This PHOTON Newtonian combines a 200 mm (8") aperture with a 1000 mm focal length at f/5. Its parabolic primary mirror and fast optical geometry support deep-sky imaging and visual astronomy.
Optics and illumination
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.
Focusing and tube
The metal tube is fitted with a 2" Crayford focuser with 1/10 dual speed transmission. Use the published dimensions and assembled-weight configuration when selecting a mount; cameras and other added equipment contribute further load.
Imaging configuration
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.
Exact named TS manufacturer model and its published technical table checked. Unpublished dimensions, capacities and package items are not inferred.
