sv503 prime focus- Connected to M48 Camera Ring photography, also known as direct focus photography, is a method of directly using the telescope to take pictures without adding any optical objects between the telescope and the camera.The main objects of prime focus photography are nebulae, clusters and galaxies.This can be achieved by matching the sv503 set with the M48 camera ring.
Superb price/performance ratio
I owned a 102/1000 mm F10 Bresser achromat for some time, now I purchased the Svbony 102mm ED FPL51 and its significaltly better with a lot less chromatic aberrations. I like this refractor a lot, especially because it's sold for an excellent price
this was the best rig I could afford
This is the exact telescope I use with an ASI2600MC. With a 0.8X FF/FR and a Pegasus Focus Cube, this was the best rig I could afford.
Best price with high quality
I have the 102 and the 70 and I love them! Glad at got them before the tariff war being in the states!
Worth a look as a first scope.
I have the the 80mm version of this scope. I think for the price it's very good. It's not as good as a triplet but the difference is not big, mainly slight halos on bright stars. It's well built and nice to use. I have the reducer for it as well. It's my go to scope and I really like it.
This sv503 did really surprise me
I purchased the 503 102ed during the Black Friday sale with competitive price. Thanks svbony. I can proceed my hobby.
Nice gear I've own
I got one sv503 telescope a few months ago. Pretty happy with it.
it is a great set of equipment for the money!
This is a great set of equipment for the money and is a good scope for someone just starting out in the hobby or on a tight budget. It's nice to see that decent equipment is now available at a reasonable price.
For me anyway it was money well spent.
i have the 503, 102 for a few years now and i really like it, i use it with my asi 585 and it produces images i am happy with for the price of the setup. it seems to be a good match for a smaller censor i think most people buying a cheaper beginner telescope like this are not going to have an expensive apc sized cooled camera anyway. the chromatic aberration is a pain but it can mostly be sorted out in pixnsight.
Excellent ED optisc & focuser
I have the 102 mm ED verson from Svbony. I have used it for visual observations and photography, it's very very nice for the planets and the Moon (with filter) clearly better than my Bresser 102/1000 mm achromat. It also has an excellent focuser.
Good quality without breaking the bank
I've been using this scope for almost 2 years. Primarily DSO astrophotography with some visual use. I have zero complaints.
