Thanks for the tip Starkler, it was already on my list, I'll just move it up a few places.
It's funny how it can be reasonably dark and clear outside with minumal wind and still either the seeing or transperency is not that good. There is always something to try and teach yourself. The learning curve over the last Month or so has been pretty steep, odd thing about this past time, I don't see it flattening out any time in the near future.
Clear, less light polluted skies for us all!
