”’NGC 6281”’ (also informally known as the ”’Moth Wing Cluster”'<ref>{{cite web | title=NGC 6281 the Moth Wing Cluster | website=AstroBin | date=2023-09-19 | url=https://www.astrobin.com/405971/ | access-date=2024-07-15}}</ref>) is an [[open cluster]] of stars in the constellation [[Scorpius]]. It was not included in the [[Messier object|Messier]] or [[Caldwell catalogue|Caldwell]] catalogues of nebulous objects, but it is the brightest such cluster in the constellation to be left out of both. It is readily observed with the naked eye; it is located about {{formatnum:2}}° to the east of [[Mu Scorpii]]. [[James Dunlop]] described the cluster as a “curiously curved line of pretty bright stars, with many stars mixt”. [[John Herschel]] then described the cluster as both “pretty bright” and “pretty rich”.<ref name=crossen_rhemman2004/><ref name=omeara2007/>

This cluster has a tidal radius of {{Convert|26|ly|pc|abbr=on}} and a mass of about 214 [[solar mass]]es.<ref name=aaa477_1_165/> It is classified as a type II2p cluster and has 55 members with a [[visual magnitude]] of 13.5 or greater within 20&nbsp;[[arcminute]]s of the center.<ref name=aass61_45/> The brightest member is 9th magnitude.
