Baader Ha 35nm CCD filter 1.25"
I bought three of these filters (#2458381) for trials with various blocking filter combinations on solar telescope mods.
It's a perfect alternative to a failed ITF in a Coronado blocking filter diagonal.
I've used one so far and would like to sell at least one of the others.
In the original sealed container.
Ideal for DSO imaging with a slightly larger bandpass.
$100 delivered.
