SVBONY SV193 Focal Reducer 2 Inch 0.8X Field Flattener Telescope Accessory for SV503 80mm F7 ED Telescope. The objective lens of the OTA features an S FPL-51 extra-low dispersion glass ED element, which virtually eliminates chromatic aberration. This results in the best color correction for an ED doublet lens. The 0.8 times defocusing system shortens the exposure. It can meet the needs of astrophotographers who need sufficient exposure in a short time. With advanced refractor, it can take dazzling celestial photos without worrying about the distortion of the star points on the edge of the photo. SV182 Finder Scope with 90-degree viewing angle lets you view a more comfortable and convenient operation compared to a traditional straight-through viewing finder.
