SVBONY SV503 Astronomical Telescope 102mm F7 ED Extra Low Dispersion Refractor OTA for Astrophotography

The 503 102 is a good choice. It is just big enough to enjoy some details in distant DSOs and small enough to get a decent field of view as well. Alternatively, I have opted to not use the reducer/flattener to maximize focal length for some targets as well.

I have tested it's SV503 102mm refractor. Pretty good, stars are sharp and round everywhere. Light weight too .

Great scope for Astrophotography beginners. It is well constructed and made solid. It's compact. Easy to breakdown, pack it up and move around. However, I only had once chance to use it since received. Mostly cloudy nights, not good for observations. During the one night used, it performed great with my onboard planetary software, PHD2, Sharpcap and CDC. I was able to capture the M42 briefly as a test run. It turned out well for the first time. This is a great scope considering the cost. I was looking for something that wouldn't break the bank. I'm totally satified with it. I went further installing the ZWO EAF auto focuser. It works great and perfect match for the scope, easy to install. The ZWO ASI533 mc pro camera is compatible with the scope. Perfect match. I highly recommend this scope for beginners, like me!

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!!!!!!

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!

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.

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

I bought a SV503 102mm ED as my first ever scope in early 2022. It has proven to be a sturdy and well manufactured piece of equipment that is a pleasure to use for astrophotography. There is no evidence of any fringing or aberration in my images. The focuser is very smooth to use and remarkably stable over a deep-sky photography session. The auto focuser was easily installed as per SVBony's recommended method and handles the task without difficulty. Teamed up with the SV106 guide scope and Phd2 software, the combination produces clear and well contrasted images. There is some field curvature out near the edges of the images but I am confident that the flattener that I have on order will fix that. I have to say that I actually much prefer using the SV503 rather than my more recently purchased 8" SCT. All in all, a great buy..!!

I purchased the SV503 102ed scope and the sv193, 0.8 reducer and just last night had the chance to put it to use. I added the sv503 70mm scope as it's guide scope. Added the ASI1600mm pro camera and after the Horsehead Nebula was in striking distance, I managed to get a few HA shots and then stacked them. Only using 5 images at 5 minute subs, I was blown away at the quality of the picture. Of course, using Narrow band filters there was no CA at all, even still, I was thoroughly impressed and pleased with the quality of the pictures. SVBONY did an excellent job with this scope. There is no place to add a picture here otherwise I would have shared that with you.

Hey guys, I recently got a new refractor. The Svbony SV503 ED 102/714. My first refractor with ED glass. In terms of quality, the whole telescope comes across at a high level. It is built solidly and just feels valuable.The dual-speed-RAP-focuser is my highlight! My God! It glides so nice and soft ... now focusing is always a pleasure. Nothing grinds when focusing and there is also no silicone grease that sticks to the fingers. A rotating focuser and ring clips add value to the telescope. But even such simple parts as the screws are milled very filigree and can be moved very smoothly. The lens cap is made of metal and sits well on the dew cap, which can also be moved. That reduces the dimensions during transport. Without tube rings, the tube weighs 3353 g. The ED glass makes a very nice, clear image. Chromatic aberrations only come to light at high magnification and in certain light situations. Finally I can make observations during the day (with low power eyepieces) without disturbing chromatic aberrations. Just yesterday I was watching the moon and I didn't notice any chromatic aberrations! Not even with my Baader Classic Ortho 6mm! Maybe it was because of the position of the moon... I don’t know… All I can say: Svbonys ED-Glas is in no comparison to an achromatic lens! And the negative? It's just a shame that the Svbony doesn't have a 120mm opening. I would buy again!
