Re: Re: [APML] Tech Pan Unhypered



Gene,

<<<Well, crud.

Did you try it at f/3.3 unfiltered?>>>

Being stuborn, I tried unhypered TP on two separate occasions in my f/5.5 t-stop Slevogt.  Both were 90-minute exposures of M31 unfiltered.  Almost nothing but the nucleus.  The film might work unhypered in an f/1.5 Schmidt.  Don't know.
