NGC/IC Project Restoration Effort

===== NGC 5904 = M 5. See NGC 5897 and IC 4540.

===== NGC 5904 18" (7/26/06): at 435x the cluster overfills the field and the intense 3.5' core is resolved to the center. The core has two easily resolved parallel star lanes oriented E-W that cross the core on the north and south sides and an extremely dense knot of stars is resolved on the west side of the northern lane. 17.5" (5/10/86): very bright, very large, extremely dense, edge-to-edge resolution of several hundred stars across 22' field (not possible to count), many stars arranged in arcs and streamers. Strong even concentration to a large very bright core. Third best globular cluster from northern California (5th brightest integrated magnitude) and can be glimpsed naked-eye in as a small fuzzy glow in dark skies. Located 22' NW of 5 Serpentis (·1930 = 5.2/10.2 at 11") and the star is more prominent than the globular. 13.1": spectacular resolution of several hundred stars from the outer halo to the core, rows of long streamers. 8": very high resolution of large, intense outer halo, many stars at edge of small core. Naked-eye (7/26/06): M5 was just visible naked-eye but the nearby mag 5 star (5 Ser) detracts from the observation. The globular appears as a faint, very small fuzzy glow close NW of the star. Naked-eye (1/21/12): confirmed naked-eye from Mauna Kea visitor center though the nearby mag 5 star is much more prominent.
