🌌 Capture the cosmos in ultra-wide, crystal-clear brilliance — don’t let the stars wait!
The SVBONY SV193 is a premium 2-inch 0.8x focal reducer and field flattener designed for refractor telescopes like the SV503 80mm F7 ED. Featuring a 3-element, 2-group fully multi-coated lens system housed in a durable anodized aluminum body, it reduces focal length for a wider field of view and faster exposures while eliminating star distortion at the edges. Compatible with full-frame cameras and 2-inch filters, it’s an essential astrophotography accessory that enhances image quality and efficiency.

A "Must Have" accessory if you have the SVBONY SV503 70ED or the 80ED Refractor
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.

Excelente producto
Complemento para el telescopio Svbony SV503 80mm, monto el aplanador de campo y me ayudó a enfocar los objetos de corta distancía al menos de unos 2Km. Espero complementar la información en los comentarios del telescopio propio ya haciendo pruebas de observación de espacio profundo. Pero excelente compra.

Accesorio indispensable para realizar astrofotografía con un telescopio refractor semi-apo.
Reductor focal y aplanador de campo. Elimina la coma en la periferia del campo visual y además ofrece reducción de la longitud focal en un factor de 0.8, lo que permite hacer exposiciones un poco mas cortas.
