## Description

Full description not available

## Features

- 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

https://www.amazon.com/dp/B08DN63919?ref=myi_title_dp

**Q: What kind of star tracker can be used for this telescope?**
A: I have my 550 svbony triplet on a sky watcher eqm-35 goto mount. The eqm-35 mount is more than capable of handling the weight along with all the astrophotography Equipment I have on it.

**Q: Is there an adapter for connecting a nikon f-mount dslr to this?**
A: Yes. On the svbony website is the SV194 Photography Adapter for Nikon Cameras. The one from svbony has both m42 and m48 Size threads. You can find many different brands if you search for "T-mount  adapter for Nikon F-mount"

**Q: Where do I get a 2 inch T mount for nikon?**
A: Have you tried Amazon? :P search for "telescope 2" t mount nikon" and you should find a bunch. Note that you might end up with two pieces. One is the t mount usually with M42 threads, the other is the ring that connects to the camera and t mount. Just make sure the threads are the same, if they seller can't specify that I wouldn't buy from them.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Top Quality at a Bargain Price
*by R***H on December 6, 2024*

It's easy to pay over 5000 dollars for APO triplet refractor. When SVBony offered one for under 1500 dollars, I was skeptical. Yet, reviews were excellent. I could not pass up the temptation to purchase the SVBony 550 refractor. I could not be more please with my choice. There is zero chromatic aberration, even on the planet Venus. Images are extremely sharp. Focused stars show textbook perfect diffraction rings at high power. Planetary images are incredible. The cloud belts of Jupiter exhibit bewildering detail. Also, I love the exterior fit and finish. The focuser is extremely robust. It. can easily support the heaviest 2" eyepieces, as well as the heaviest, full frame 35mm digital cameras. If you want to enjoy top performance in a 5 inch refracting telescope, look no further than the SV550.

### ⭐⭐⭐⭐⭐ Very nice OTA, excellent for astrophotography with the corrector
*by R***S on November 12, 2022*

The build quality is superb, the optics are bright and sharp, the focus mechanism is extremely solid and smooth. The entire assembly is much more solid that it appears to be in pictures. Definitely a higher end scope. Pretty thrilled with it so far.Edit—After getting some more clear nights boy this thing performs beyond expectations, I’m imaging with the ASI2600MM pro in mono with it and wow, pinpoint stars across the entire feild, no aberration noticeable at all. This scope is the deal of the century. If you’re on a budget and looking for a very high performance APO for astrophotography then it can’t be beat there’s nothing I’d complain about. I mounted it to a Losmandy rail to add room for power supplies and my imaging computer. I still haven’t had enough clear night to really push it to it’s limits but having taken some images under less than perfect conditions the results are impressive to say the least…

### ⭐⭐⭐⭐⭐ Wow X2
*by N***2 on May 28, 2024*

Ordered the SV 550. Received it a couple of days ago. I inadvertently ordered the 80 mm instead of the 122 mm. It was my mistake.Although I had initially desired the 122 mm, I was impressed with the ease of set up and the quality of the 80 mm. I had always used Different types of scopes, including the rasa, and a couple of SC 8’s etc. . Nothing was easier than setting up the telescope with an Orion eq 26 mount. I was very impressed with the visual and a brief session of photography with using zwo 2600 color. I incorporated an ASI air, electric auto focus, Lens flattener (not a reducer), , backspacing, scope camera…etc. It was a very nice neat package that fit in my gym bag! It was approximately 14 inches long by about 9 inches high. I didn’t weigh it but I suspect somewhere around 11-12 pounds. I can now “go lighter” and feel confident That I did not make significant sacrifices. Something that I’ve been looking forward to for sometime.I think I’m keeping the 80 mm.This is an update: I ordered the 122 after having decided to keep the 80 mm as well. The 122 came double packed and inside the second box was neatly placed telescope in a well packed carrie bag.I have only set it up on the mount now but it’s like dad and little boy. Although the 122 is quite manageable, It does weigh twice as much as the 80mm but still keep it in the range appropriate for medium capacity mounts.I am putting a Dual scope mount on my AVX and will be able to use both telescopes simultaneously for camera, viewing, or any combination of both.The combination of these two triplets, ais a. great value and compared to the price of a single Rassa 8., I believe I have a true value in owning both of these scopes.
