I've just purchased a G8N Celestron scope. They (Chinese) use a corrector lens between the secondary and the primary. The corrector is achromatic and produces the same color as a achromat refractor. What would be the possibility of having a apochromat lens made for the scope? The views for this f5 scope seem to be pretty sharp to the edge, but with the lens you get the purple haze on certain stars. Any advise? I know, buy a quality scope. This is a stand in scope until I can afford my dream combo.
