SVBONY SV503 Telescope ED 80mm F7 Doublet Refractor OTA for Exceptional Viewing and Astrophotography

I owned a 102/1000 mm F10 Bresser achromat for some time, now I purchased the Svbony 102mm ED FPL51 and its significaltly better with a lot less chromatic aberrations. I like this refractor a lot, especially because it's sold for an excellent price

Visual use is decent. Paired with the flattener/ reducer gives really nice edge to edge images. With a decent cam and filters many nebula images have been jaw dropping. Any concerns I could've sent this back, but am very happy with it, great value deal to be had

I purchased the SV503 80ED in 2024 when it was on sale along with a .8 focal reducer/flattener. The build quality of the SV503 80ED is superb! So much so I rate it higher than the build quality of a $1700 75mm refractor I recently purchased from a reputable online astronomy equipment store. The SV503 80ED with .8 focal reducer/flattener provides nice tight round stars across the field of view of an ASI585MC Pro. It however does suffer from pretty bad blue/violet chromatic abberation on brighter stars. I did purchase the SV231 filter to combat the chromatic abberation problem. I've only tried it once in line with an Antlia Quad-Band filter on the Horsehead Nebula (attached). Integration time was short that night and I pushed post processing a bit too hard and it's not the best representation of what this scope can do. But I did attach other photos as well. Some post processing of the images are better than others. All in all this is a great scope for the money and I'd recommend it to anyone looking to take their first step into astrophotography. Of course with a disclaimer about the chromatic abberation if using a color camera. I have been so impressed with the SV503 80ED I have been seriously contemplating getting the SV550 122mm APO. I'll continue using the SV503 80ED for many years to come as I am sure how well it's built, it going to last a long time.

I have the the 80mm version of this scope. I think for the price it's very good. It's not as good as a triplet but the difference is not big, mainly slight halos on bright stars. It's well built and nice to use. I have the reducer for it as well. It's my go to scope and I really like it.

I have the 102 and the 70 and I love them! Glad at got them before the tariff war being in the states!

This is the exact telescope I use with an ASI2600MC. With a 0.8X FF/FR and a Pegasus Focus Cube, this was the best rig I could afford.

I purchased the 503 102ed during the Black Friday sale with competitive price. Thanks svbony. I can proceed my hobby.

This scope only had a few reviews when I purchased it, so I wanted to add my own opinion for anyone else who is on the fence. I highly recommend the SVBONY ED80. Build quality is great, the dual-speed focuser only needed some minor tweaking, everything feels well-made. Obviously the most important thing is optics, and I give it a 5/5. I waited to write this review until I could use the scope to view a bright 50%+ moon phase. There is little to no chromatic aberration (color fringing) visible; CA is controlled far better than on an achromatic refractor of this focal ratio. If you want an inexpensive mount, take a look at the SVBONY 80ED. This telescope is close to the maximum weight I’d use with that mount, but it works quite well.

I got one sv503 telescope a few months ago. Pretty happy with it.

Beautiful telescope; Focuser works fine when adjusted properly. Once the lens acclimates to cooldown, views snap into focus. Very sharp and detailed; works great with all my eyepieces. Perfect ED starter scope. Very happy with purchase. Try it out!
