Hi,
Got to test the "Mars 2003" filter from Sirius Optics. My initial impression is that its most directly comparable to my orange Wratten filter. Still the Mars filter showed more detail in "breaking" the darker albedo features. Additionally, limb brightening was white while the polar cap had a magenta tint. The downside was less contrast regarding the Polar Cap & it was a bit more difficult to achieve best focus with the Mars filter as compared to the orange Wratten.
Right now I believe the VFS to be far and away the best on Mars. Settings of 220 and 190 show best detail. Setting of 135 shows most detail with most natural looking color.
Thanks,
Sol Robbins
