IDAS HEUIB-II Filter: Supercharge Your H-Alpha Nebula Imaging
The IDAS HEUIB-II is not your average UV/IR-cut filter—it's a precision tool designed to bring out the finest detail in H-alpha emission nebulae. With enhanced red-spectrum suppression and cutting-edge IGAD coating technology, this filter boosts contrast where it matters most—while maintaining durability and stability for long-term, high-performance imaging.
Key Features – Built for Ha Brilliance, Engineered to Last
-
Enhanced H-alpha Emission Sensitivity
-
Specifically tuned to enhance the 656.3nm H-alpha wavelength
-
Suppresses unwanted red-end spectrum interference for cleaner, higher-contrast nebula images
-
Outperforms standard IR-cut filters like UIBAR-III and even the original HEUIB
-
Red-End Suppression Redefined
-
Expands suppression into the far red portion of the spectrum
-
Improves clarity and structure in emission nebulae by isolating H-alpha from background noise
-
Helps reveal finer details and subtle structures in extended hydrogen-rich regions
-
IGAD Coating Technology (Ion-Gun Assist Deposition)
-
Same advanced coating process used in IDAS’s LPS-P2 and LPS-V4 filters
-
Results in quartz-hard, ultra-durable multi-layer coatings
-
Increases adherence between layers and substrate, preventing delamination over time
-
Unmatched Environmental Stability
-
Virtually zero aging or spectral shift from changes in humidity or temperature
-
Ideal for consistent long-term use in varying climates and conditions
-
Maintains optical performance year after year—no surprises, just results
-
UV/IR Cut for OSC Cameras & DSLRs
-
Perfect for Emission Nebulae Imaging
-
An essential upgrade for photographers targeting HII regions, supernova remnants, and star-forming clouds
-
Pair with fast optics or narrowband imaging setups for stunning deep-sky results
If you’re serious about capturing crisp, contrast-rich images of H-alpha targets, the IDAS HEUIB-II Filter gives your astro camera the clarity it deserves—enhanced performance, rock-solid durability, and next-level red sensitivity in one powerful package.
