SVBONY SV503 102ED - This one really did surprise me ! 

Interesting video. Svbony sells the 102 ED for 500 to 600 USD, all other companies sell this version for 750-850 $. It weighs just 4.0 kg and it is not a simple achromat, it's actually a semi-APO having FPL51 and Lanthanum glass. I own the Svbony 102/714 mm for 6 months now, previosely I had a Bresser 102/1000 mm F10 achromat and the Svbony 102 ED has a much better optical quality and performance. Also the 2 speed focuser is infinitely better than the ones used on simple achromats.

Great review Ollie it's always good to hear how people have got on with new equipment after a few months use not straight out the box would be interesting to see how it performs on the planet's and moon with sharpcap live stacking

Wow nice reviews with great captures and processing, will share it thanks so much 👍

I've been umming and aahing over this scope for a while. I can get the 102 ED for about £460, with the flattener/reducer, which is insanely cheap. For £100 more, you can get dew heater, carry handle, dovetail, bahtinov mask and guide scope, which is mad.

A side by side image comparison on the planets or DSO with the Svbony 102 ED vs the Skymax 127mm would be very interesting :)

Looks like a great scope for the price and it produced some nice images Ollie. Especially looks good for solar imaging as those solar images you showed had very nice detail.

Great review Ollie!. Clear Skies!!

Never EVER apologise for getting a new scope mate! 🤣 Awesome review and an achro works just great for Solar! I grabbed a 127mm Bresser for under 300 quid and it’s brilliant on the Sun…have fun Ollie! 🔭📸

I've been using this scope for almost 2 years. Primarily DSO astrophotography with some visual use. I have zero complaints.

I've been using one of these as my main imaging scope for a year now and it is very impressive for the price. I have it paired with a 294m and simple ZWO filters and it excels at NB imaging. With LRGB imaging you will see some blue halos but an Astronik L3 filter cuts them by half. I bought mine for less than $1000Cdn and it is worth every penny. For me it was a choice of this and a small SCT for galaxy hunting or a triplet. I haven't regreted my choice yet, having more flexibilty and the right tool has opened up more options than a single scope solution.

Hi, great video. I am looking into a 122mm svbony and i have 2 color ZWO cameras. And 122mm would sit on AM5 or AM3. Do you think the scope is good value? Sure seems so.

Those comments make a lot of sense - had not thought of this previously. Food for thought.

Time for me to dust off the Orion 120mm F5 Doublet. I have it in the corner of my room. Can't remember why I put it away.. time to get it mounted. Great video Ollie!

Nice review mate the scope you have is almost identical to the Altair astro 102 EDR I own only difference is mine has the FPL 53 glass, I think TS optics photoline is pretty much the same to so probable all made within the same supplier I'm guessing. I use the SVbony reducer with mine as it were far cheaper that the TS optics one & it works a treat.

Thanks for the verification of the theory that a good ED doublet is "good enough" for working with a monochrome camera and filters.

I see the tilter between the quark and the camera, what don't you like about that one and what would you use instead?

Did you happen to buy it off gumtree and how much did you get it for? I saw it listed a few months ago for 800 aussie with a metal case and field flattener 😂 I ended up buying directly from Svbony and it is my first proper scope for astrophotography.

just a question about the doublet, when putting the flattener reducer on it does that now make it a triplet 🤔

I have my ASI533 camera in it's level orientation so that the top of the image framing is pointing straight up. That results in my EFW to be pointing out to the side. For balancing purposes I would prefer the EFW to be pointing up like in this video. But that would change the rotation of my camera to an arbitrary orientation.
