Lunt Solar Filters

Lunt solar filters cover H-alpha, Calcium K and white light observing. The range includes B600, B1200 and B1800 blocking filters for H-alpha and Calcium K, 50mm and 60mm Ha etalon filters, double stack modules for THa and MT telescopes, a high resolution H-alpha filter for DS modules, an ERF unit and a 2" Herschel wedge.

Larger blocking filters give a wider field for full-disk imaging, while double stacking narrows the bandpass for more contrast on surface detail.
