Size: 90mm
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.

This achromatic refractor is a winner. After my 3 star experience with the MK105 I was a bit skeptic but the 102mm sp48 was a different story. It arrived fast and very well packed. The overall impression was that of a well made quality instrument. The focuser worked smoothly. I set it up on one of my equatorial mounts and waited for a good clear sky night. The testing day arrived a couple of days later. My first target was the star Regulus. I used it for a star test. At low power the star looked like a bright point and the intra and extrafocal images looked good. The real test came when I increased the power to 250x using a good 2x barlow and a 4mm orthoscopic eyepiece. The star focused into a nice Airy disc surrounded by a first diffraction ring. This is waht you expect from a good refractor. Collimation was off by just a tiny bit. It was easily fixed by unscrewing a bit the objective retaining ring, tapping around the objective cell and screwing back the retaining ring but just enough for a snug fit. The telscope now showed a very nice collimation at high magnification. On the planets the telescope performed very well on the now small Mars planetary disc. It showed the polar cap and some albedo features. Not bad for an f/6.6 telescope being used at high magnification. Lunar features were crisp and clear. I could not see any violet fringing on the Moon. The star Spica showed very little violet at high power too. The fine focusing knob works great and is especially useful when using high magnification. In recent days I have been using this telescope to observe double stars. It is excellent for this purpose. I have been able to split close doubles easily at powers even above 250x. The telescope has not been tested for astrophotography yet but as a visual telescope this is a very nice instrument for the value. I read that the first batch had problems but apparently they were taken care of. This is a really good one SvBony.

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.

This is an excellent wide-field, low power sky sweeping scope. Very well built! But it is heavy for such an OTA, so buyers need to be aware that a lightweight mount may not be appropriate.
