Astronomik OWB CCD (EOS Clip) Type 2
Main use
DSLR cameras which have been converted for astronomical use by removing the inbuilt IR-filter or by substituting it with a filter with greater range for H-alpha, have a white balance that made them unable for 'terrestrial' purpose. The spectral sensitivity of the DSLR will be changed by an OWB-Filter to the former range. In other words: The OWB pretend to be the conventional built-in filter!
(This doesn't apply to the EOS 60Da Camera, only after market modded ones - as I found out - Mine is a 60Da!).
Filter is brand new apart from that test. Cost $200 incl freight.
Sell for $90 including postage.
Cheers!
