What’s UP with SVBony’s new SV48p Telescope?

[@shortexposureastrophotogra4988]

Thanks for making a good review. My experience with the same scope is similar. Your new lens may be better than my new lens, but mine is definitely better than the original. I'm hoping for some good weather to check it some more.

[@johnkory9042]

Great Video!!! I bought a 48P about three months ago... At first i thought it was ok but the more I pushed it the more I came away disappointed with it. Star images were spiky and when in far out of focus there was a huge coma image. I pretty much gave up on it and started using my 6" short tube reflector to take it's place. I figured i would use it for terrestrial use during the daytime. Then i saw your video and decided to give SV Bony a jingle... they asked me to describe the trouble i was having and they agreed that the objective lens was faulty. They are sending me a replacement objective.... Looking forward to seeing what this scope can do with proper optics!!!! Thank you for posting your video!!! Stars, Cars & Guitars

[@AmatureAstronomer]

Nice. Been considering this optical tube. Might consider picking up an SvBony SV231 color correction filter. When used with the Sharp Cap Pro color correction feature, it eliminates purple fringing entirely.

[@LearnToStargaze]

Gah! You are right! I actually think they may have sent that to me a while ago and I forgot to include it in this video! I’ll have to look for it.

[@scottm599]

Cool video! Would love to learn more about the introductory imaging approach that you are using.

[@LearnToStargaze]

Thanks Scott! This approach is really only for planets. 🪐 An ASIair and a planetary camera can be used with any telescope setup.

[@scottm599]

@@LearnToStargazeThanks, John. Wondering if I should give this a try using my scope that looks out through the back window. I imagine low probability of success, but wouldn’t it be great if it worked to some degree?

[@LearnToStargaze]

@@scottm599 The Seestar S30 might be less expensive than the planetary camera alone and planetary imaging is really a finikey process. It can be fun though. Just depends on how much gear you want to accumulate.

[@davidwitt2188]

Forcing your customers to replace the objective lens on one of their flagship telescopes does not build my confidence in this brand. Why wasn’t this caught by quality control before it ever started shipping?

[@LearnToStargaze]

I thought that as well. QC needs an optical test stand to check the lenses.

[@jimpoop]

It is a little disappointing, ive looked through one of these and it wasnt bad, though not excellent either... for 300 bucks it wasnt bad, ..but at least they are correcting the issue, also, I would consider this one of their lower end or intermediate scopes, I'd say their 120mm triplet is their flagship.

[@dlrager]

The 48P line is their low end, not the flagship. The SV550 is their flagship line. I've had the SV503 80ED and it was excellent for the price. Used it for the eclipse in April. Have the SV48P 90mm and not as good as the SV503, but for the price, I'm not complaining.

[@mark2220]

First this is a low end scope, not even a higher tier from SVBony.. and two, you have to give it to them, they absolutely stand behind everything they sell and will make it right. I'll take that any day over some other budget companies..

[@robertsonsid]

It would be neat to test the old lens. I had a 90mm objective that had poor images until I found out one of the components had been flipped by the previous owner. I had a 60mm lens that I had to rotate the components to improve the image. Pinched optics is often an issue as well that can be fixed by loosening the cell holder and tapping. Of course, in your case it sounds like SVBONY was aware of the issue.

[@A0111.]

It looks like the lenses are cemented together, so I don't think it's possible to rotate them.

[@keithpratt2026]

Excellent video. I started to get this scope; instead I bought the MEEZAA 80ED. It has a near-perfect lens, the focuser is the same as the SvBony 48P f/5.5, and the cost was very reasonable. I may go back and buy this one later. I also have the SvBony SV48P 90mm f/5.5 that is very good. Excellent telescopes for not a lot of money!

[@LearnToStargaze]

Thanks!

[@LearnToStargaze]

Yes, this does not have ED glass, which makes a big difference for photography (you can see the halos on the stars in the Orion images). Your 80ED would have much better performance with a camera.

[@confidentstreetlamp1762]

Hi I’m looking to get a variable polarising filter for my bday. Do you think I should get the 1.25 Svbony one or the “astro essentials” one from firstlightoptics?

[@LearnToStargaze]

I’m familiar with polarized filters, but what’s a variable filter? Are there two and you twist them to control the amount of light that gets through?

[@confidentstreetlamp1762]

@ yep that’s exactly what they are. I really need it for Jupiter and the moon since my heritage 150 is soooo bright

[@sat.aviation]

can you make a guide on the best cameras and stuff for a 16 inch dobsonian?

[@LearnToStargaze]

I don’t think I’d want to attach a camera to a dobsonian that big. Do you have a tracking wedge?

[@Yelnats101]

that scope on a track mount would be a good setup. im thinking of buying it so i can do some long moon recordings, video recording for a student project

[@LearnToStargaze]

Nice!

[@A0111.]

Fast achromats like this one are NOT good for the Moon because of significant chromatic aberrations. Look for f10 refractors like 102/1000mm, or 90/900mm as a cheaper alternative. You can still fit the whole Moon with APS-C camera and a 1000mm scope.

[@LearnToStargaze]

@@A0111.FALSE.

[@Yelnats101]

@@LearnToStargaze i have heard that said. People say it’s not good for this or that. Been then they show evidence showing it’s great. I’m still looking to build a new setup. I have had my astromaster 114eg for about 12 years now. It’s a great scope if your patient and take time to learn how to use it. Just need an upgrade. I have also thought about putting the 114 on a tracker. Stick with what I know that way. Undecided. Open to suggestions

[@A0111.]

@@LearnToStargaze Laws of nature: for achromats the shorter the f-ratio the more prominent chromatic aberrations are. As per the chromatic aberrations chart for achromats, for 102mm of aperture there are minimal or no chromatic aberrations at f=12, i.e. 1224mm of focal length - that's why people buy APOchromats if they need shorter focal length, but for the Moon, and to not break the bank, it's reasonable to go for 102/1000 or similar. I'd really like to see how this 102mm sv48p works in deep sky narrowband imaging though.

[@eottoe2001]

Thanks for the review. I've been thinking of getting one for a first serious scope. The sooner the better with the Tariffs coming. Could you cover mounts, please?

[@A0111.]

It's better to get any dobsonian as a first serious scope, at least 6", better 8". Actually, I just sold my 8", because I know I can see more with my 10". This 102mm SV48p is more like a 2nd "grab&go" scope, or an introduction to astrophotography.

[@xuanbach1249]

Great replacement, i've same result when bring the sv48p 102 outside

That’s basically covered in “A Telescope for Every Budget” but it’s a good idea. It really depends on what you’re trying to see.

[@AdamUSA-wu5cs]

If I got mine last week, would it be accurate to say that it was shipped with the correct lens?

[@keithheuston8630]

How do you feel it compares in quality to the Omni 102 AZ?

[@LearnToStargaze]

Same optically, but far higher quality focuser, tube, and bracket.

[@JoepsAstronomy]

For the price you can hardly complain, but getting such an astigmatic lens shows very poor quality control and this should have never been sent, or screwed on a tube. Additionally when you get a completely different lens something doesn't seem right: either they used the wrong lens, or changed the design. Either way: bad QC. Overall I'm pretty happy with SvBony with some products, and after your lens replacement I'd say the performance was on point for the price.

How does it compare to Celestron's 102mm 6.5? Is the different focuser that much better? Optics and coatings? $300 for the Svbony OTA vs Celestron's complete "Costco" 102 for $270...?

[@LearnToStargaze]

The optical performance may be similar, but the SVbony is more robust.

[@A0111.]

My Celestron 102 has some pinched optics, or it looks like pinched optics because I wasn't able to fix it by loosening the retaining ring. As for the improved version of SVBONY 102mm Sv48p, there's another video on KZbin where new lens cell was installed, and the optics still aren't great. Actually it's worse than my not perfect Celestron. I'm starting to be afraid of refractors.

[@omaralmeidarg]

I bought the SV510p for R$400, Brazil. This SV48p costs $225 in the US, much more affordable for astronomy. And one question: What app did you use on your phone? And what comes with the planetary camera?

The app comes with the ASIair. The astronomy camera comes with a USB cord and a few adapters.
