SVBONY SV550 Telescope, 80mm APO Triplet Refractor OTA, Bundle with SV209 Field Flattener, 1.0X Flattener Corrects, SV210 Camera Angle Adjuster, M63 360 Degree Rotator, for Deep Sky Astrophotography
The telescope uses an air-spaced triple optical design that virtually eliminates chromatic aberration; resulting in bright; high-contrast images for exploring galaxies with better graphic clarity
The triplet apochromatic optics structure (1 piece of S-FPL51 low-dispersion ED glass and 2 pieces of correction glass) effectively improves the blue-edge chromatic aberration problem of single-ED structure imaging
SV209 is a special field flattener for SV550 80F6 OTA; which can effectively improve the image quality problem of SV550 OTA fringe field curvature
Built-in 2-inch filter mounting thread; supports 2-inch filter installation; customers do not need to buy a filter adapter ring separately
CAA 360-degree rotator; improve the stability and portability of the shooting process; it is mainly used for astrophotography scenes
