Size: 70mm
I purchased the SVBONY SV503 70ED refractor telescope last summer, but due to weather (two hurricanes!) I was unable to try it out until late November. It performed beautifully! The first few targets were the Pleiades, Andromeda, and the North American Nebula. All came out fantastic. The FPL51 glass in the objective lens approaches the performance of APO scopes that are over twice the price. The dual-speed focuser is super smooth and it's easy to get perfect focus with a Bahtanov mask. The draw tube length of 90mm offers a wide range of distances for achieving focus with various spacers, filters, or the reducer. It also has markings (down to the millimeter) on the side of the draw tube to help get the focus back after making changes to the optical chain. If you have recorded the distance mark from a previous setup, going back to that setup is much easier to get the focus close, so that the time needed when doing that kind of a change is greatly reduced. The extendable dew shield keeps out dew and stray light and stays in place without getting stuck. Overall, the quality of the build is excellent. I also purchased the 0.8x reducer for this scope's bigger brother, the SV503 80ED and it works great with this 70mm f/6 to reduce it down to an f/4.8 focal ratio for a slightly wider field of view. I recommend the reducer with this scope. It is essential if you wish to capture all of M-31 (Andromeda) or M-45 (The Pleiades) in a single frame. As far as optical quality, images are sharp and bright. Even though it's not an APO, I didn't notice any significant blue or purple halo's around bright stars. They weren't completely eliminated, but the very minor ones that did show up were hardly visible or were easily removed via processing. I highly recommend this telescope for astrophotography.

This is a very nice scope, especially for its price point. I've taken some lovely images using this scope. From the start, I've used the focal reducer and found I could never get round stars to the corners; it doesn't give a very flat image. This scope is undoubtedly a good buy and perfect for getting into "serious" astrophotography. **Pros:** - Well built - Allows for very nice images with some post-processing. - The dew shield is retractable, which makes it easier to move around. - It looks really nice! - Sold at an excellent price, especially considering its good quality. - The tube rings are moveable and have a built-in handle. - Many more cool features! Love this unit. **Cons:** - I couldn't get round stars to the corners, but post-processing can overcome this. This is a really nice scope. You can get high-quality images at a relatively budget price. I liked it enough I bought the 70ED as well. I would not hesitate to recommend this scope. Like almost anything in astrophotography, you'll want to upgrade to a more flat field scope at some point.

Purchased this scope because I figured with the Ohara FPL51 ED optics it should be half way decent but was really surprised with it performance vs price ratio. I owned way too many scopes in the past 30 years but wanted a decent ED refractor with a good built quality and a focuser that would not slip with a big load on the back of it. This scope delivers and the built quality is excellent, it reminds me of the Willian Yang scope I have owned in the past. Focuser is excellent, smooth and precise plus no slippage like some crayford focuser I have owned. The rings are sturdy and I cannot knock anything about this scope. Now for how it works under the stars cause that is were the rubber meets the road and it sure does. Star test is like a two element 102mm objective with an ED element, it has a little bit of color on one side of focus and none on the other side but you can detect concentric diffraction rings that are a perfect circle but at focus there is NO CA, NO FALSE COLOR at all even when looking at the brighter planets and the moon. I have had this scope out on a good steady night and when seeing allows it does stupid higher powers like 275X but I have no other eyepiece/barlow combo that will go higher but the image is still sharp just get slightly dimmer but it takes power well. At F7 its just fast enough to get some really nice views of the brighter DSO's plus does a great job at splitting doubles but it works great on planetary and lunar. Years ago a scope with this type of performance would cost way over a Kilowbuck so this is an excellent value. I also like the fact if there was something wrong with the scope they would either refund your payment or replace the scope, many retailers would leave you out to dry if there were optical issues. Yes I am pleased and I would like to see them come out with a larger ED scope in the future.
