Remark: The Helix Nebula shot during a good night at Athos Centro Astronomico. The raw frames had a very good SNR and no gradients. Hence I had not to process the pics really much. Only slight denoise, color calibration, selective sharpening, masked stretch and manual stretch, LRGB combination, selective adjustment of saturation using different masks. Final cosmetics in PS.
