Explore 110 SAW
The Sky Rover 110 SAW is a purpose-built wide-field astrograph offering a fast f/4.8 focal ratio and a 45 mm image circle for full-frame sensors. Its integrated two-group optical layout and rigid mechanical design prioritise stability and imaging performance for dedicated astrophotography rigs.
110 mm f/4.8 specialist astrograph
45 mm full-frame image circle
Built-in flat field
3.2-inch dual-speed R&P focuser
Rigid integrated optical structure
The 110 SAW uses a front triplet group and a four-element rear group that are factory matched into a single, co-optimized optical system. That integrated layout aims to deliver the fast focal ratio and reduce vibration sensitivity compared with widely separated Petzval-style reducer arrangements.
Sky Rover specifies a built-in flat-field design with a 45 mm image circle, intended to support full-frame imaging with minimal vignetting at the sensor edges. This removes the need for a separate field flattener in typical full-frame setups.
The OTA includes a 3.2-inch dual-speed rack-and-pinion focuser with 38 mm of effective travel, plus an integrated CAA, finder base, tube rings and a multi-function handle. These mechanical features make it easier to build a reliable imaging rig and to focus precisely when imaging.
The telescope provides nominal back focus values of 55 mm at the M48 interface and 75 mm at the M54 interface, both described as slightly adjustable. Rear interfaces also include a 2-inch option, letting you match spacing to your camera and adapters within the stated limits.
With a 110 mm aperture, 528 mm focal length and a contracted length of 740 mm (840 mm extended dew shield), the OTA weighs 6.3 kg and ships with tube rings, a dovetail plate, handle and an aluminum carry case. That combination balances imaging capability with reasonable portability.
No. The 110 SAW is a dedicated astrograph and is not designed for use with visual accessories such as diagonals.
No. The front and rear optical groups are factory matched and should not be disassembled or separated. The front group contains residual aberrations and cannot function correctly on its own; separating them will severely degrade image quality.
Nominal back focus is 55 mm at the M48 interface and 75 mm at the M54 interface. Both are described as slightly adjustable for real-world optimisation. Rear interfaces listed are M54 x 0.75, M48 x 0.75 and 2-inch.
