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

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.

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.

Great product. High quality of every detail, everything fits perfectly and is build with good quality materials. I ordered and received package in about 2 weeks to Poland. Delivery to EU included all required VAT and customs - all handled by SVBony. With included in package focal reducer it is possible to make pictures using DSLR. Big 102mm aperture is great for seeing more details and makes this telescope more universal for deep space photography and planets too. Focuser reduces focal to around 570mm for a better DS. Chromatic aberration is much better with ED dublet lenses then in other achromatic products I used so far - not an APO off course but very nice. I can recommend the product, and so far I am very satisfied especially for the price. I also had great contact with the Company handling my request/order.

i have the 503, 102 for a few years now and i really like it, i use it with my asi 585 and it produces images i am happy with for the price of the setup. it seems to be a good match for a smaller censor i think most people buying a cheaper beginner telescope like this are not going to have an expensive apc sized cooled camera anyway. the chromatic aberration is a pain but it can mostly be sorted out in pixnsight.

Great

I wanted a scope to use for astrophotography . I didn't want to break the bank. This scope fills the bill. It's not a APO but you won't hardly notice it in your photos. I'm very pleased with the pictures I've been getting with this scope. If you have extra money to spent, put that money on mount that your buy, that is even more important than the scope. anyway I think it is a great little scope and at f7 a petty fast good light gatherer. If you plan to take pictures make sure you get the .8 field flattner...

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.

I've been using this scope for almost 2 years. Primarily DSO astrophotography with some visual use. I have zero complaints.

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.

I bought this exact OTA a month ago and I tried planetary photography and the results surprised me a lot.

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.

The SV503 telescopes are awesome for this price-range. And especially the 102mm is the best choice for both visually observing and astrophotography.

I own this 102ED myself, and I am planning to add a mono camera and filters ouch instead of getting a triplet/APO

I purchased the 503 80ED last year after having entered into AP and had no idea what a doublet was. I found that the quality was great considering it was my first refractor.

I got this scope a vew days ago. As expected, the quality of manufacturing is at a very high level. Unfortunately I did not yes have the chance to get a first light with the scope, but I am sure it will produce great images. Although, there is a small, but annoying design failure an the focusser in combination with the reducer/flattener. When you unscrew the visual back and attach the reducer/flattener, there is no mechanical stop on the retracted position of the focusser. So it is possible to push the focusser to far into the tube, until the rack and pinion gearing unscrews and the fucousser can fall into the tube! I will make a small 3D-printed washer, to avoid this. Anyhow, good scope! And I hope I can get my first images soon!

I bought the 102 version last month. I'm under Bortle 8 skies, so even my C6 has contrast issues . Yet, the Svbony, under full magnification 200x (using your favorite Baader Zoom and barlow set) at Jupiter and Saturn worked very well.
