This PHOTON Newtonian combines a 154 mm (6") aperture with a 600 mm focal length at f/4. 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 carbon fibre tube is fitted with a 2" Monorail focuser with 1/10 dual speed, 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.
Carbon 154/600 model: main technical table gives 550 mm length and 4.8 kg with rings/finder; introductory text describes 530 mm / approximately 5 kg. Table used; not mixed with metal tube.
