I bought this telescope to not only test but to also review. With that being said that brings me to the year 2018 and SvBony. I have been buying SvBony products for a while now because not only are they affordable; but they make some amazing products for beginners and even advanced users who really want to enjoy this hobby.
Now let me talk about the SV25. I have not had a beginner scope since I re-entered this hobby so this was refreshing for me. Upon opening the box I was surprised it came with two decent eyepieces’ a 3X barlow lens’ a diagonal; a nice size solar system map; an adapter to use your phone to take images; a tripod and a nice little instruction book to get that beginner up and running in no time. So this item came with quite a lot of stuff for a really low price.
I was not expecting something more than just okay. To my surprise I was blown away at the quality of not only visual observation but also during imaging. In my mind I was expecting chromatic aberration’ especially when observing or imaging the moon. There was no chromatic aberration what so ever. As most of us who have been in this hobby for a while know that a lot of low end refractors end up having some chromatic aberration.
To me that was a plus that this scope did not produce any aberration. Now let me talk a little about the eyepieces. I have seen a lot of larger telescope companies give low end eyepieces with their scopes as those can be very costly. Both the 9mm and 20mm eyepiece that come with this scope are phenomenal and produce some amazing results during observation.
This is one beginner telescope that is worth every penny. If you’re starting out and want to explore in Astronomy then this is right for you. Now mind you this is a beginner scope. It is a 420mm so it’s a pretty wide field of view so you can see a large portion of the night sky. I do not use my phones camera because I do not have a timer and my phone does not take good pictures.
I also paired this small telescope up with the Sv105 astronomy camera to capture my images because I think it is much better than using my phone.
Overall I am more than pleased with this scope. I wish SvBony was around and had scopes like this when I was only 11 years old. This would have been great for me when I first started out. I will enclose some images of the contents of this package and I will post a couple images I had taken with this scope.
Special note: If you plan to use this to view the sun; use a solar filter on the front objective lens to avoid damaging your eyes and equipment. In my last image you see my home made solar filter.
Pros: Light weight, well built,easy for young children to use (7 and up), good views of the Moon and planets, good views of double stars and star clusters, great value.
Cons: Wobbly tripod. Cell Phone adapter is usable, but limited to the moon, better to get a dedicated camera such as the SV105. Cannot see dimmer astronomical objects, but that is true of all telescopes in this size range.
My Assessment: Good as a beginning telescope for children as long as you recognize its limitations. Let them explore with it, looking at bright objects in the sky (NOT THE SUN!). I would recommend a good book on Binocular Astronomy as a guide to how to find objects rather than a telescope based book as the view from this telescope is closer to that of binoculars than large telescopes.
What can you see: I looked at the Moon, Venus, Jupiter (including the 4 main moons), Saturn (and its moon Titan), Mars, double stars and star clusters. These are great objects for this sized telescope and are easy to find. Bright comets, though I did not view one for this review I have certainly seen them through telescopes of this size.
What you probably won’t see: nebula (this scope is too small), dim planets (Neptune and Pluto)
For it's size it is a great telescope, it is very portable. The only default I thought it had was the tri pod, I felt it was to shaky wasn't able to keep it still enough. I bought another tri pod and it is working great.
I bought this as a gift for my daughter and her family. It will be their first telescope. I liked the fact that it is day/night and has a smartphone adapter.
I find the viewing lenses work fairly well and the scope seems worth the money. I wish the stabilizer worked a bit better at the base connection with the tripod but other than that it works just fine.
