Yes, thanks for the Ha info Paul (and a fine image too). I haven't done a lot of HaLRGB, but enough to know how tricky it can be to avoid the dreaded salmon overtones and look natural. This may well be a good object for some more education. Doug, I don't see any sign of it in your "tak stars", but I struggled with blue ringlets on my stars. I might try a bit of deconvolution on the blue images in a repro, and would be fun to try and get some Ha (not to mention the rest of the NB palette).

Hope the weather is kind soon. Look forward to seeing more.
