In the amateur astronomy community, particularly on forums like Cloudy Nights , is a specific magnification level achieved by combining eyepieces with Barlow lenses.
"593X" also identifies a specific industrial component, typically the of a single-row tapered roller bearing. In the amateur astronomy community, particularly on forums
: Observers have noted using a 9mm occulting Orthoscopic eyepiece paired with a Barlow lens to reach this power. : It is often used in the "deep"
: It is often used in the "deep" pursuit of challenging celestial objects, such as attempting to resolve Procyon B (a faint white dwarf companion). 598A/593X – PFI FERSA
: At 593x magnification, atmospheric "seeing" often prevents the image from settling, and diffraction spikes can obscure delicate details. Industrial Engineering: Tapered Roller Bearings
: Common versions of the 593X cup feature an outer diameter of approximately 150mm . 598A/593X – PFI FERSA
