Starfield Gear60Q — 60mm f/5 Petzval Quad APO Astrograph

The Starfield Gear60Q is a compact 60mm quadruplet f/5 Petzval APO engineered for wide-field astrophotography with a simplified imaging workflow. The Petzval optical layout is designed so you can focus and capture images without the typical “spacer guessing” required by many refractors. The system specifies a 41–61mm working distance from the M48x0.75 thread (depending on focuser position), and an illuminated and corrected field of 44mm—sized to illuminate a 36×24mm (full-frame) sensor.

Optical Design: Petzval Quad for Wide-Field Imaging

Quadruplet Petzval configuration with built-in correction

The Gear60Q is specified as a 4-element Petzval design consisting of a 2-element FPL-53 objective and a 2-element corrector. This approach is intended to deliver a corrected wide field and streamline the imaging setup by reducing reliance on external spacing trial-and-error.

Working distance and corrected image circle

The page specifies a 41–61mm working distance measured from the M48x0.75 thread (depending on focuser position), and an illuminated and corrected field of 44mm to cover a standard 36×24mm sensor.

Focuser, Rotation, Tilt, and Filters

2.5" rack-and-pinion focuser with ball-bearing supported drawtube

The Gear60Q uses a 2.5" rack-and-pinion focuser with a drawtube that is described as securely supported by ball bearings for smooth, stable operation and for carrying heavier cameras and accessories.

360° camera angle adjuster (rotator)

A camera angle adjuster / rotator provides 360° rotation to frame targets without reconfiguring the telescope.

Integrated tilt adjustment for camera matching

The focuser assembly includes a tilter mechanism intended to help match the optical system to the camera for optimal performance.

Precision focusing and motor-focus support

A 1:10 gear reduction is specified for fine focusing, and the system lists support for connecting a motor focuser.

Integrated 2" filter holder (in front of the camera)

For imaging convenience, the Gear60Q includes an integrated 2" filter holder positioned in front of the camera.

Mechanical Package and Transport

Handle + long dovetail plate

The package includes an integrated handle for accessories and a long dovetail plate for stable mounting and balance.

Multicoated optics and a case built for imaging setups

Multicoated optics are standard. The Gear60Q ships with a soft case with die-cut foam, designed to accommodate an optional focusing motor (including Pegasus Astro or ZWO focusing motors) and includes a dedicated spot for your imaging camera.

Optional focusing motor disengages for manual focus

The optional focusing motor is described as easily disengaged, allowing manual focusing with a simple twist.

Gear60Q FAQ

Is the Gear60Q “spacing-free” for imaging?

The Petzval design is presented specifically to reduce the need for external spacing trial-and-error. The page specifies a working distance of 41–61mm from the M48 thread, depending on focuser position.

Will it cover a full-frame sensor?

The page states a 44mm corrected/illuminated field and indicates it will illuminate a 36×24mm sensor.

Does it include rotation and tilt adjustment?

Yes—features listed include a 360° rotator and a tilter mechanism for matching the telescope to the camera.
