      5.0 Quantum-4

      Pros:

      Excellent optics, very stable mount

      Cons:

      Long cool down time in winter

      Comments:

      I have owned this scope for over thirty years. I'm the second owner. The scope was designed and executed as a Questar clone by former employees of Questar. The scope is an absolute gem. I have used this scope as I traveled around the world and at star parties and at home when I wanted a quick look scope. The optics are flawless. I can detect no difference between the in and out of focus images. The mount is perfectly stable, the slow motions work smoothly and positively and the setting circle accurate. I can carry the scope, tripod and eyepieces out to the deck with one hand and be observing in a few seconds. The only real draw back is that it takes a while for the scope to cool down in the winter, but this isn't a flaw with the Q-4 but rather any scope that has as much glass and metal. I still use the scope at home, but do not travel with it because the airlines are not gentle and the scope is irreplaceable. If you can find one, buy it - you won't be sorry
