In SETI analysis, is it more interesting to see a wider bandwidth signal, or single frequency bins of larger magnitudes? If you would rather see wider bandwidths, it might be interesting to set each of N bins to an opacity of 1/N and draw them on top of each other. That way the more that are drawn on top of each other appear darker in appearance (wider bandwidth) as opposed to a single outlier skewing all results. Moreover, for zooming, I think this would be the most dynamic while maintaining full fidelity of the signal representation. I think there are a lot of good visualizations that can be done without compromising the frequency resolution you have obtained with such large FFTs. I'd be interested to hear what method you end up using, and what is important in your SETI analysis.
