After all the technical jargon I was lost on the TDC issue. All I wanted to know is if it worked. I basically surmised it needs a few parts to connect the scope and TBT to it. It has not been powered up for some time. The con is a serious work in progress and something that is done during winter. Summer time you just bake like a potato in there. Visitors are not allowed in the con. It is just to hazardous really. I bump my head or crack an elbow everytime I go up to use the scope to spot some of the chicks walking in the inner harbor:p Magnification is such a wonderful thing
