Omegon Pro SII CCD Filter 2 inch: sulfur channel for large sensors<\/strong><\/h2>\n\n\n\n

This narrowband filter targets the SII emission line of ionized sulfur around 672 nanometers, a staple of the classic Hubble palette. The 2-inch size is intended for large sensors and high resolution.<\/p>\n\n\n\n

Detail that otherwise falls away<\/h4>\n\n\n\n

With this filter, you can capture faint filament structures and details in emission nebulae that would otherwise remain completely invisible. The narrow bandwidth of approximately 6 to 7 nanometers provides high contrast even with moderate light pollution.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Moonlight, artificial light, and unwanted starlight components are suppressed, while high-transmission sulfur emission is passed through. This allows for longer exposures without the background becoming saturated.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Objects to start with<\/h4>\n\n\n\n

Classic targets are the Horsehead Nebula, IC 443 (Jellyfish), and the Rosette Nebula. In SHO combination with H-alpha and OIII, the familiar color palette arises from them.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Featured accessories<\/h3>\n\n\n\n

Combine with the 2-inch Pro H-alpha and an OIII filter of the same size for a complete SHO set in your 2-inch filter wheel.<\/p>\n\n\n\n
