Premier Stellarvue Optics! These are not mass-produced optics. The SVSX130 objective is hand figured in our optical shop in Auburn California to the highest optical specifications. We provide a certified test report demonstrating its optical prowess.
Stellarvue's six element, apochromatic, imaging astrograph is made with ED and Lanthanum glasses to create a wide, flat, excellently color-corrected field. The system operates at 655 mm focal length, f-5. Think of it as a Petzval using triplets on either end so no other flattener/reducer is needed. Each element is extremely broadband fully multi-coated to eliminate reflections. Combining these coatings with excellent optical correction, this imager is capable of reaching deep and showing more than smaller instruments intended for this purpose.
To further increase the ability of the system, we are using the Optec 3" TCF-S3 motorized, temperature compensating focuser. This focuser has 1" of travel, is extremely robust and stable. Once the temperature compensation is worked out, imaging is much less of a hassle as temperatures drop. The unit compensates for optical shift in this system as temperatures change. Everything is included, the Focus Lynx, Motor, Temperature Sensor and new hand controller. Since we include everything you can use this focuser both with your laptop or with the hand control.

Heavy duty CNC machined rings are made in our shop to mount the system rigidly and we include our TP13 Losmandy style plate with each system. Also included is our thickly padded C130L heavy duty case.
This astrograph is designed specifically for astro imaging at f-5. This is not a visual telescope. If you are looking for a 130 mm telescope that may be converted to an imaging astrograph our SVX130 is the telescope you need.
