What the listings publish
More than the price would suggest. The CLS filter gives its transmission at five nebula lines and three light-pollution lines. The 20 mm 66-degree eyepiece publishes 16 mm of eye relief. The SV205 gives its sensor, 1.45 µm pixels and frame rates; the SV105 names its capture software for each operating system. The 5x24 finder warns that its bracket will not fit a dovetail base.
The UHC filter gives no wavelengths. The SV106 guide scopes do not state their focal length outright. The SV28 spotting scope leaves out its prism glass.
