Hi folks. My first time posting in this forum as I didn't feel ready to share my beginners efforts until now. I am however quite happy with this image of M83.
6.5hrs of OSC data shot over two nights. Integrated and processed in PI with a final tweak in PS. Interestingly, APP got the colour almost perfect (in my view) after an initial trial integration while PI didn't. I found it quite difficult in PI to extract the colour and achieved the final result via countless iterations of tweaking curves, saturation and detail. Ultimately, I liked the detail that could be extracted using PI. I like the yellow central bar and the magenta and blue arms. I don't like the CA from the Celestron SCT reducer and despite numerous efforts recombining various combinations of the RGB channels, I couldn't reduce the CA. Oh well!
