Return to M 57
Prior to attempting NGC 6888 I revisited M 57 to see if I could pick up the extra two stars I felt I should have got on my earlier attempt within the nebula. Success was achieved though it took several goes at processing to get them to show with any clarity. Details: 8x 4 minute exposures @ iso400 with CLS. Stacked and processed in CS2.
