CL RF calibration
So I test drove my cheap CL from Ebay and the RF is off vertically and apparently horizontally at infinity as well.
I know where the c alibration screws are and have an M here for comparison - is self-calibration a viable option, and if so, how best go about it? I think vertical first, then horizontal at infinity and then 5m, or?
I guess trial and error may get me there in the end, but any advice is appreciated.
