The Chroma H-Alpha 3nm Filter is essential for ultra high contrast images of nebulae under high levels of light pollution and Moon light. Normally used in comjunction with Chroma 3nm OIIIÂ and 3nm SII narrowband filters to create composite images.
The Astronomik Luminance Filter (L-2) is a high quality UV / IR block filter suitable for most instruments except refractors with imperfect colour correction.
The Astronomik CLS CCD Filter IR Blocked has all the benefits of the standard CLS CCD filter but with IR blocking built in.
This broadband light pollution filter works on all objects and can be used visually and for imaging with CCD and plain glass (full spectrum) modded DSLR cameras.
The IR Pro (742nm) Filter pushes the passband of the Baader and Altair IR pass filters further into the Infra Red. At these longer wavelengths, planetary images are much less disturbed by distortions in the atmosphere.
This is the best “Planet Killer” filter, based on research by Astronomik to determine the optimal passband for enhanced Planetary Imaging, with most amateur equipment.
Sensitivity of most CCD cameras is still fairly high in this region so smaller scopes (>5″) can benefit.
The QHYCFW3-L Large Filter Wheel supports a carousel holding seven two inch mounted or 50mm round unmounted filters.
The QHYCFW3-XL is available if 9 x 2″ / 50mm round or 7 x 50mm square filters are required.
