I don't use the following filters any more and such i have three very good filters up for grabs.
Orion Skyglow light pollution filter for suburban or city skies. PENDING...
Baader fringe killer this colour error-correction filter is a must for small achromat refractors
Baader UHC-S blocks city lights and increases contrast of Nebula PENDING...
All work great for Visual and photographic
Each is at least 50% less than brand new and in v good nick ( the Orion label is worn a bit but the filter is cool.
Asking $60 each, but we can come to an agreement if you want more than one
Each comes with a padded box and i can post if you live outside of Perth.
