Top Refractor Telescopes for Deep-Sky Astrophotography and Planetary Viewing
Assessing and Listing Top-Rated Telescopes from Over 70 Refractor Models
In the world of astronomy, refractor telescopes are a popular choice for both visual observing and astrophotography. Here, we highlight some of the best high-quality refractor telescopes that push the limits of their mounts and are suitable for planetary and lunar viewing, as well as deep-sky astrophotography.
Celestron Omni XLT 102 and 120 Refractors
The Celestron Omni XLT 102 and 120 Refractors are 4-inch and 5-inch apochromatic refractors with focal ratios around f/6.5. Known for their decent aperture and high optical quality, these telescopes are suitable for both visual observing of the Moon and planets, and beginner to intermediate astrophotography. They come with mounts designed to support GoTo tracking, which is important for long exposure imaging but may be near their practical limits with heavier imaging payloads.
Celestron Advanced VX Series 6" Refractor GoTo
The Celestron Advanced VX Series 6" Refractor GoTo combines a 6-inch refractor optical tube assembly (OTA) with an Advanced VX equatorial mount. The larger aperture improves light-gathering for deep-sky objects while the Advanced VX mount is a solid mid-range motorized mount capable of supporting astrophotography setups that push beyond entry-level optics and mounts. This system offers a versatile balance allowing both wide-field deep-sky imaging and high-resolution lunar/planetary views.
Other Notable Refractors for Deep-Sky Astrophotography
William Optics RedCat 51
A compact, apochromatic Petzval refractor (51mm aperture, f/4.9), the William Optics RedCat 51 is optimized for wide-field deep-sky imaging with superb color correction and sharpness. It is lightweight and pairs well with lightweight mounts, though its small aperture limits planetary/high-mag imaging and deep faint object detail without longer exposures.
Askar V 60mm and 80mm APO Refractors
Highly innovative modular triplet refractors (f/6 to f/6.25) with exchangeable lenses and included reducers/flatteners, the Askar V 60mm and 80mm APO Refractors excel in color correction and clarity, offering flexibility for both visual and imaging purposes. Their sturdy dovetail and rotational features make them compatible with a variety of mounts and suitable for amateurs advancing in astrophotography.
In summary, for pushing mount limits and achieving both deep-sky and planetary imaging, the Celestron’s Advanced VX 6" refractor system stands out as a top option balancing optical quality and mount strength. The Omni XLT 102 and 120 are good all-rounders for those starting to push their mounts but with slightly smaller apertures. For specialized wide-field imaging with portability, the William Optics RedCat 51 is exceptional but less suited for planetary. The Askar V line provides modular, high-quality optics well-suited to progressing astrophotographers who want flexibility.
