This PHOTON Newtonian combines a 150 mm (6") aperture with a 750 mm focal length at f/5. Its parabolic primary mirror and fast optical geometry support deep-sky imaging and visual astronomy.
The manufacturer specifies 94% enhanced mirror reflectivity with a protective quartz layer. Secondary-mirror size and illuminated-field figures are specific to this aperture; the table distinguishes fully illuminated field from partial illumination where TS publishes both.
The metal tube is fitted with a 2" Crayford focuser with adapter to 1.25" and compression ring. Use the published dimensions and assembled-weight configuration when selecting a mount; cameras and other added equipment contribute further load.
A suitable coma corrector is optional for wide-field imaging. Native focuser backfocus is available mechanical travel/spacing, not automatically the sensor-spacing requirement of a chosen corrector. Keep primary and secondary collimation aligned for the installed camera train.
