What a pleasant voice and great review! Subscribed! 👍

This video has just given me peace of mind to go ahead with the purchase! Looking forward to trying mine out when it arrives, being my first widefield refractor I'm looking forward to shooting M31. Great video as always and thank you!

Really good SV503 70ED review video, thanks, sir.🥰

As ever, great information explained very simply. I was already going down this road (I think), but you've now persuaded me. Thank you for what you do!

I have the SV503/80mm ED version with the field flattener. The R&P focuser is buttery smooth and a joy to use and the scope has absolutely minimal chromatic aberration given that it's a doublet design. It's superb. Everything about these scopes is beautifully constructed. The field flattener while quite an expensive addition is very well worth buying is astrophotography is your thing. There is also a 102mm ED scope in the range. SvBONY also make some of the best Plossl eyepieces I've bought. This is my forever portable refractor scope.

Excellent review. Many thanks!

It's a very nice little scope. Small short focus refractors are very versatile and produce very acceptable images, and when used visually, they can deliver stunning wide field views when paired with an eyepiece capable of handling their fast f-ratios. What you describe as an inconvenience isn't really an issue ( for me ). I never liked the vixen rail, so I purchased a 7 inch ADM dovetail plate and the shoe to fit a Stellarvue unit power red dot finder, and you're good. That's my setup for a W.O. Megrez 72fd, which is similar to your set up. Thanks for the review. Clear Skies.

good info. man thanks

Nice video, do you own the flatener/reducer for that scope?...if so, have the link?..I'd really appreciate it, thanks. CS!

Nice review bro! Im very excited to try this scope on SA Gti , will get it later , i have buy this scope today , and SA Gti will get maybe around this mid August

Thanks! Amazon has these on sale for Prime Day for just $340. I just ordered one. I should have it Monday.

Nice video 👏👏👏👏👏👏 question what app did you use to download the images. That’s freaking awesome 🔥🔥🔥🔥

Thank you for the video. I’ve been looking at the Svbony scopes but had a hard time finding a solid reviewer. I own the Start Tracker 2i so this would be a great scope for a small build.

I bought one of these yesterday with the flattener/reducer. It should arrive tomorrow. I hope it images better than my Gskyer short tube 80mm achromat.

Bought this with the reducer, it's awesome! Nice and crisp for the horsehead I'm working on.

Thanks!

Is your camrra modified? I have a canon t7 modified by astrogear. Wondering if it will help with this scope or if ill definitely need a flattener.

Could you recommend some tripod for that kind of telescope? It will be for a beginner use. thx in advance

Is there much difference between this and the Skywatcher 72Ed?

I bought the 80mm f/7 of this scope. It is really nice! clear views, almost no aberrations, may update to field flattener but photos look great. The only suggestion is to place the finder bracket on the main tube, not the rotatable section because it does twist over time.

Have you had any issues with focusing? On min, I have to turn the focusing knob all the way in to a point the tube actually falls off the guide rack. I am using a Svbony field flattenener / reducer. I can never get this to focus clearly. Thx Mike

Can i use my existing m42 to canon adapter to attach to the field flattener to do i need a m48 to canon t ring?

Were the sample images taken with out a filter or with a filter. It looks to be unfiltered/broadband filter as the stars look very natural. Thanks.

I just ordered the model. Would a two inch optolong filter fit in the back of the focuser?

Not sure why my comment disapeared so will ask again. What field flattener do you recommed for this scope? There are two svbonys available. Thanks

What kind of mount to track sky objects to longer time exposure can I look into on a budget that would work with this refractor?

Not clear if it's APO or achro?? Why the SVbony company don't show it clearly in the spec?

pls correct me, its light enough to work on the star adventurer right?

I thought it weighed 3 kg. You recommend using it with a sky watcher star adventurer whose load capacity is 5 kg to this added that I use a canon 90D. Greetings from Chile.👌

How is the Orion nebula red from a sub? My center is green for subs and I have to process to get rid of that color

Thanks for the great review. It helps me make a purchase decision. But please let me point out a common error that many You Tubers make in talking about ED glass. Dispersion is a bad thing. ED glass helps to prevent dispersion. I believe ED glass actually means extra low dispersion glass. Not extra dispersion (dispersion is bad). I am no expert, and I will apologize if I am wrong. But on this matter I am quite confident.

How does this scope preform in visual astronomy?

I’m torn from buying the 80 or 70,,any advice

Great review but I've got a question can this scope be attached to Nikon d500 and can it mounted on any tripod?

Electrical tape on the dovetail plate 😉 If you know, you know

Based on this review and some others, I bought this little scope along with it's dedicated field flattener / reducer for astrophotography. Unfortunately the experience I had with this scope fell quite short of the praise given here on this channel. First, the flattener / reducer failed to flatten all stars except for the very center. Within a 4/3 crop field of view, there is sever elongation starting about half way towards the edges of the frame becoming almost comet like at the edges. Secondly, I expected some chromatic aberration since this scope is only a doublet with ED glass, but what this scope delivers are pretty much all purple stars. It may be suited for observational astronomy, but for astrophotography this scope is basically unusable in my opinion.

Did I see that right, you got good stars in an DSLR with no field flattener edge to edge?

how about SV550?

I can't make up my mind. I've done a lot of research, and i got my eye in the SV503 80ed & the WO Zenithstar Z61. WO slightly more $, but much lighter. 🤔

Were any filters used?

Hello, I'm considering this scope for astrophoto, but also for occasional visual / observation, I will like your opinion to buy, just one or maybe two but no more than that, an eyepiece that covers the most spectrum to planets, some nebula, and the moon for this particular scope. Thanks!!

ED = Extra Low Dispersion glass.

for sure that tripod is way beyond ' department store' quality. they are essentially junk. good tripod actually more important than the telescope, to me.

like can someone actually just review this scope
