I have a set of LRGB 50mm square Astrodon Generation 1 filters in excellent condition.
AUD$375 including postage to Oz/NZ.
New Astrodon Gen 11 50m square filters (49.7 actually) are about AUD$1710.
These filters are blackened on the edges and will be very good on many setups. If you are using a refractor with a corrector or then perhaps Gen 11 would be better for halos. I did not get halos on an FSQ106 and STL11 or 16803.
You can also get them cut down to smaller sizes if you don't need 49.7 square. That makes a cheap option. Astrodons are definitely the best filters. I've used several brands.
