Helix with Baader narrowband o3 filter
Did this tonight, lots of moonlight about.
Only did 2x10 mins, was curious to see what it would look like using the o3 filter. Would look better with more exposures. This is where monochrome Astro CCD cameras come in handy as they get all the pixels, wheeras I was only getting green and a little bit of blue.
