Baader 2" Semi APO Filter (optically polished)

The combination of the NEODYMIUM & IR-Cut 2" (Moon-& Skyglow) Filter  with the Fringe Killer Filter 2" (Phantomgroup Coated) is a remarkably cheap solution for achieving colour-corrected images with cheap refractors, but be aware that with this combination some reflections may appear on the image. Baader has reviewed these customer reports and came up with the solution: this very semi-APO filter.

By using this Semi-APO filter you will experience a practically neutrally tinted image without the red and blue halo that would otherwise ruin images takes through a low-cost refractor.

Never use any eyepiece filter for solar observation without objective front filter!
