Filters for Astrophotography
With modern interference filters, amateur astronomers can now achieve excellent image results. The applications include narrow-band emission line filters, broader-band color filters and filters for suppressing artificial light emission.

The nebula filter passes H-Beta, O-III and H-Alpha and is designed for astrophotography.
IDAS nebula filters are produced in Japan The NB1-48 is supplied in a filter cell with M48x0.75 / 2" filter thread Exposure time factor 4 - four times the exposure time is possible before you reach the sky background. The filter is especially well suited for tricolor shots of nebulae with color cameras Scattered light and nightglow are effectively suppressed, leaving stars and sky background relatively neutral High-quality anti-reflection coating Scratch-resistant hard coating With 2.5 mm thickness the filter is parfocal to other IDAS filters The infrared light is blocked, so the filter also fulfills the function of an IR blocking filter. Omegon Infrared Blocking Filter 1.25".
Optolong 3 nm H-Alpha Ultra - Narrow band filter for astrophotography - Shooting with extreme contrast even with strong light pollution. 2" mounted with filter mount Suitable for telescopes and lenses with focal ratios of f/3 and lower Blackened edges to avoid internal reflections Extremely narrow bandwidth of only 3 nm for maximum contrast Central wavelength 656 nm Optolong 3nm OIII - Narrow band filter for astrophotography - Shooting with extreme contrast even with strong light pollution. 2" mounted with filter mount Suitable for telescopes and lenses with focal ratios of f/3 and lower Blackened edges to avoid internal reflections Extremely narrow bandwidth of only 3 nm for maximum contrast Central wavelength 501 nm Optolong 3nm SII - Narrow band filter for astrophotography - Shooting with extreme contrast even with strong light pollution. 2" mounted with filter mount Suitable for telescopes and lenses with focal ratios of f/3 and lower Blackened edges to avoid internal reflections Extremely narrow bandwidth of only 3 nm for maximum contrast Central wavelength 672 nm The L-Pro Astrophotography filter is a filter for improving the contrast of deep-sky objects and dampening the sky background.
blocks UV and IR (700 - 1100 nm) high transmission at passband improved color balance for DSLRs and One-Shot Color Astro Cameras, e.g. ASI Color Cameras cooled or uncooled by ZWO. high optical quality in 1.25" filter cell The L-Pro Nebula filter permits roughly 3x longer exposure times than without a filter and therefore improves contrast significantly. The L-Pro Astrophotography filter is a filter for improving the contrast of deep-sky objects and dampening the sky background.

This dual band filter is designed to drastically reduce the effect of light pollution, it isolates the nebulae´s emissions into H-Alpha (red) and OIII (green-blue) and blocks light pollution.
Transmits the main nebula lines at 656.3 nm and 500.7 nm with 3 nm bandpass Blocks light pollution and skyglow Designed mainly for astrophotography Especially suited for color cameras Ideal for urban areas with extreme light pollution Incorporates UV/IR cut filter Multi layers anti reflection coating Ultra thin filter cell maximises compatibility with filter wheels Broad band filter for city light suppression, also suitable for small aperture
Filter with the highest contrast and very good transmission for demanding astrophotography
Broad band filter for city light suppression, also suitable for small aperture
Blocks IR and UV light for improvement of contrast during imaging
