Explore Scientific 127ED APO, Nikon D90 unmodified. 20 lights 90 secs ISO 400, guided. 20 flats, 10 darks, 80 bias. IDAS LPS-D1 filter. NELM 4 with 7-day-old moon. Processed in PixInsight 8.1. I had originally planned to photograph M101, but the moon was too bright so picked this lovely globular. Pleased to see many of the dimmer blue stars in the cluster.
