SV48P Telescope, 90mm Aperture F5.5 Refractor OTA for Adults Beginners, Telescope for Adults & Beginner Astronomers, Telescopes for Deep Sky Astrophotography and Visual Astronomy

Excellent quality and finish. Probably the best 90mm achromatic and at a special price. I tested it in Orion and Pleiades with Arcturus binoviewrs and the image quality is very good. In Sirius you can see a small blue halo depending on the position of the eye in the lens, but nothing bothersome. For price, quality and comfort, you cannot demand more. Updated. I preordered the sv48p 102 on August 1st and received it yesterday, the 26th. Very well packaged and with the promised items. For the moment I was pleased to be able to unscrew the lens and appreciate it better in my hand. I find the focuser very similar in hardness to the 90mm SV48, but in the 102mm it does not have any type of play when extended. In that sense it is very solid. The 90mm is good, after some simple adjustments. I manage to try it soon, I will express my personal opinion. I hope to carry out the test together with my 90mm sv48p, which with the sv231 filter, demonstrated good results on the Moon, Saturn and Jupiter, the latter showing very well its two main stripes and slight tones in both hemispheres with minimal chromatic aberration at 124x. I will also make a comparison with a Skywatcher ST 120mm. Compared to the mak 105, the sv90p showed a sharper, clearer and brighter planetary image at similar magnification with the sv231 filter despite being an achromatic. The mak is excellent at higher magnifications and with regular "arcturus" binoviewers, especially on the moon. The 90mm is excellent with linear "founder optics " binoviewrs and svbony 25mm plossl and svbony 15mm redline. August 28/24 102mm first impression with Saturn. Really bad weather. Practically 90% cloud cover and bad seeing. Without the filter, in the few moments that the weather permitted, I was able to test at 111x. Very defined and good shine with the SV Red Line 6mm. Then with the barlow sv achro at 222x, still with defined color in the planet and shape. The atmosphere did not allow me to detect chromatic aberration at the time. What I can conclude at the moment is that it has a good lens and its coating is very good for Saturn without needing to use the filter. August 30/24 Overnight test. 90mm and 102mm. Eyepieces, sv135 zoom, one for each. 6mm red line, 8mm starguider, sv82a blue filter, sv achro 2x barlow, sv231 filter. Saturn. Both telescopes provided a clear and sharp image. sv90mm, showed slight but not intrusive chromatism, while the sv102mm I could not find any aberration. Test under different magnifications. Jupiter. Both telescopes showed chromatic aberration even with the sv231 filter and both showed almost the same basic details on the planet, but little advantage for the 102mm . The image with the most contrast, although smaller, was the sv90mm with the 8mm starguider and the blue filter. The clearest and most comfortable image but the lowest contrast was the 102mm with the 6mm redline and the blue filter. The atmosphere today also played its role and did not allow the greater aperture of the sv102 to be taken advantage of. I also took photos with my cell phone using the SV UHC and UV/IR Cut filters. Which I recommend for both visual and occasional photos with your phone, both providing better details for example in Orion. In short, if you are looking for a quality refracting telescope at a good price that can do everything well even if it is not excellent and you are only going to use it occasionally, it could be either of the two. Although it could also become your telescope for life. Don't forget that, with the same quality, there is no substitute for aperture. Svbony has achieved a very good 102mm fast achromatic with excellent chromatic aberration control.

I don't like the way the focuser works Not really worth all that money I spent. I can't believe messed up the focus or is you can tighten up the screws to get the sloppy out of it. But then the focus was too tight to turn and when you get it to turn, it feels like it's grinding or something. It's really weird feeling. It's not smooth at all like a cheap skywatcher

I give the 90mm 4 stars, with qualifications. You have an inexpensive, but solid entry level telescope. It is well built, but the focuser usually needs some massaging to work reasonably ok. The glass is nice, but it is an achromat: point it at something bright and you will get color at the edges,ymmv. However, put in a nice wide eyepiece and point it at some star fields, and the 90mm's wide FoV shines. It's focuser usually jumps, but it is strong: it handles my 2" 28/82 easily, and having a two speed is something not usually seen on a scope in this price range. This is my fourth sv48p; one is now my Grandson's, and one became a gift. It's flaws keep making me let them go, but it's charms keep bringing me back. Look for a sale. At list, it's a so-so telescope. At a Black Friday sale price, it suddenly becomes a much better performer.

I really like SVBONY products, I got to try many of them from binoculars and eyepieces to telescopes. They usually offer really decent stuff for a bargain. This one is no exception. It's just an achromat but it offer nice optic performance, really bright and sharp views on the center of the FOV. Being a relatively fast scope it offer really wide field of views, with a WA low power eyepiece you're able to see the totality of Andromeda galaxy. So yeah, for wide views it's a really good grab and go telescope, it's quite short and not that heavy even for it's completely made of metal construction. Nice complement for a long focal length scope that you might be using for planetary and lunar views like an SCT. Regarding to the complaint for the loose focusing tube, you only need to adjust one screw and you're pretty much over it, you can easily find tutorials on video to fix this issue

This telescope is a bargain! I don't claim to be an expert but I did build my first telescope sixty years ago and have owned a few along the way. I have a much larger Celestron SCT but its a job moving and setting up just for a quick causal view. I wanted something reasonably priced that would be small, light and easy to move and set up. I paired this scope with an Explore Scientific Nano tripod and a right angle aiming scope and now have a very competent grab-and-go set up. My particular scope is very sharp for something in this price range. I use various eye pieces on it and it gives great sharp views with a wide range of eyepieces. For a quick and simple session I can set it up with a 8-24mm zoom eyepiece which gives it a lot of flexibility. Yes, a scope costing three times as much will give a tiny bit better views but most will notice little to no difference. I would say to step up to a set up to the next level of performance you will need to spend many hundreds of dollars more, both in the scope and the mount. So, in short, this is a good quality scope that will give you great results while not breaking your bank account. I find myself using it more than my "big scope" as it gives great views, easy to set up and it was "cost effective". A great buy and much better than those kid's toy scopes that are only a little less expensive but don't off near the performance This makes a wonderful entry level scope that can grow with you and give you years of service.
