SVBONY SV503 Telescope, 70ED F6 Extra Low Dispersion Refractor OTA, Micro-Reduction Rap Focuser, for Astrophotography

I wanted to purchase a travel telescope and was looking for a very good telescope since my main telescope is an Orion ED80 with FPL 53 glass. I love my Orion ED80 and didn’t want to lug it around and cause any damage to it. Enter SVBONY ED80 with FPL51 glass. My jaw dropped when I viewed the moon with a SVBONY 7-21 zoom eyepiece. There was ZERO difference between this scope and my Orion ED 80 with FPL 53 glass. I am not kidding. It amazes me to see how SVBONY can deliver such an amazing scope at this price point. I will go one step further and state that the focuser on the SVBONY is much smoother and easier to reach focus. As and added bonus, it came with the mounting rings too. This telescope amazes me and I highly recommend it to anyone who is looking for a workhorse of a telescope with excellent image quality. Don’t let anyone tell you otherwise. Get them while they are still available. I ordered a High quality Binoviewer and just can’t wait for it to arrive to pair it with this telescope for planetary and brighter DSO viewing. Clear Skies.

Super petite lunette pour l’astrophoto quand combinée avec le sv193 de la 80ED pour corriger le champ. (Le champ n’est corrigé que jusqu’à des capteurs de 16mm de diagonale). Petites aberrations chromatiques présentes sur les étoiles brillantes mais facilement corrigé avec un filtre sv231 qui les fait totalement disparaître. La lunette est bien construite, entièrement en métal avec dualfocuser super précis. Très bon choix bon marché comme en attestent quelques photos que je partage en + prises avec cette lunette avec des temps d’intégration de moins de 1h.

Muy buena calidad, me gustó mucho.

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.
