Explore 68 SAW
The 68 SAW is a compact f/3.9 specialist astrograph built for wide-field astrophotography. Its 68 mm aperture and 265 mm focal length deliver a very fast imaging platform with a 44 mm image circle, making it suitable for APS-C and larger sensors in portable setups. The design emphasises mechanical rigidity and a built-in flat field for simple camera mounting.
68 mm f/3.9 specialist astrograph
44 mm image circle
Built-in flat field
Adjustable back focus
Compact, rigid CNC design
A focal ratio of f/3.9 increases photon collection compared with slower instruments at the same aperture, helping achieve higher signal-to-noise for a given exposure time. This makes the 68 SAW useful for wide-field targets and for imaging from portable field rigs where exposure efficiency matters.
The telescope includes an integrated flat-field optical layout delivering a 44 mm image circle, removing the need for a separate field flattener for many cameras. Performance is especially strong across APS-C and half-frame sensors, simplifying setup for full-frame-capable imaging without extra optics.
The OTA and focuser are precision CNC-machined as a single unit to reduce joins and improve rigidity. A 2.5-inch dual-speed rack-and-pinion focuser offers 29 mm of effective travel and is compatible with many motor focusers, supporting precise focus control in the field.
The default back focus is 55 mm and is slightly adjustable. The product description notes coordinated use with accessories such as off-axis guiders, filter wheels, and cooled cameras, but the design uses a shorter back working distance than conventional reducer systems, so follow the recommended adjustment and mounting procedures.
No. The 68 SAW is a dedicated astrograph and is not intended for use with visual accessories such as a diagonal.
Rear interfaces listed are M54 x 0.75, M48 x 0.75, M60 x 1, and M63 x 1.
The package includes the Sky Rover 68SAW OTA, tube rings, a dovetail plate, a carry handle, a finder base, and a soft carry bag.
