SVSVBONY 550 80 APO Telescope - 1.0x Field Flattener for Astrophotography

Photography Set Includes:
SV550 80 APO telescope OTA 
SV209 1.0x filed flattener & focal reducer
SV210 M63 CAA 360 Degree Rotator Camera Angle Adjuster
Use this APO OTA apochromatic refractor to reveal the wonders of celestial bodies; you can observe the Messier catalog targets; the common shooting targets M42 M45; the difficulty factor is simple
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
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
This little scope also includes the use of a 2.5-inch magnesium alloy dual-speed toothed focus mount (1:10); which reduces vignetting on full-frame cameras and reduces the weight of the support platform
This APO adopts extreme extinction measures; there are multiple light barriers inside the focusing seat and the inner wall of the lens barrel; and 4 extinction barriers are designed to meet the ultimate pursuit of extinction
SVBONY SV209 Field Flattener 1.0x for SV550 80F6 Astrophotography M63x1 Connection Black
SV209 is a special field flattener for SV550 80F6 OTA, which can effectively improve the image quality problem of SV550 OTA fringe field curvature; At the same time, the focal length and focal plane position of the primary mirror remain unchanged;
The package of SV209 is equipped with an M63 extension tube and an M48 adapter ring to ensure that the back focal length of the flat field mirror is the astronomical conventional 55mm length;
The effective field of view of the 45mm large target surface supports not only half-frame cameras; but also full-frame cameras;
Built-in 2-inch filter mounting thread; supports 2-inch filter installation; customers do not need to buy a filter adapter ring separately;
Maximum working distance from the M63x1 internal thread: 103 mm - space enough for almost all adaptations.
SVBONY SV210 M63 CAA 360 Degree Rotator Camera Angle Adjuster for SV550 80F6
Camera angle adjuster; The CAA image field angle adjuster can easily adjust the shooting angle without rotating the main mirror, saving customers the tedious installation and disassembly process;
CAA 360-degree rotator; Improve the stability and portability of the shooting process, it is mainly used for astrophotography scenes;
Camera angle adjuster for SV550 refracting APO telescope, also compatible with astronomical telescope lens barrel with M63x1 threaded astronomical focusing mounts;
locking screw M4; With locking and positioning function, the camera can be positioned at any position;
CAA with field flattener can correct the defects of the field curvature of the shooting target, and improve the imaging quality and shooting efficiency at the edge of the field of view;
