Astronomical CCD photography has undergone a revolution by implementing
filters capable of selecting certain spectral bands, in order to obtain greater
photographic contrast, sharpness and focus , especially in those monochrome CCD cameras.
Baader presents a set of
5 L-RGB + H-alpha7nm filters , special for this use. Available in versions of:
- UV / IR
- Green
- Red
- blue
- Clear (contrast)
- H-alpha7nm
They cover the entire
visible spectrum and simultaneously block unwanted wavelengths. This type of filter is useful for
deep sky photography , especially for galaxies, stars and nebulae, which can emit gases, each at a particular wavelength. With this set we can have a very
versatile and practical set of filters.
The entire range of filters
are coated and polished on both sides , and the glass is of the highest quality to guarantee maximum
light transmission, around 99% . This treatment also completely eliminates reflections and halos. They are mounted on CCD cameras on
M28.5 threaded filter holder wheels .
They are available in the following formats:
- 1.25 "
- 36mm
- two"
- 50.4mm
- 50x50mm
- 65x65mm
