Orion SpaceProbe 130ST EQ Reflector Telescope Kit White

This “ST” or “Short Tube” version of the SpaceProbe 130 reflector is indeed more compact than the standard model. The 130ST reflector optical tube measures 24long compared to 33on the standard 130. The focal length of the ST’s 130mm 5.1″ primary mirror is 650mm f/5 yielding a wider field of view and brighter images for a given telescope eyepiece focal length. The 130mm aperture primary is a diffraction-limited parabolic mirror the same type used on much larger reflector telescopes costing many times as much. On a short-focal-length design like this one a parabolic mirror is a must for focusing incoming light to a point and delivering sharp detailed images. Moreover the secondary mirror is held in an advanced holder with thin 0.5mm metal vanes to reduce diffraction spikes and light loss. These features combined with the included 25mm 26x power and 10mm 65x power Sirius Plossl telescope eyepieces and quick-release 6×30 achromatic finder scope make this one sweet optical system for astronomy The SpaceProbe 130ST EQ reflector telescope also includes a collimation cap and center-marked primary mirror for easy optical alignment. The SpaceProbe 130ST EQ Reflector Telescope Kit comes with extra accessories at a great value The popular Shorty 2x Barlow doubles the magnification of any 1.25eyepiece for a power boost.
