SV905C Telescope Guide Camera 1.23MP USB2.0 Type-C Interface, Standard 1.25 inches for Astronomy Guiding
Compact, highly sensitive 1.23-megapixel colour guiding camera featuring a 1/3” CMOS sensor (1280×960). With small 3.75 µm pixels, high peak QE (~80%), and low read noise, it reliably locks onto faint guide stars for tight, accurate tracking.
Key Features
- 1/3” CMOS sensor (1280×960), 1.23 MP resolution
- Small 3.75 µm pixels for precise centroiding
- High peak quantum efficiency (~80%) and low read noise for faint-star guiding
- USB 2.0 output for simple, lightweight connectivity
- ST4 guide port for direct mount corrections
- Compatible with PHD2, Maxim DL (MDL), N.I.N.A., TheSkyX and other guiding software
- Front CS interface + CS-to-C adapter ring for CS or C-mount lenses
- 1.25″ barrel diameter fits guide scopes and OAGs
- Integrated snap ring and scale marks aid repeatable focus and positioning
Connectivity & Compatibility
- Interfaces: USB 2.0 data, ST4 autoguider port
- Guiding Software: PHD2, MDL (Maxim DL), N.I.N.A., TheSkyX, and other ASCOM/INDI-capable platforms
- Optical: CS mount with included CS-to-C adapter; 1.25″ barrel for guide scopes and off-axis guiders
Design & Mounting
- Form factor: 1.25″ cylindrical body for universal fit
- Focusing: Snap ring and etched scale marks for quick return to focus
- Use cases: Ideal for short-to-long focal-length guide scopes and OAG guiding
