I tried several times to see NGC 2158 with a telescope from the suburbs. My wonderful 6" f/8 would only show me one star. My C8 would show me that star and hints of two others. My CFF 290 Classical Cassegrain would show me those three and a glow with averted vision, on the night I tried it. With a camera on a small scope, the cluster stands out. This is just 16x600" with the Atik 460EXC through the SWED80 at f/6.375. I am always impressed with the optical quality of the ED80, and the flattener/reducer does a superb job.
