SVBONY SV550 APO Triplet Refractor 80mm F6 Telescope OTA For Deep Sky Astrophotography and Visual Observation
5 | Reviews- 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
Note: This SV550 80 OTA comes with a dedicated dovetail slot for the finderscope.

SV550 APO Triplet Refractor 80 F6 OTA For Visual & Deep Sky Astrophotography
The SV550 APO Triplet refractor with 80mm aperture and fast f/6 focal ratio, it is definitely a great travel telescope for observation and astrophotography.
Apochromatic 3-element Objective
The triplet apochromatic optics structure (1 piece of S-FPL51 low dispersion ED glass + 2 pieces of correction glass) is adopted to significantly improve the image quality of the captured image (15.8% increase by the spectrometer calculation). Significantly reduces edge dispersion resulting in blue fringing problems.
2.5 inches 1:10 Dual-speed Focuser
The 2.5-inch focusing base can effectively reduce the vignetting problem when connecting to a full-frame camera, and the FPL51 APO can improve the quality of the captured images.
The Elimination Of Stray Light
4 extinction light bars are used inside the lens barrel, which can eliminate all stray light interference on the inner wall of the lens barrel.
Focal Lenght of 480mm
To remove the 2-inch adapter from the focuser, you will need to loosen the three small screws on the side of the adapter (as indicated in the red circle in the image). Please use an appropriate Allen wrench to gently loosen these screws; there is no need to completely remove them down. Once the three screws are sufficiently loosened, you can turn the adapter counterclockwise to detach it, allowing you to proceed with installing the SV209 flat field lens.
Additionally, if you experience any loosening of the focuser adapter during use, you can also adjust the tightness of the small screws to secure it properly.

I’ve been using the SVBONY SV550 80mm APO Triplet for a while now, and I’m honestly blown away by the optical quality and build for what it costs. The images come out sharp and beautifully color-corrected, with zero noticeable chromatic aberration. The dual-speed focuser is smooth and precise, and the overall finish feels premium. It’s light, easy to handle, and works perfectly for both visual observing and deep-sky astrophotography. Highly recommended!

I've used the Sv550 80ED as my main imaging scope for 2 years. I've been so impressed with the quality for the price that I've recently purchased a second one. It truly is the ultimate budget triplet. I would definitely recommend this OTA to anyone who is interested in putting together a quality rig on a budget.

This is a bargain 80mm triplet meant for astrophotography. Produces excellent images with the right camera. If you want to make it faster and wider field of view for your camera, get the reducer that is made for the 80mm doublet, it works 100%, just like the dedicated flattener for the triplet. Highly recommended.

Just acquired the scope and am very impressed with the fit, finish and function. Visually, the scope performs as hoped. I am looking forward to some deep sky imaging this weekend to round out my review.

My title describes how I feel about this telescope, great quality, dual speed focuser, no chromatic aberration at a GREAT price. Good job Sbvony!, Good job! 👏 👏 👏 If you want to use 100 of your pictures get the flattener. That will be my next purchase.
