Astronomik L-RGB and H-alfa filters:

CCD Project 2013 part #3
LRGB-filters (1.25") for my first SX-wheel arrived today and were installed alongside with one Ha-filter. Second wheel will be installed with four narrowband filters (H-alfa, OIII, SII and H-beta) and CLS light pollution filter for pure luminance. In this first wheel H-alfa (12nm) is nice to have as fifth filter in order to fill all five filter positions and to boost for example star forming regions in galaxy images.
