This is what we're trying to determine, Rich.
Understood. However, just as it easier to make a 6-inch mirror AND a 12.5-inch mirror than a 12.5-inch mirror alone, it will be easier for CuriousOne to make better decisions and ask more pointed questions by taking some time off to read a little on optical realities. Stuffy or not, without doing so, this thread will grow to be 10 pages in 4 more days and CuriousOne will know little more than he does now. But, I have approached that logic several times to no avail, so I will stop recommending it.
