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.
CCD Filter for Astrophotography
Narrowband Bi-Colour imaging is a growing new trend in astrophotography, especially popular in light polluted areas, or for imaging in rural areas in moonlight.
