HI RICK,
ON A Ha FILTER I WOULD PREFER TO USE TWO FILTERS
FACE TO FACE. THE Ha FILTER IS VERY FRUSTRATING
TO PRODUCE WITH VERY HIGH FAILURE RATES THEREFORE
HIGH PRICES. TWO YEARS AGO I DEVELOPED ABSORPTION
FILTERS THAT ABSORBS MOST OF THE IR WITH A MAX
AT 56Onm AND ZERO AT 460nm. UNFORTUNATELY THE SLOPE FROM 560 TO 690 IS GRADUAL. USING THESE
FILTERS MAKES IT EASIER FOR THE Ha INTERFERENCE
FILTER.
