Thanks for the reply.. btw, there is a dude called John chen (founder of svbony).. he deals with optolong originals and OEMs.. you would be able to get knock off prices from him for any of the optolong filters if you mail him via his Facebook...

In fact, I was offered the 2inch l enhance for USD190 (approx AUD30 cheaper than cyclops)..
His svbony UHC, CLS, Oiii filters etc. are all optolong OEMs and perform on par at a fraction of the cost..
