Description
The Starfield 6" F/4 Imaging Newtonian Telescope is built for observers and imagers who want serious performance in a fast, quality-focused optical tube. Designed with deep-sky imaging in mind, this Starfield Newtonian F/4 Reflector Telescope combines strong contrast, reliable mechanics, and thoughtful details that make setup, collimation, and camera use straightforward.
Starfield Newtonian F/4 Reflector Telescope Key Features
Optical Performance You Can Trust
The primary mirror is made from BK7 optical glass for excellent thermal stability. It’s dielectrically coated for high reflectivity and protected by a durable SiO2 (quartz) layer. The mirror sits in a cell with six easy-to-use collimation knobs, and the center spot makes laser collimation simple—ideal for keeping an f/4 system dialed in. This Starfield Newtonian F/4 Reflector Telescope is built to hold alignment and deliver crisp, contrasty views.
Precision Focuser for Modern Cameras
A 2" rack-and-pinion focuser with 10:1 dual-speed control comes standard, offering smooth, repeatable focusing with the lifting power needed for a DSLR or CMOS deep-sky camera. It’s also EAF compatible for easy motorization, and you can add a motor for automated focusing.
Built-In Stray Light and Accessory Readiness
The matte-black tube interior reduces reflections, while the extended OTA length helps block stray light for better contrast. Split tube rings with felt protect the finish and include a Vixen-style dovetail with adjustment screws. M6 mounting points on the rings make it easy to add accessories or a top dovetail.
Included Accessories
An 8x50 finder scope and extension tube are included for visual use.
