Multi-Coated 0.5X Telescope Focal Reducer for 1.25 Inch Telescope Eyepieces

Feature:
FMC multi-coated optical glass is provided to increase the light transmittance; more bright and clear image.
It can reduce the focal length of the telescope to 0.5 to 0.8 times the original focal length.
Suitable for astrophotography, reducing exposure time; providing lower magnification and wider field of view.
Video field of view doubled; recording a large portion of the moon’s surface with a webcam.
Standard 1.25-inch interface; fits any 1.25-inch astronomical telescope eyepiece.
Connecting thread: filter thread on both sides 1.25″ (M 28.5 x 0.75)

Fits all standard 1.25-inch eyepieces; reduces the focal length of the telescope by half; increases the field of view.
Multi-coated optical glass makes the imaging clearer and sharper; the frame is made of aluminum alloy and the surface is anodized to prevent corrosion.
Simple installation; screw the reducer lens into the 1.25 ” telescope eyepieces ; effectively reducing the focal length of the telescope and increasing the viewing field.
Universal for 1.25″ eyepiece and filters;thread on both sides for using with filters;It can be superimposed with other 1.25″ filters while connecting eyepieces.
Suitable for telescopes with longer focal lengths; improves the field of view of the eyepiece, from narrow to wide.
