SharpStar 140PH f/6.5 Triplet APO

The triplet objective in the SharpStar 140PH uses two ED (Extra-low Dispersion) glass elements instead of the more common single element. This provides a higher degree of color correction, virtually eliminating chromatic aberration (false color fringing) for sharper stars, higher contrast, and more accurate color rendition in astrophotos.

While not a lightweight "grab-and-go" scope, the 140PH is designed to be transportable. Its net weight is 10.1kg and it has a retracted length of 738.6mm, allowing it to fit in most vehicles. It requires a stable equatorial mount capable of handling the 11.7kg gross weight with accessories.

The SharpStar 140PH excels at high-resolution planetary viewing and imaging. Its 140mm aperture and apochromatic optics deliver high-contrast, color-pure images, allowing you to resolve fine details like the cloud bands of Jupiter and the Cassini Division in Saturn's rings, approaching its theoretical 0.83 arc-second resolution limit.

For stable astrophotography, you will need a robust equatorial mount with a payload capacity of at least 15-20kg (33-44 lbs). This ensures the mount can comfortably handle the 11.7kg gross weight of the telescope plus any additional cameras, guide scopes, and other accessories without compromising tracking accuracy.

Absolutely. While designed as an astrograph, its premium optics provide stunning visual views. With a limiting magnitude of 11.5, it can reveal faint deep-sky objects, and its high-contrast, color-free performance makes it an excellent instrument for observing the Moon, planets, and bright double stars.

The Andromeda Galaxy is a large target. At the native f/6.5 focal ratio, you get a detailed view of its core. By adding the optional 0.73x reducer, you change the focal ratio to a much faster f/4.8. This provides two benefits: it widens the field of view to better frame the entire galaxy and its spiral arms, and it reduces required exposure times by more than 40%.
