Description

This asterism appears in an 8" as a suspicious glow at 90x magnification. Magnification of 130x or higher reveals the shape of this object, which can appear as a faint open cluster or even as a galaxy in nights with unsteady air. The three brightest stars form a rectangle with a fourth star. The three bright stars are visible with an 8" telescope. The fourth start marks the endpoint of a chain of faint stars which extends about 1,5 arc minutes. With 8" aperture these stars might appear as a linear haze. With the help of steady air and good transparency of the atmosphere one might identify stars of the chain with 8" and averted vision.
