Coronado Double Stacking Filter SM60

The Double Stacking Filter SM60 from Coronado is a 60mm H-Alpha narrowband filter with a T-Max 60 tuner. Designed for use with Coronado's SolarMax 60 Telescope, the SM60 is 'double-stacked' onto the telescope's existing front filter to allow a more narrow bandpass (≈0.5 Å) - this results in a dramatic increase in visible details such as prominences and surface features.

This filter is not a stand-alone unit - it must be used with a secondary interference/blocking filter.
