I am selling my .2 ASO Solarspectrum H-alpha filter for $3800.00 firm, ( That is a $800.00 savings). Honestly I have owned several H-alpha filters, and I believe it is more like .4, although I am not an expert and it is just from comparisons. I bought the filter directly from Mark Wagner in 2005.
However, if you have been a solar observer for years you will know that during that period we were in the deepest minimum in 100 years. Consequently, it was much easier to setup my Coronado 60 to take peeks at the sun. In other words it has been lightly used. New Solarspectrum filter is $4600, and possible a two year wait or longer. See this link for photos, and I am selling the filter separately.
