Second image from my  StellaLyra 6" f/9 Ritchey-Chrétien Telescope, capturing NGC2359 Thor's Helmet or the Duck Nebula down in Canis Major. More info on Wiki...NGC 2359 - Wikipedia

52 useable subs captured over 3 nights last week though this time I used a dual-band filter (IDAS NBZ) with the OSC camera to capture the Hydrogen Alpha and Oxygen emission lines as the bright Moon was about. NGC2359 transits at only 23 degrees above the horizon here and so I have around 2 hours to catch it between the local roof & tree lines. I'd like more time to improve signal levels but this seems reasonable for just 4.5 hours.
