Very Impressive Telescope
I bought the SV503 102ED telescope back in April of 2024. I was very impressed with the construction of the scope and the apparent overall quality. It took a few months for me to find a mount for it, but I did find one. Mount a little wobbly, but it works for now. I the scope to an Open House at an Observatory my astronomy club helps out with and everyone that looked through it was amazed how clear everything looked through it. I do have to say that the view though this scope is amazing compared to my other scopes. The only other telescope I have that beats this one is my light bucket 12inch Dob. I would and have recommend this telescope to anyone regardless of what level they are at. Good beginner, intermediate, or advanced telescope. This one will be in my collection for a very long time. GOOD JOB SVBONY!!!!!!
Great Telescope! Research the attachments you need first
Really love the image quality and sharpness you get out of this! Absolutely incredible scope coming from a beginner that has only used an entry level Newtonian reflector. I am having to buy various attachments as I realize what I need, but I suppose that just comes with getting in to a new hobby. For attaching a canon camera, I need to use an svbony canon to 48mm adapter, along with the 48mm to 1.25” adapter that came with it, but if I want to buy the 0.8x field flattener, then i can use the canon to 48mm adapter *without* the 1.25” adapter. But the field flattener won’t work with the other 1.25” adapters I have.
Anyhow, that has nothing to do with the scope itself! Construction is top notch. I definitely recommend this Refractor!
Excellent ED optisc & focuser
I have the 102 mm ED verson from Svbony. I have used it for visual observations and photography, it's very very nice for the planets and the Moon (with filter) clearly better than my Bresser 102/1000 mm achromat. It also has an excellent focuser.
Good quality without breaking the bank
I've been using this scope for almost 2 years. Primarily DSO astrophotography with some visual use. I have zero complaints.
An excellent semi-apo refractor
This refractor has a fantastic price performance and quality ratio. The image quality is significantly better than that of a 102/1000 mm F10 achromat, which I used before purchasing the Svbony 102/714 mm ED. It's focuser is also excellent, very smooth and pleasent to use.
I highly recomand this telescope.
Great combination for astro and nature
Have had my SV503 102mm for a few weeks now and is very pleased. Changed out my 10" dob for the SV503 to get more usage and flexibilty. And what a pleasant surprice it has been. Bought it with a SA409-SA410 tripod and a SV222 prism and a few baader hyperion i already owned to get a big spotting scope and a vercitile optical astro telescope. It matches my fathers more expencive spotting scope in the nature and excel it on astro objects. I can easily see the individual rings of saturn and the bands and spot on jupiter. Havent had the chance to watch andromeda or the orion nebula yet.
I will have many nice sessions with it for years to come. Very pleased with my purchase and would higly recomend the SV503
Much better optical quality and performance
I own the Svbony 102/714 mm for 6 months now, previosely I had a Bresser 102/1000 mm F10 achromat and the Svbony 102 ED has a much better optical quality and performance. Also the 2 speed focuser is infinitely better than the ones used on simple achromats.
Suitable for planetary photography
I bought this exact OTA a month ago and I tried planetary photography and the results surprised me a lot.
High performance and well-build quality
I bought the SV503 80 and I'm very happy with it's performance and build quality.
This scope will make your astrophotography a real joy
I have the svbony 503 80ED and the sv550 122mm, I started astrophotography seriously at the end of last year.I'm a real fan of the Svbony brand.
