SV503 Telescope ED 80mm F7 Doublet Refractor OTA for Exceptional Viewing and Astrophotography
SV503 80mm F7 astronomy telescope SV503 would be better begin for astronomy amateurs to do astrophotography. For those who want to enjoy outdoor activities in the garden.
80mm Ultra-clear Refractor Telescope
A larger aperture means a larger amount of light will get a brighter picture.
ED Lens - Effectively Eliminate Chromatic Aberration
SV503 80ED telescope’s objective lens features an S FPL-51 extra-low dispersion glass ED element, which virtually eliminates chromatic aberration. This results in the good color correction for an ED doublet lens.
Dual Speed Focuser
The gear ratio of the dual speed 2-inch toothed focuser is 1: 10; which makes it easy to achieve accurate focus.
360 Degree Rotating
Deep Space Astrophotography
A thoroughly though-out design and high-quality mechanical components. This very special SV503 telescope provides astrophotographers, visual observers or nature watchers with bright, wide field views when observing starry skies or nature watching.
Easy to focus, light weight, set-n-forget and for the price
I own the SV503 80mm with the 0.8 reducer. The 503 is really a great scope to work with! Easy to focus, light weight, set-n-forget and for the price: I am still trying to find fault with it.
Great Value
The SVBony SV503ED 80mm refractor is a great value and offers fantastic optical performance. For the price of this instrument users will find excellent optical performance. Chromatic color aberation on the brightest stars are barely noticeable and easily handled in post processing. The OTA weight is easily accommodated on light weight mounts such as the Skywatcher AZ-GTi and similar mounts.
This refractor is a bargain that should not be overlooked.
Clear skies...
For me anyway it was money well spent.
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.
So far so good and excellent performance!
I've received the sv503 last week, it really looks like a capable budget beginners scope. SVBONY are producing some nice kit for lower budgets and beginners.
Honestly better than I expected...
It's a solid scope. Make sure you buy it with the field flattener or your edges will be skewed. My stars aren't perfect but that's my fault, plus bad tracking.
The focuser is very easy to use, and very sturdy. It comes with a dovetail and a 1/4-20 mount thread so you can use this on a startracker like SkyGuider or Star Adventurer. I do not regret this purchase, for an entry level scope, it's great.
Also, to the individual claiming this scope has a purple fringe.... it does NOT. Your camera is producing amp glow, getting warm. I have not experienced this issue at all.
Amazing value for the money for both beginners and pros
+ Very nicely made, appreciate the built-in rotator with the tightening screws. I don't see this on telescopes with much higher price tag, it's usually an add-on accessory.
+ Feels sturdy, although I did go through all the screws to make sure they are all tight, a few was a bit loose.
+ The Focuser is like butter, very nicely made, I like the bottom knurled-screw to loosen or tighten the focuser.
+ The dew shield is nice and tight, I had issues with other brands, that the dew shield slides back down too easily. This has just the right amount of tightness.
+Lens is great! (See images) I don't see much chromatic aberration at all. Those who don't know what that is, that lens in the scopes bend the light to focus into your eyepiece and lesser quality lens tend to create this rainbow color halo around stars and shiny objects, because the lights in the spectrum don't exactly focus into a tight spot. This is usually corrected with another piece of lens (those scopes called apochromatic triplet telescopes) , but so is the price go up, way up. For this telescope with only a doublet lens, it's doing fantastic!
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.
Thats indeed a budget-friendly setup.
It’s amazing what you can achieve with the budget-friendly setup.SVBONY have a good range of budget options, worth checking out. This helps to make astrophotography more affordable to a lot more people like me, haha..
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.
