SVBONY SV48P Achromatic Refractors

SVBONY SV48P refractors are achromatic doublet tubes sold as OTAs, ready to add to your own mount, diagonal and eyepieces. The 102mm f/6.5 has a 663mm focal length and the 90mm f/5.5 a 495mm focal length, both short enough for wide views of star clusters and the Milky Way.

As fast achromats, they show some color fringing on bright targets at high power, so they are most comfortable at low to medium magnification and for daytime viewing.
