Description
I’ve posted many m13 photos. This one was using my Starmaster with 14.5” Zambuto mirror and ZWO ASI294MC-pro camera, 1-minute total exposure time from Midwest US city with Bortle 7 sky. The propeller is a dark zone at the lower left of the cluster, a 3-blade “asterism”. The yellow and blue stars, older and younger, are very evident throughout the cluster in their respective regions.
