The weather, new software, learning curve have limited my use of the scope to date, but I am eagerly awaiting for clear skies!
Purchased the SV503-102ED after having excellent results with the SV503-70ED. Smooth 10/1 focus. Sturdy tube and mounts. Snug dew shield retention. Great black anodize finish on optical fittings. Fittings have compression sleeves. Optics are good even without the field flattener, having only minor star stretching at the edges using a APS-C crop sensor. The 70ED with an APS-C crop sensor allow for 3 degrees (or 6 moons) field of view. The 102ED with an APS-C crop sensor allow for 1.5 degrees of view. Would buy again.
Very happy with it, a good investment so far. I have the 80mm ED one with the 0.8x focal reducer, and the few pictures I have taken so far look stunning. I would highly recommend the field reducer/flattener since in my case it really improved image quality at the corners.
In the pictures below I used a Canon EOS T6i, with the scope mounted on a Skywatcher Star Adevturer 2, a very lightweight and portable setup.
Plusses :
* Rotating focuser is extremely useful, both for visual and astrophotography framing
* Excellent optical quality due to their use of quality Ohara S-FPL51 glass
* Butter smooth dual speed focuser
* Overall great design with lots of adjustment and mount points
* Included slide-out metal dew shield
* Mount points for electronic focuser
* Standard 2 inch (48mm) filters thread right into the front of the 0.8x focuser, with no adapters needed
Minuses :
* The top aluminum handle should come with it.
* Instructions are sketchy regarding for ex. on the use of 12 adjustment grub screws on the focuser.
Some additional suggestions :
* Get the 0.8x SVbony field flattener, it greatly improves sharpness in the corners !
* Get that red aluminum handle, it helps carrying the scope, and also can be used as a mount for a finder.
* Most likely, if you do astrophotography, you might need M48x0.75 extension rings for proper 55mm backfocus on dedicated astro cameras such as the ZWO, Risingcam etc.
* For the Canon EOS EF mount, the correct T2 adapter is the SVbony SV195 58mm, available here for $12. No additional rings needed there !
Five stars so far !
Well made OTA, pairs perfectly with my AVX mount. Dew shield helps, but on humid Arkansas nights still needs a bit more prevention. Focuser beats my one on my Newtonian. Would love to see them make an SCT with this build quality.
This is a very well built tube assembly. The quality and design of it are apparent. Its image is on par with my 6 inch f/6 meade refractor in the preliminary use I have done. It’s size makes it a very good choice for a large spotting scope I will use it for once I find a suitable tripod. I have used a 20mm Pentex wide field eyepiece with a Pechan/schimdt image erector that has a wide aperture. as well as a 38mm Erfle eyepiece yeilding a large flat field. This will be a very good Rich-field telescope.
My first telescope and I’m happy with my purchase!
This is for the 102ED. I viewed the March 28th, 2022 conjunction of the Moon, Venus, Mars, and Saturn and I am happy to report that I observed no false color. I used a 13mm DE Lite for 55 power. It seems that the "ED" designation really means something, at least in this case. By the way, I mounted it on a Versago II mount and it works great. The build quality seems fine and the focuser works smoothly, although I was unable to reach focus with a barlow lens. The finder mount advertised with these scopes was easy to attach at the screw points.
Well built product. I couldn’t be happier.Performs as expected with all the added features you need for an astrophotography rig. The rotating focus assembly is a nice touch. Construction is solid and high quality. Optics are better than expected. There are plenty of options for accessory mounting. The only thing I would like to see is a handle mount for this telescope (102mm) much like the smaller versions have.
Didn’t know how good it would be but watched a lot of YouTube videos so gave it a shot and was impressed!
I own several telescopes and ended up buying the SVBONY503, 102ED because of the many good reviews and because I didn’t yet have a scope in that focal length range. It’s a solid, well-built scope and I like the feature that allows you to rotate the focuser end so you can easily frame your images.
For my first two nights with the scope, I imaged the Rosette Nebula with a full spectrum modded Canon Rebel T3i and was very happy with the results with just over 4 hours of imaging time. I’d recommend this scope whether you’re new to astronomy or have been doing it for years.
I have numerous SVBONY accessories I’ve purchased over the years and am happy with them all. I’d love to see another scope like this with a focal length in the 1,000 – 1,200mm focal length range and would definitely buy another scope from them.
I ended up being surprised by how good everything looked through this telescope. With good eyepieces, there is literally no chromatic aberration visible and the image is sharp from edge to edge. Also, the build quality of these telescopes is amazing. Highly recommended!
The focusing controls operate smoothly. The lensing produces excellent images with no observable aberration.
Really liking this scope! Don’t expect to se footprints on the moon or incredible details of Saturn’s rings but you will definitely see the Saturn and it’s rings, moons of Jupiter and it’s clouds. Keep in mind picture of the moon I attached was taken on my phone and scope was mounted on wobbly tripod so it’s came out pretty bad haha. Now, I’m a beginner but wanted something better after trying few scopes and doing a lot of research and I’m satisfied, and I think I will be satisfied for a while lol it’s just matter of good tripod. Don’t expect to buy this scope, put it on $100 tripod (even if it claims will support the weight) and hope it won’t wobble. Don’t make my mistakes haha. Expect to purchase nice mount and you will get a good image through eyepiece in return. Didn’t try it for nebula yet, as still exploring planets with it, trying out different eyepieces/filters.
This takes great photos and is very well built.
it does a really good job at getting round stars. I haven’t tried many other lenses and scopes for astrophotography to compare to, but I can say this scope did as good of a job as I’d want it to while having specs of scopes costing hundreds of dollars more.
Amazing telescope. Built like a tank, all metal parts, amazing views. Don’t hesitate!!
Great telescope. Stars are crisp and clear. Very sharp focused. Very,very nice.
This is a pretty sweet scope. This is my first real refractor telescope and it does not disappoint. I shot the attached images with a ZWO ASI533 Pro color camera. It should be noted I live in a Bortle Class 7 region and was still able to get some amazing photos. Focusing is smooth as butter and I love I can finely dial it in with the two stage focuser. This is a hell of a scope so if you’re on the fence…grab one! Also get a decent equatorial tracking mount because that is a must when doing astro imaging. Have fun and clear skies!
Great Telescope! Mechanics, quality, appearance are beautiful! Jupiter managed to look in the cloud window, the picture is just gorgeous. There is no chromatism.
Useful features included with the scope are many, well thought out and very well constructed. Views are awesome and crystal clear. I am more than 100% happy with my scope and can highly recommend it.
Great color rendition. Scale on back focus tube makes it easy to find focus next night. Entire focus back of scope can rotate giving operator the ability to format every picture accurately. DEW shield nice and long also helps shade from neighbor lights.
Highly recommended!
The scope is very well contructed and the optics are indeed sweet. I wanted a small telescope to use at home as well as on the road. This is a scope that can make cheap eyepieces like plossels look great and more expensive Naglers look fantastic. I’m sold and look forward to years of great seeing. Thanks for a really good telescope.
This a well constructed piece of equipment that has the clarity of a larger scope. The optics are fantastic an extremely clear I was impressed with this the first time I had taken it out and looked at Jupiter with several of its moons. I would recommend this telescope to the beginner and novice astronomy enthusiasts.
I’ve been an amateur astronomer for 40 years, and currently own 7 scopes, most of which are Schmidt Cassegrains that I use for deep sky observing. Bought the SV503 102mm as a ‘cheap’ alternative to the scope I actually wanted, which was selling for twice the price. Let me tell you that I couldnt be more pleased with this scope. I own an 80mm triplet APO, and I cannot discern any chromatic aberrations that diferentiate the SV503 from the higher-priced Apochromatic scope. I tried the SV503 with several high-end plossl, nagler and zoom eyepieces, and none drew out any significant optical imperfections or refractory aberrations, even at the edge of the viewing field. -Especially shocking given the FPL-51 glass versus the more expensive FPL-53 glass used in most high-end refractors. The SV503’s dew shield transitions to the extended position smoothly, and tightens when extended to lock firmly in-place. -Not the typical stiction Ive witnessed with dew shields on other budget-friendly scopes. The focuser is quality, fluid and precise, and the hardware is sturdy. I suggest you also buy the appropriate field flattener (SV193) if you’re planning on using the scope for astrophotography. SvBony has done an excellent job with this scope, and I wouldnt hesitate to recommend the SV503 to anyone.
