Optolong L-Pro 2" filter
Bought brand new, about 1 year old, great condition / practically brand new, used in a filter drawer and boxed when not used, so rarely handled with fingers directly.

The broadband targets (Comet, Andromeda, Pleiades, Dark nebula, etc) were all taken using this filter.
$200 postage included anywhere in Australia
