CHIUSO
Vendo filtro Baader con le seguenti caratteristiche:
Good contrast enhancement and reduction of false colour at refractors.
The Fringe Killer is a further development of the simple minus violet filter. It lets more of the blue light pass thus causing less colour shift. Additionally, contrast is enhanced significantly.
The Fringe Killer is recommended for every achromatic refractor from 70 to 150mm aperture when the user wants to reduce the false colour inherent to the system and increase contrast.
