Customer Reviews (4.8 / 5 · 5 reviews)

Joseph Y. ★★★★★

Finally got clear shots of the moon with the 448mm focal length—the detail is stunning. The whole setup feels solid but isn't too heavy at 4.72kg.

John W. ★★★★★

Took this out on a clear night and the WIFD focuser held steady even when I swapped filters; the 448mm focal length gave me sharp, crisp views of the moon's craters.

John A. ★★★★★

Setup was quick and the Petzval optics gave me sharp stars right out of the box. At 4.72kg it balances nicely on my mount, and the integrated WIFD focuser holds position perfectly even with a camera attached.
