After inspiring NGC 604 during the last years I used very steady seeing conditions last new moon to detect as many individual stars as possible in NGC 588, NGC 592 and 595.
Interesting that Drissen et al. (astro-ph pdf, html link) published a work in which the detected WR stars are labeled.

First NGC 604. First "star peaks" could be detected in 8"+ instruments. I used a exceptional night to resolve some details.
27", 837x, Seeing I, NELM 7m+

Seems like I got WR 2, WR 4 and WR 13.

Second NGC 588. Small but most nebulous region with only 3 peaks within the nebula.
27", 837x, Seeing II-III, NELM 7m+

The conglomerate of star MC3 was visible. Also star UIT 008.

Third NGC 592. Largest and perhaps next to NGC 604 most interesting region with the most reserves for even better conditions or bigger aperture.
27", 837x-977x, Seeing II, NELM 7m+

WR 1 and WR 2 were at the limit of detection.

Last NGC 595. Similar small than NGC 588. Only a few peaks could be detected.

Only WR 4 could be detected. WR 2b seems to bright enough but could not separated from the southern (foreground?) star.
