I thihk your FS152 is a much better match for the ST2k. The color is always much better.

Greg,
Pretty cool. I get a real 3D effect on my monitor.

So the color seems a bit magenta to me (could be my monitor). I notice that you expose green at 1/2 the time. Do you have some calibration data on your filters that suggest that exposure ratio?

Nice work Greg! The detail in the core area is quite nice.
