The Tele Vue Powermate 5x increases your telescope\u2019s effective focal length to provide a nominal magnification of 5x using the same eyepiece. It allows you to expand your range of eyepieces without changing instruments, particularly for observing the Moon and the planets. Its telescope-side thread is in the 1.25 inches (31.75 mm)<\/strong>. The version number is PMT-5126<\/strong> : The factor and diameter must be considered together when making a selection.<\/p>\n Tele Vue combines a negative doublet with a positive pupil-correcting doublet. This four-element design magnifies the image while maintaining the intended exit pupil position for the eyepiece. This prevents the Powermate from being treated as a simple negative Barlow lens. It is particularly useful with long-focal-length eyepieces where you want to maintain a comfortable eye relief.<\/p>\n This model mounts in a 1.25-inch eyepiece holder and is compatible with an eyepiece of the same size. For a camera, check the connection cable and focal length. Specific photography adapters are sold separately: a camera adapter is not included by default with this kit. The focal ratio used in photography must be verified in the Tele Vue documentation corresponding to your setup.<\/p>\n How do you calculate the magnification?<\/strong> Divide the telescope's focal length by that of the eyepiece, then apply the nominal magnification factor of this amplifier as intended for its configuration. Very high magnification can reduce apparent brightness and accentuate turbulence: choose a reasonable combination for your instrument.<\/p>\n Is it compatible with any camera?<\/strong> The insertion diameter alone is not enough to guarantee compatibility with a camera. You must also check the mount, the focal length, the field of view, and whether the camera can be focused. A camera or telescope is not included.<\/p>\nA Powermate, which is different from a traditional Barlow lens<\/h3>\n
