Should you buy it? - Svbony Zoom 8-24mm Review 

Is the one you bought any good? I'm thinking of buying it.

@Petru Stoian Hi Petru! Thank you for your feedback. It's good to see that you could make the same observations as I did. Clear skies!

@chrisgates4791 Hi Chris, thanks for your input. I'm glad you enjoy the sv171. I mainly use it when Im not observing from home and need to keep things light. Svbony does offer good value items and a lot of them can keep up with more expensive products. Clear skies!

@Rash M Good to know that the 7-21mm version is good as well. I'll have to test it out in the future.

@dimitrihayez6502 Hi, I'm glad I could help and that you like the eyepiece. Not being parfocal is a downside, yes, but otherwise it's a good zoom eyepiece. Clear skies!

@@BogdanDamian I've read a lot about the SV191 on forums but I didn't see any video review so far. Do you think about making one on this channel?

@dimitrihayez6502 I'll try to get my hands on one and make a review in the future.

@MarkMphonoman Thanks for the suggestion. I'll try to get my hands on the Celestron zoom for a comparison.

@@BogdanDamian Actually, I thought I would elaborate on my thoughts a bit about why I would like to see you do a comparison between these two zoom oculars. First, they seem to be close in price and therefore competitive with each other. As budget priced zooms, I am wondering which one presents a sharper image, has more contrast, and which one appears to have a larger field of view. I own a Tele Vue click-zoom 8-24, but would like to purchase an inexpensive zoom for outreach programs. That way I don’t have to worry about it getting abused by observers. Thank you for your fantastic reviews. They have helped me more than once in making purchase decisions. - Mark

@Adrian Rodriguez All Apertura telescopes are made by GSO, which is why they are identical to the ones from Omegon for example. By the looks of it, the Apertura AD series are just like the ProDob series from Omegon. I have reviewed the 12" ProDob and I really liked it. Check the video here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-loPpFGP-Sgc.html Both are great telescopes with very good optics and great accessories. If you have the chance, then definitely go for the ad8.

Hi. I just got a SV135 7-21mm zoom. I have Zhumell filters and they will not screw in. Like it is the wrong thread...metric vs SAE. Did I get a bad one?

@dobdoa3691 Hi! What I've learned over the years of trying out astro gear is that the filter threads aren't completely standardized. Most are m28.5 but the pacing can differ from manufacturer to manufacturer. Sorry to hear that your filters don't fit on the sv135.

@@BogdanDamian Thanks for the info. I just sent the zoom back. Hope it works out better on the next zoom.

@@dobdoa3691 Thread size for your eyepiece is listed as M28.5*0.6

@Andrew Pattie Hi Andrew! Thanks for your input. I completely agree with you. Another reason to get a zoom eyepiece is to use two of them in combination with a binoviewer. Clear skies!

@Andrew Pattie Looking to sell your Hyperion zoom by chance? I’m in the market for a used one.

@Joe Pona hi m8 sorry but I'm keeping it as I use it lot in my travel scope however depending on ur scope and needs think the svbony is a good choice 24/8/8/3 will cover basically everything and both will cost u less u could even and the svbony 68° set of 4 and it would cost u around the same 🤷‍♂️ as the hyperion zoom and Barlow clear sky's m8 hope u find one if that's what u want

@@andrewpattie358 appreciate it man. Clear skies!

@user-nn2ni5nq1x Hi! I don't believe there is an adapter for for using the eyepiece in combination with a Canon camera unless you 3D print it yourself. I would, however, recommend attaching the camera directly to the telescope with a T/T2 adapter ring for Canon cameras like this one: www.amazon.com/Starboosa-Variable-Extension-Telescope-Adapter/dp/B083DDPN4W/ref=sr_1_3

@ForzaInternazionale9 Hi! If you have the possibility, then get the DeLite from Tele Vue. In my opinion it's one of the best eyepieces for planetary on the market. If you already have a 2x Barlow, then go for the 9mm version. Otherwise maybe try out the 7mm. If money is an issue, then go for the Hyperion instead of the Morpheus. It's very good mid-range eyepiece and you'll get the same image quality as with the Morpheus, but only with a smaller apparent field of view. The extra field of view on the Morpheus is kinda waisted when observing planets because these appear relatively small in the night sky regardless of the magnification. Hope this helps.

@@BogdanDamian Thank you for the response Bogdan. I took another look at everything and actually decided to go with the 4.5mm Delos instead because I feel the Barlow diminishes the view so I'd rather just have something very strong for planetary observations.

ForzaInternationale9 Great choice! The Delos is a great eyepiece. Let me know how you like it.

@@BogdanDamian The Baader Morpheus range are far superior optically to the Hyperion range. This isn’t just my opinion, but the majority of users of them both.

Olá amigo … sou do Brasil ,e também novo no ramo poderia me dizer se posso usar essas oculares zoom com barlow ?

@sniperthief1110 Yes, absolutely! If you start with a good zoom eyepiece it will give you some amazing views of the night sky and allow you to learn this hobby better with minimal costs. Later on you'll have a much easier time deciding what you like about astronomy and and in which direction you want to go with the setup. It's going to be easier to decide about which fixed eyepieces to get. A good zoom eyepiece will also make for the perfect travel eyepiece when you don't have the space to carry everything with you. The Hyperion Mark IV Zoom from Baader is one of the best options if not the best one.

@@BogdanDamian Thank you

@linou1986 Hi! It really depends on you budget. The mark IV is the better zoom eyepiece, no question about that. But it's not by much while it costs 3 times more than the svbony. The only real downside of the svbony is the narrower fov at the longer focal length settings. In terms of brightness, contrast and sharpness the difference between these two aren't big at all, maybe 10% or so in favor of the mark IV. The mark IV also has the advantage of being part of a well though out Baader modular system, where you can get a lot of accessories compatible with each other. This also is something worth considering. If the budget is tight, than go for the svbony. If money is no issue, the god for the mark IV. Hope this helps.

@@BogdanDamian thx you bogdan .you always answer me that s Very kind of you! So it will be thé mark for me!! I bought also a focuser ts optic monorail 96 2"

For my 120 600 sw

@Brian Lopez Hi Brian! Out of the two I would go for the sv191 9-27, but better still would be the sv191 7.2-21.6. It offers a wider AFOV and longer eye relief than the 9-27. The 7.2mm focal length combined with your telescope will also offer a decent 138x magnification which is good for planetary observations.

@@BogdanDamian I wanted to go woth sv 191 7.2mm - 21.6 but wasn't sure if my small scope could handle the magnification if I barlowed. I'd prefer that one as well so thank you so much for the response. FOV is so important

@@BogdanDamian my apologies but do you think I can use a 2x barlow on the 7.2mm from the sv191. I believe that's a little bit over the max of the scope. Sorry to bother but just want to make sure I can get the most out of my limited budget. Thank you

@Brian Lopez Hi Brian! No worries. With a 2x Barlow and with the eyepiece set to 7.2mm the resulting magnification will be 277x which is above the maximum theoretical magnification of your telescope (228x). So you are correct. In this case it will be too much. But the nice thing about a zoom eyepiece is that you can manually adjust the focal length. In your case, every time you want to use the Barlow you need to set the eyepiece to ~9mm to max out the telescope. Below that you use it without a Barlow. The advantage of the 7.2-21.6mm sv191 is that, compared to the other zooms, it offers more useful magnification range (for planetary) where a Barlow is not needed. If you have a high quality Barlow that all this doesn't matter, but if it's less than perfect, then the use of a Barlow will reduce the image quality a bit. So avoiding the Barlow might be a good idea. Hope this helps.

@@BogdanDamian makes total sense. I didn't know you can shift the zoom eyepiece like that so makes total sense. I ordered the 7.2 today abd can't wait to get it. Thabks again for your help. Your videos are so helpful for us newbies. Now I gotta look into a barlow as I only have the one that came with my scope. Much appreciated :)

@NaMano Yes, it works without a problem. Depending on the Barlow, you can even unscrew the bottom lens of the Barlow and attache it to the zoom eyepiece for a better usability.

Thank you, I am getting a skywatcher 6 inch dob 150mm, so hopefully it all goes well seeing some of the planets. Do you know if it is a good beginner telescope? will it see Jupiter, Saturn and maybe some galaxies I’m not sure, kudos for helping me out.✌️

@NaMano The 6" Dob from Skywatcher is definitely a good telescope. Observing planets and DSOs with it won't be a problem at all. As long as the weather allows it the telescope will be able to provide some really nice views of the night sky :)

@@BogdanDamian sweet

@Rober Henry Malpartida urquizo Puede ser que una lente no esté pegada a la carcasa. Pero esto no es malo. Tengo un Panoptic de 24mm que también hace esto y funciona perfectamente.

I not noticed much in mine. I have the 7-21 and it's great. Telescope is a 114x900

@Dragos Marinescu Hi Dragos! Thanks for your input. I aslo think that Svbony has the potential to establish themselves as a leading brand for affordable astronomy products. I'll have to test more of their products in the future.

It's all about the personal experience. I have the Morpheus 4.5, 9, 17.5, and the Hyperion mark 4 plus its barlow. The experience with the Hyperion is kind of meh... I use it only between 8-16mm, only because of comfort, not having to change eyepieces. Beyond 16 the field of view is significantly diminished. Using its barlow is worse than meh... So, if you can enjoy a 7-21 svbony, good for you, for me it's a waste of money. I tend to go for the Hyperion Mark IV (without its barlow), a televue 2x barlow, and a Nagler5 31mm, that would be enough for me (keeping the 9mm and 25mm that I already have). If you cannot enjoy viewing through a 900euro eyepiece because the price hurts... well, everybody hurts... let be this one the only one...

@@florinenescu2837 900 euro ?! Can you see GOD with it ? You are just ridiculous. Hope you meet HIM soon, in person.

@@dragosmarinescu5520 ​Save your money; you'll not find a better Moon and Planetary Eyepiece for your Mak than Svbony's SV135 Zoom. @21mm it should display the entire Moon and @7mm it will push the Mak to just under its maximum power. The only other EP worth picking up for your scope is a fixed 24mm 68° EP (or a 32mm Plössl if your budget is tight) for widest field of view. The Zoom and wide-field EP will show you everything your Mak is capable of.

@@florinenescu2837 The Morpheus (which i own) are overrated, they have a yellow tint that becomes more illuminous yellow the brighter the object. Try it on a sunny day, the image is so washed out the view is almost invisible, my Celestron X-Cel LX (which i own except the 2.3mm) has a neutral view and shows more detail, narrower field of view but excellent eye relief. No one talks about the kidney beaning or astigmatism in the Morpheus or the slight chromatic aberration and the blurry edges. My APM 100 degree Eyepieces are also nuetral in view but sharper, the eye relief is less but you can pull your head back which reduces the field of view slightly to increases eye relief. The SvBony 7-21mm was the only zoom eyepiece i recommended to people, now i also recommend (budget allowing) the SvBony 3-8 zoom, its on par with the Televue zoom but a fraction of the cost. These 2 zooms, after my comparisons with other zooms makes these look either under priced or the more expensive ones over priced. These are in F5 and lower telescopes where the biggest challenge is coma in a Newtonian or Chromatic Aberration in a Achromat telescope. High focal ratio scopes, almost all eyepieces look perfect. A 31mm Nagler is huge, sticking it in a long barlow is crazy, that would stick out to something like 30cm, even on big dobs that would be so uncomfortable its not even funny but each to their own. The 28mm William Optics, also sold under Nirvana, Astrotech and others are a fraction of the price, slightly less field of but has about 95%+ of the quality. However, your biggest issue is your attitude. Not everyone can afford high budgets for marginal improved views like those of us who have, most people have more important things to focus on and its more important to encourage people to become astronomers, not try to push them away with arrogant attitudes like "mine is better than yours so give up unless you spend obscene amounts of cash on equipment i like" because that is exactly how you come across. You can achieve fantastic views with budget equipment, the objects we look at wont explode and don't discriminate like some pompous gits in this hobby who care more about equipment than the sky, all that matters is that people are content with what they have and see. People like you give this hobby a bad name.

Your scope does that not the eyepiece.
