## Customer Reviews

### ⭐⭐⭐⭐⭐ A "Must Have" accessory if you have the SVBONY SV503 70ED or the 80ED Refractor
*by P***H on May 19, 2025*

This is a "must have" for the SVBONY SV503 80ED and the 70ED. On the 70ED telescope, it drops the focal ratio from f/6 to f/4.8 for a wider field of view and slightly brighter (faster) image. With the 70ED, I was able to get the entire Pleiades cluster on my ZWO ASI183MC Pro camera sensor with almost zero vignetting.

### ⭐⭐⭐⭐⭐ Not Five Stars by Far..
*by P***T on December 3, 2022*

Not happy at all. You can definitely see the stars in all four corners look like eggs. When you look at a non cropped picture like my Christmas Tree star cluster and Cone Nebula shot you can see what I’m talking about. I do not recommend. I also had a sv503 that I purchased that the whole focuser just came loose during a session. I walked out to check on my rig and noticed that the camera was completely sideways. You could literally wobble the focuser back and forth. I purchased the ATO and reducer back in September and only got to use it a handful of times. I’d recommend maybe saving a couple bucks and purchase something of more reliable quality. When I contacted customer support. All they did was send me a couple of screenshots and an explanation of what a retaining thumbscrew was used for and after a couple of emails svbony dropped the ball on me. Not happy but lessons learned trying to save a couple of bucks.

### ⭐⭐⭐⭐⭐ Excelente, pero...
*by D***Z on June 2, 2024*

Me llego manchado. Nada que no se solucionara con una mi kit de limpieza de lentes, pero igual es algo raro para algo nuevo. Asumo error en el control de calidad del producto. De ahi en fuera funciona perfecto.
