Very doubtful concerning zooms but after your review, and the mention of price, decided to give it a go and purchased the 21 to 7mm. Used it last night with a Startravel 80. Very impressed, particularly as I did not have to alter focus going through the range. Colours seemed o.k. as well when swapping with a 21mm Baader Hyperion. With a 2x barlow impression was the same. It will come in handy for doubles and planets on my 200mm reflector. Always a bonus to think money has not been wasted. Without your review I would be none the wiser. Thank you indeed.

Good review Ruz, I enjoy watching your channel! I'm more of a visual guy myself who enjoys taking images now and then. Personally I like the prime (fixed focal length) eyepieces because they are lighter and have much wider field of view. The Svbony red line EPs are almost 70 degrees and individually smaller, lighter and under £30 each.

AstroFarsography

Thank you Zarkuon, I'm glad you enjoy my content. I don't think I have many mainly visual users who watch my content especially as it's mainly geared towards photograph. Agree primes have a big place to be, lighter and such so I can imagine as a visual yser the SV171 isn't exactly up your alley?

What Matters Most

3y↑1

Honest and a good review Ruzeen! I would add that with a single focal eyepiece you will not only get a bit sharper image but batter contrast as well, but for $60 US it's just 1 eyepiece to carry around . Over SvBony don't make the highest quality products but usually for the money and for a newbe or a semi user a very good products at lower cost.

AstroFarsography

Thank you Christopher. Yes that's what I think is a beneficial and gold thing about SVBony. They make (what I reckon) is decent gear at a good price point for the beginner fleshing out their initial toolkit

Hi Ruz great video and nice to see you working on the SvBony product; underexposed in the UK & US reviews. This looks to be a nice product, but I think it lacks the T-adapter option, I would find that useful for FOV control on my DSLR I primarily use with my Altair Starwave 80ED. I have the SvBony 305, and their helical focuser on my SCT (SE 6) these are good products too.

AstroFarsography

Thanks Tony. Yeah it's nice using SVBony stuff cus I think they position themselves in a decent market area and are somewhat underexposed. I remember when I first encountered them I couldn't find any reviews or content on them

The Urban Astronomer

Great review Ruz! Looks like a nice zoom eyepiece, not parfocal I guess based on what you said about refocusing after changing zoom. Just a quick question - does it have threads for attaching to a t-adaptor under the rubber sheath at the viewing end? The comparable celestron zoom does and it is a really useful feature to have.

AstroFarsography

3y↑1

Thanks mate. It is nice yes but not parfocal. As for the eyecup I didn't notice in my time but I also wasn't in the business of peeling bits back. I'll have a look at sometime tomorrow if I remember and get back to you

Leon Corns

I keep a celestron zoom eyepiece on my refractor. it's great for the moon. I think svbony make affordable and yet decent products so I would buy that eyepiece if I didn't have one.
It's nice to have a selection of prime eyepieces but for a beginner or for occasional astronomy a zoom eyepiece is ideal as long as you don't mind refocusing a little.

AstroFarsography

3y↑1

Agreed about the affordable and decent products. This is the second SVBony piece I've had to use and I've been quietly impressed with them. Ideal for the beginner or occasional, considering how expensive some eyepieces from the big boy brands can get

Christophe Kon

Man, Thank you for letting us feel your passion so clearly. I didn't even need a translator to understand you, it's so interesting and objective. Please stay the way you are

I don't do a lot of visual, but as you say it is nice sometimes just to do that, or let the kids see things. I have the Baader Hyperion Zoom IV 8-24mm, with it, I can unscrew the rubber eyepiece and attach a camera as well, which allows for taking images of the same object and different zoom. It also has 1.25" and 2" noses. Almost 4x the price of the SVBony though!

AstroFarsography

Yeah absolutely. For kids as well yeah I can fully see the appeal and usefulness of a zoom

Marcos J Pinto

3y↑1

For me this will be a great option - will buy one. Thanks for the review.

Charles Badstones

I got to try a zoom eyepiece last night and it was amazing. If i use say a dedicated 8mm eyepiece it may be difficult to find an object because of the zoom and perhaps not in focus yet. With the zoom eyepiece you can start at wide 24mm, locate the object, then zoom on in to have it centered at 8mm rather than struggling to find it.

NebuloCity

Great vid, Ruzeen! I have the Baader Hyperion Mark IV 8-24mm along with the Baader Planetarium 2.25x Barlow, and 2-inch Coma Corrector. All three are great pieces of equipment and really maximize the optics for visual astronomy, especially for kids or times you don’t want to swap in various eyepieces in one evening.

Sir Malus

@Dragos Marinescu Buy Baader buy once. 🙂

Dragos Marinescu

BAADER !? They cost an ARM& a LEG......

How the different zooms is really awesome! I have 4mm and an 28mm eyepiece , visual here and there is always awesome!

AstroFarsography

3y↑1

Yeah the different zoom is super handy especially at that range. My main prime eyepieces were 20, 10 and 4mm so with this one eyepiece I've got 2/3 of my normal lengths. Super handy

Night Stargazer

3y↑1

Thankyou for sharing your review on the zoom eyepiece. I have been interested in them. I have the svbony 9mm eyepiece and am very happy with that brand, so crisp and clear high quality. The details on the moon were awesome!

Sergio De Luis

Telescopio

dcobbism

Glad that you admitted that they gave you this, its very obvious in your review. I don't own this and I would not get it simply because of the extremely narrow FOV of 38-56. Also your 80ED using this at 20mm (which is roughly ~42FOV) you would most certainly cutoff the edges of Andromeda, clearly not the picture you posted in the video, so I call BS on that one. I've read this has decent optics for it's price point, but I consider it way too constricting on the FOV

Also how do you not know what an eye relief extension is?

Greg

3y↑1

Always one wanker in the comments section……..great review and thank you

AstroFarsography

I'm not really a visual user so I wasn't 100% sure whether the sliding eyecup was for eye relief extension, I thought it was but confirmed it before I committed to it.

As for the field of view, that's what I remembered seeing. I don't always write the review the same day as using it so I was going from memory to a degree, and using the figures posted and that I could find in the specs of this eyepiece.

Yes I've heard zoom optics usually have narrower fields of view compared to their prime counter parts which was a downside I was made aware of after the review unfortunately.

Also I aim to be as transparent as possible. So if something is loaned or given, then I'm owning up to it and letting everyone know about it from the get go :)

Abhiroop Bhattasali

If you want to picture planets with your phone zoom eyepieces are a blessing. Spot the planet at 21 mm then zoom to 7mm and 2x zoom with phone. With a Dobsonian setup that's all you need to picture planets.
Best thing is you can just take out your smartphone adaptor and view the planets yourself. It never gets boring.

AstroTom UK

Nice one mate, good review. Just like you I'm more digital. But do like to use visual from time to time. Not a bad price either to be honest. 👍

AstroFarsography

3y↑1

Thanks Tom. Yeah agreed really well priced for the range it covers for us "every now and again" viewers.

David Brandenburg

3y↑1

svbony makes some nice eyepieces at a very good price, I love my 25mm plossl from svbony!. paid like 15 dollars for and its better than my orion. if you need a good 15mm, the orion expanse can't be beat for the view!.

AstroFarsography

That's really cheap for an eyepiece! I actually think SVBony hurts themselves with their price points cus if I saw $15 for a 25mm EP I would think it was a plastic kelner or something and I'd avoid it 🤔

Allen Mitchell

3y↑3

I'm an astrophotographer for myself, who keeps a few eyepieces laying around for the nights I'm volunteering at the local school for their astronomy club, or the neighborhood kiddos that want to look at the moon from time to time.

AstroFarsography

3y↑1

Yeah eyepieces for them purposes really are handy to have laying around!

omer faruk

3y↑1

All hail AstroFarsography! I recently decided to buy this eyepiece but like everytime searched for a review of the product. Unfortunately I wasn't able to find any proper review of this product so I didn't bought the product. Thank you a lot for great timed review and this video. Have clear skies!

AstroFarsography

Thank you Omer that's too kind of you. I'm glad that my review was well timed for you. Has it validated your decision to buy then?

Astro La Vista

3y↑1

Thanks Ruz, that's pretty cheap for a zoom considering it covers a bunch of focal lengths. As you say well worth a look if you're an imager who wants to observe occasionally. It's a shame zooms tend to have a relatively narrow apparent field of view at the wide end although the flip side is they have a relatively wide AFOV at the short end which is handy, so good for high mag work with non tracking mounts. It's something like only 40 degrees at 24mm though which is a touch narrow for me being a bit of an eyepiece snob lol. For the price it's going to be good for travel setups too!

Astro La Vista

3y↑1

@AstroFarsography Yeah, I started off with visual then got into imaging, then when the kids where born I needed to find a quicker and more convenient form of astronomy so got back into visual in the form of eyepiece testing. For a few years I get really into buying, testing, then selling eyepieces on the second hand market.

AstroFarsography

3y↑1

Thanks Chris. So I guess this wouldn't fit in your eyepiece case then as a self confessed "snob"? 😉 You do enjoy visual don't you?

ghost70

3y↑1

Looks just like the baader zoom eye piece with same eye relieft. Does that come off to reveal a thread for attaching t-rings and cameras? I only use my baader for outreach with kids or for star alignment and keep my main set for me :)

AstroFarsography

I've heard a few people saying it's similar to the Baader version. As for the eyecup I never checked as I didn't think to check. I'll look at some point tomorrow and get back to you if I remember to check!

dunno yolo

2y↑2

Would you say the Celestron zoom would be a better option and better quality ?

Nik Ax

3y↑1

I'm trying to remember the last time I used an eyepiece. Hard from our light polluted skies but if I take the potable gear way then for sure.

AstroFarsography

3y↑1

Yeah I'm in B6 skies and I do question the validity of visual. I know I could have it worse though. I really do think about getting s large dob or something for them nights

Joshua Tuason

Is it possible to fit this on top of a monocular without replacing the eyepiece? I'd like to have this zoom functionality on my monocular

kevin Kennedy

2y↑1

Hey man how good is the eye piece after a year ?

AstroFarsography

Hey Kevin. Used it the other day and a couple months ago and still right as rain, still useful and as a visual dabbler it's still a great thing to have to hand

Vinfaz

3y↑1

can you do a review on the sv205 or sv305, there isn't much coverage on them but I want to know if they are worth it because they have some promising specs (the sv205 claims to have a 8MP sensor).

AstroFarsography

I've been asked if I'd like to review them cameras actually. We'll see what happens and what comes in the post, I'm yet to receive a reply from SVBony though

Phil Golden

3y↑1

Nice! How about a comparison of a Baader, Seben and Celestron Zoom eyepiece's. All have a M42 thread for a T-Adaptor for prime focus. The Baader being the most expensive but is that worth the extra price??

Phil Golden

@AstroFarsography Would it be worth reaching out to the companies and requesting them for a review? 6.08k subscribers; if even 2% buy any of the eyepieces because of it that it would be worth it to them (122 people).

AstroFarsography

If I had all the eyepieces to hand I'd love to do a shoot out review between them. But I don't and won't have the money to be able to do that sort of test :(

MARS 22

Can you attach this to a t ring for eyepiece projection
I mean does it have the threads under the eye cup?

FΛDΣ

What about for terrestrial views? How well does it perform there?

jlight sin sin

thank you very much ,,I was debating but now I'm going to purchase one right now..

Trummerkind

The drawback with this eyepiece is that one has to adjust the focuser everytime magnification is changed...and that makes it quite a pain in the ass

A B

3y↑1

But wouldn't one have to do that anyway when swapping eyepieces?

Don R

Thanks, Ruz! Nice review.

AstroFarsography

Thanks Don! 😁

Jules E

TY for the review :) I just bought it's sister (10-30mm) to try it !

Wade Austin

Have you received this yet. I’m thinking about getting one. Do you like it?

AstroFarsography

You're welcome. 10-30 is a nice range as well, enjoy!

Chris B

I own the svbony 7-21 is there any point in owning this one too?

Peter D Morrison

The best eyepiece is the one you use the most.

Richie Bricker

Whats a descent yet affordable ($20 to$50) 10 mm eyepiece for a beginer

Oat Cam

Would this be too heavy for a skywatcher ST80 frac on a basic AZ mount?

Oat Cam

@Douglas Casagrande thanks. I bought it and love it. Its a superb item 👍

Douglas Casagrande

I don't think so, I have the Orion ST80 EQ1. But I have the 7-21mm zoom. It's a lot lighter than the 8-24mm and it has a wider true field of view.

Astro_Pach

Is it compatible for celestron space explorer lt 127az??

--

Useless puff piece, zero views through the lens.

Shameful.

Naeromusic

Nice stellaris music ;)

AHMAD ALBAB

Nice...

Tekno Ultra

l buy it 10 30 mm it's just 33 degrees look this is really bad l really not recommend you really need single eyepieces and when you make zoom something it's move inside lens but very shaky not stability really no need and l buy 32 mm 52 degrees lens bey very good for look moon

iain anderson

not a single telescope image...... totally useless and worthless review

pls1745

2y↑1

@AstroFarsography I agree the camera doesn't show what the eye shows so a verbal review is much better. I will definitely be buying one as I carry enough stuff around when viewing visually. A few quick view zoom in and out sounds good. And it's damn cheap as well.

AstroFarsography

I considered it. The best I could have probably done is a mobile phone image through the eyepiece and when I considered the image quality, it seemed like it wouldn't have added anything to the review - so I opted to leave it out. That is assuming you wanted to see astronomical images and not photos of birds or trees.

If I review any other eyepieces in the future I'll reconsider my options on how to take a photo through the eyepiece.
