Thanks for the tip but as I am after something for visual only the CCD range of Astronomik filters make it a redundant cost for something I am never going to use and thus about $40 less than a brand new standard CLS filter. More to the point the Astronomik filters appear to be cheaper to buy new overseas and hence I suspect this is over priced ergo why it has been sitting around for so long for sale with no takers
So - still open to any suggestions if anyone has a 2" LPR filter for sale
