The Lunt 60mm H-alpha Etalon 60mm aperture filter will reduce the bandpass of a Lunt LS-60 solar system (not included) to <0.5 angstroms - dependent slightly on the telescope.

I went from a 50mm stack to a 60mm Lunt stack to improve overall performance. While the aperture change didn't have as dramatic a result as I thought, I am very pleased with the performance of this stack. (Posted on 9/15/2015)
