A few features to look for in a Spotting Scope: • is it waterproof; else you'll find the lenses fogging in wet or cold weather? • is there a sheepskin cover available; as this'll also reduce fogging when you take it out on a cold wet day? • scopes with an angled eyepiece (like this one) are much more useful than cheaper ones with a straight eyepiece. • the "sun shade" is actually more useful for stopping rain getting onto the lens and ensuring your view. • zoom Spotting Scopes like this one are more expensive than those with interchangeable magnification lenses; they're also more likely to give fogging problems is the seals on the zoom knob dry out.

Been debating between this one and the SV41 (Or Visionking MAK equivalent). Would you recommend going with MAK models or this one? I hear about MAKs needing collimation down the line and possibly not being able to and whatnot, but is that true? Would you have any suggestions? Seeking a jack of all trades with maximum portability so both seem appealing, although the MAKs seem shorter
hi, thanks for watching the videos. We didn't keep the scope, it was for sale on our website. we made the video some time ago, from memory I think we checked the scope at about 80 yards.
I bought one recently. It’s okay, but in high contrast views there’s a *lot* of purple fringe. Looking at the moon there’s enough chromatic aberration to drown an elephant. For birds, target shooting, spying on a sun-bathing neighbor - it’s not bad. (I live in a community of mostly retired folks, so… no sun-bathing hotties for me to look at.) Cost me about $50, so for the price I can’t complain, but I do wonder if the purple fringing is common, or if mine has something wrong with it.
There is a simple trick you can do to reduce the purple fringe on your scope. The purple fringe is called chromatic aberration (CA). CA is an issue that all refractor scopes fight against (with a financial cost). *THE SIMPLE TRICK:* Make yourself a lens cover with a large hole *in the direct center.* You can use duct tape and cardboard, or even custom made plastic from a 3D printer. The loss is less light gathering with the cover on. If you made a 35mm hole in your cover you turned your 70mm into a 35mm objective lens. What you gain is a slower focal ratio (F/) (which is one way to reduce CA). Higher number = slower F/. *MATH of EXAMPLE:* I don't know the focal length of your scope so as example I'll just pretend it is a 320mm focal length. The equation is focal length / objective lens. So we go from 320 / 70 = F/4.57 to (with the cover on) 320 / 35 = F/9.14. This would really reduce the purple fringe for your views of the moon.
Axtually youd be surprised. Someone did a review on a vortrx uhd spotting scope that was in the 800 bucks price range. It also has purple tinge on certain objects. But not every time. I'm assuming light , atmospheric conditions, temperature has something to do with it. So ED glass helps get rid of the purple tinge. But its not as clear as a spotting scope without ED glass. So I'm also gonna assume theres more coating on the lens to help deter purple and other chromatic issues at the cost of clarity. Like eveything else.. Give and take. There can never be 1 perfect thing. And if there is. It'll be more expensive to the point its pointless😂
For full screen phone view install on phone lens clip makro mini ocular = phone->macro glass->telescope = full screen & x2 like barlovs pro telescope zoom lens.
@@longbows It says that the svbony sv 28 25-75x70 telescope has a 75x zoom, but in the videos I watched it is not that high. How much do you think it actually zooms

Thanks for the input.
I bought this for the Green Comet and sighting in my rifles and Ship Watching . I have not received it yet and can't wait to use it .
I hope you enjoy.

Hey, thanks for the review
Our pleasure! Did it help?
Great stuff, thanks for sharing!
My pleasure! Hope it was useful

How is the scope holding up after 2 years? How far were you able to see your targets clearly? Thanks enjoyed your video.

For cheap optics like this I'm not surprised. No optical equipment under $100 will have perfect optics.

Hello, I can guess that this telescope does not really zoom 75x, but how many do you think it actually zooms
O que você pode me dizer sobre o SV401 em comparação ao SV28?
For full screen phone view install on phone lens clip makro mini ocular = phone->macro glass->telescope = full screen & x2 like barlovs pro telescope zoom lens.
Thanks for that. Big Amiga fan here too!
The ring on the eyepiece is for zoom only from 25x to 75x.
Is this the same as the Avalon 70mm scope just rebranded?
Hi, I don't know, perhaps contact the maker of this one, SVBony and see what they say.
Hello, does this telescope show long distances such as 20-25 km
hi, no, it's for sport 'spotting'. you want a more specific telescope, find a local shop if possible
Doesn't it show that far distance
the horizon is only about 3 miles. this isn't designed for that sort of distance, it's for archery.
@@longbows It says that the svbony sv 28 25-75x70 telescope has a 75x zoom, but in the videos I watched it is not that high. How much do you think it actually zooms
I would ask Svbony, I only use it for spotting at 100 yards as per video
