180mm clear aperture ND 3.8 solar filter
Relisted as the buyer changed his mind.
This filter was used on my 180 Mak for solar imaging,
I had to sell the Mak due to a chronic back condition,
The filter is 3 months old and in perfect condition.
Please note this filter is for imaging only, it is not suitable
for visual use. Selling for $120 posted Australia wide.
