SV550 Telescope, 80mm F6 APO Triplet Refractor OTA, SV209 Field Flattener, 1.0X Flattener Corrects The Field, SV210 Camera Angle Adjuster
The SV550 series astronomical telescope adopts a 3-piece apochromat objective lens structure (1 S-FPL51 low-dispersion ED glass + 2 correction glasses) to effectively solve the problem of blue edge chromatic aberration in SV503 single ED structure imaging. To improve.
The focusing sheet uses a 2.5-inch toothed focusing sheet. The effective aperture is improved compared to the SV503's 2-inch focusing seat.
With a 1x flat field lens (sold separately) and a CAA camera angle adjuster (included with the package), you can meet the shooting needs of a full-size camera.
Dual speed focuser
The sv550apo lens barrel uses 2-speed gear focusing, which makes it smooth and comfortable during operation, allowing you to focus quickly and accurately and take beautiful celestial images.
Finder base included
Made of high-strength aluminum, it uses an anodized aluminum process and has an ultra-lightweight and ultra-thin body. Compatible with viewfinders, telescope laser pointer brackets, sinter-style dovetail mounts can be attached to telescopes, compatible with Clestron Orion, Sky-watcher, Vixen and more.
Includes CAA rotator camera angle adjuster
Connect the camera to the CAA without the hassle of adjusting the angle. You can easily adjust it to the required angle by turning this adjuster. The perfect partner for astrophotography.
APO Objective Lens Structure & FMC Coating
A 3-piece apochromat objective lens structure (1 S-FPL51 low-dispersion ED glass + 2 correction glasses) is used to effectively improve the problem of chromatic aberration.
The FMC coating makes the image brighter and clearer.
2.5 inch magnesium alloy focuser
A 2.5-inch magnesium alloy dual-speed toothed focuser is used to reduce vignetting when connecting to a full-frame camera. The tube stroke is 80 mm and the focuser load capacity is 5 kg.
Comes with 180mm dovetail plate
Additional thread: M63x1 female thread for photo adaptation
You can install a theodolite holder of the appropriate size.
SV209 Field Flattener for SV550 80mm OTA
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.

The performance is remarkable. The optic is superb, the build quality is excellent, for an affordable 80mm APO imaging scope it leaves nothing on the table. Very pleased with it. Only experts in optics will be able to notice any defects in the images it produces. It’s the telescope bargin of the century.
