Re: [APML] Mr.Zangs comment



 Don...

     I worked out the field of view and included in my post to usefilm... now 
he says maybe it wasn't a SCT and he didn't want to reveal 'secerts'... just BS.
I'm undecided about rebuttle to this cad... maybe I will, maybe not... probably 
not... just in case, did you save a copy of his 'copywritten' image from your 
comp page yesterday? If so... send it to me a file attachment, just in case...  
 astropix@att.net

 Thanks...

 Geoff
