Planetary IR Filter
I only have used this once for Saturn & Mars with my ASI 290MC. The filter worked well with natural looking colors.

very good, never had any problems with my orders.
Works on Mars
I got my first decent photo of Mars this year using the Astronomik IR Pro 742. Didn't need an IR filter in prior years, but it was a necessity this year between my seeing and the Martian dust storms.
