Description
PF25MM Telescope Eyepiece 65 Degree Wide Angle Flat Field Eyepiece 1.25-inch Interface Astronomical Accessory
Features:
- The PF series is a high transmittance flat field eyepiece with the characteristics of high contrast, low distortion, and flat field of view. It can provide clear imaging from the center of the field of view to the edge. The PF series eyepieces have accurate color reproduction and a moderate field of view, effectively avoiding the black eye effect. Whether you are conducting astronomical observations or enjoying the scenery, the PF series eyepieces can bring a comfortable observation experience.
- PF25mm belongs to the mid to low magnification eyepiece in the PF series and is more suitable for short focus primary lenses.
- It adopts a 4-piece 3-group structure, with a pupil exit distance of 23 millimeters and a 65 degree apparent field of view. It adopts a cup shaped foldable eye mask, making it easy to find a comfortable observation position even when wearing glasses. Its focal length and flat field of view will make it a suitable companion for binoculars.
- When using short focal length refraction, it is a low-power eyepiece. Taking the 82APO BINO large binocular telescope with a focal length of 470mm as an example, its magnification is approximately 18 times. This is very suitable for observing natural landscapes such as birds, animals, and plants. Its sharpness and brightness can make the image clear and vivid, and the image seen is vivid and vivid. This series of eyepieces is designed as flat field eyepieces, which also performs well in larger fields of view.
