The 10 biggest telescopes on Earth | Space They are priced low compared to other telescopes of the same size, are easy to use, and help you learn the night sky. You can use the SPIDER 230C with your equatorial mount (in order to work, the SPIDER 230C kit without mount requires an equatorial GOTO mount with at least 50 kg payload capacity, Losmandy-type style dovetail clamp). Consumer-grade telescopes can have imaging defects such as color fringing a kind of chromatic aberration that happens when the lens is unable to bring all wavelengths of color to the same focal plane. These old-time "solar filters" have been known to fall apart in mid-use because the sun actually melted the glue or other adhesive holding them together! I can detect down to 20th mag in 5 minutes with a conventional CCD and no filters but at a SNR that's just above my noise floor. An Imaging Newtonian is a fast reflector telescope that is normally optimized for astrophotography or astro-imaging. Have you watched a piece of paper catch fire when light was shined on it through a magnifying glass? Thats because reflecting telescopes use mirrors, which provide more sensitivity to all wavelengths of light and dont cause chromatic aberrations like color fringing.
