Great Report Paddy! Sweet 5/5 seeing, lucky you, although transparency has been superior in recent times. Guess one can't have both, its one or the other. Did you notice a knot in NGC 6221 just north of the core? There appears to be something there within the northern arm, Steve Gottleib's NGC notes support this but it's not clear on images whether it's a HII region or simply a faint foreground star(s).
Nice and clear here tonight, just preparing the scope for a 1-2am start. Finally got the secondary collimation nailed not 5 minutes ago
