I wasn't happy with my first attempt so I added 3 hours of O3 and reprocessed from scratch.
Still could with more data to tame the noise, but I think this one looks a little better.

This my first Bi-Colour image. Ha>Red, O111>Blue and Green
Image taken with W.O FLT110 and G2-8300 Moravian CCD. Astronomik 12nm filters. Processed in Pixinsight.
Total image was 23 O111 and 26 Ha subs at 10min each.

Image was quite noisy and required significant noise reduction. I now understand why long subs are required for narrowband images.
Any tips for future Narrowband processing gratefully appreciated.
Thanks Geoff
