SVBONY SV550 80mm Telescope is well-suited for observing and photographing the Moon, planets, and especially deep-sky objects. Its triplet APO optical structure ensures true-to-life color,rich detail, and high contrast. Weighing only 3.75 kg (8.27 lbs), it is highly portable for easy transportation. Most astronomical telescopes have a certain field curvature problem, which can be improved with SV209. The SV209 is a special field flattener for SV550 80F6 OTA, which can effectively improve the field curvature of fringe field images. Great for astrophotography. SV220 H-Alpha and O-III 3nm Dual-Narrowband Filter enhances astrophotography by reducing stray light and light pollution, suitable for capturing deep-sky objects. SV405CC cooled color astronomy camera is designed with imx294 color cmos sensor; the imx294 sensor adopts the 4/3 format and provides the necessary number of pixels for true 4k output at 120 frames per second. SV226 filter drawer adopts integrated CNC molding and anti-light leaking design. It can compatible with 1.25" & 2" specifications filters on the market. Strong magnetic attraction, prevent the filter from falling off.
