Sky Rover 155 GPS 155mm f/8 Super ED Triplet APO PRO Refractor OTA

Description

The two outer rings support the tube in the standard configuration. The third ring slides along the tube and serves as a movable counterweight mount for balance adjustment. Different configurations heavy camera vs. visual accessories vs. binoviewer shift the center of gravity. The third ring lets you rebalance without separate counterweight bars or slide plates.

Why does this scope cost what it does?
A 155mm triplet apochromat with individually tested optics, a steel objective cell, a 3.7-inch focuser and matching CAA, dual dovetail plates, a three-ring mounting system, and an aluminum case is not a commodity product. The glass alone 155mm of Super ED triplet represents a significant optical investment. Add the GPS-series build quality, individual testing, and the engineering that goes into a scope designed for both serious imaging and demanding visual work, and the cost reflects the instrument. This is not the scope you buy because it’s affordable. It’s the scope you buy because nothing less will satisfy what you’re trying to do.

Recommended Accessories

• Sky Rover 1 Field Flattener for 155 GPS (SR155GPSFF): The essential imaging companion. Threads onto the CAA for flat, pinpoint stars across the sensor at the native 1240mm f/8. Sold separately.
• Sky Rover 0.8 Specialist Reducer for 155 GPS (SR155GPSRFF): Drops the system to 992mm f/6.4 for faster, wider deep-sky imaging. A second optical personality for mosaic panels and large nebulae. Sold separately.
• Sky Rover 2″ Diagonal (SR2D): A quality diagonal for visual observing. Essential for comfortable use of the 155 GPS at the eyepiece.
• Sky Rover XWA 9mm Eyepiece: 100 apparent field at 138 an immersive view for deep-sky objects and planetary observation. At 155mm aperture, this magnification shows extraordinary detail on most nights.
• Sky Rover XWA 5mm Eyepiece: 100 field at 248 the high-power planetary eyepiece for this scope. On nights of good seeing, the 155 GPS at 248 through a 100 eyepiece is an experience that belongs in a different hobby.
• Sky Rover XWA 20mm Eyepiece: 100 field at 62 a sweeping, wide-field view that takes full advantage of 155mm of light-gathering power. Star clusters, nebulae, and Milky Way fields become immersive experiences.

Final Thoughts

The 155 GPS is the telescope at the end of the upgrade path. Over six inches of triplet apochromatic aperture in a steel cell, individually tested, with a 3.7-inch focuser and matching CAA, dual dovetails, a three-ring mount, and an aluminum case. It accepts both a 1 flattener and a 0.8 reducer for two complete imaging configurations. The binoviewer-compatible extension tube opens up visual modes that most refractor owners never experience. And the views on the planets, the Moon, double stars, and the deep sky are in a class that reminds you why refractors have a mystique that no other telescope design has ever matched. This is not the scope for everyone. It’s the scope for the person who knows exactly what they want, has the mount to carry it, and is ready to see what six inches of clean, unobstructed, color-free triplet aperture actually delivers. They won’t be disappointed.
