Highest transmission:
Our new MaxFR filters are designed to work perfectly with fast optical systems. The MFR Coating technique provides the best out-of-band blocking possible across the range of wavelengths from UV to IR. The new design offers extremely high contrast, minimized stray light, no halos, and needle-sharp stars. Astronomik MFR narrowband-emission line filters provide the best data quality for producing stunning final images.
For maximum contrast, the SII filter is carefully designed to block all light from H-alpha and NII (nitrogen).
Imaging with Narrowband-Emission Line Filters
Narrowband-emission line filters are perfect for observing from light-polluted areas. H-alpha filters should be your first step into narrowband astrophotography, allowing deep, contrast-rich images even in severe light pollution or under a full moon. H-alpha filters are ideal for capturing red-glowing nebulae. OIII filters enable imaging of greenish-blue structures, such as planetary nebulae and star-forming regions. SII filters complete your HSO set, letting you process your images like those taken by the Hubble Space Telescope!
Quality aspects of the new Astronomik MFR narrowband-emission line filters:
You’ll get the highest quality with every Astronomik filter, enhancing your imaging possibilities. These filters provide long-lasting performance, working as well as when they were brand new. With our special coating, the filters do not degrade over time, and the MFR coating ensures compatibility with nearly all optical systems.
Frequently Asked Questions:
It depends on your setup. For DSLR cameras and dark-current-limited cameras, 12nm filters are ideal. For extreme light pollution and cameras with low dark current, 6nm filters provide better contrast and star reduction, making them suitable for deep imaging.
Using narrowband filters doesn’t necessarily require longer exposure times, but you can extend exposure to record fainter details without unwanted light interference. This results in clearer images, even from light-polluted areas.
