CMOS sensor 11664 x 8750 pixels, USB 3.0 interface
C5 camera series is designed to accommodate the latest generation of extremely large Sony IMX CMOS sensors with 100 and 150 MPx resolution and diagonal dimension up to 67 mm. Many of the used sensor properties share the exceptional features of the sensors used in the C3 series, including the 3.76 μm pixel size with the full-well capacity exceeding 50 ke-, very high quantum efficiency thanks to back-illuminated design and very low dark current. C5 sensors also offer 16 bit digitization, perfectly linear response to light and exceptionally low read noise.

C5 cameras look reveal the same time-proven design school of the C3 and C4 series in both outer shape and also internal construction. C5 camera head front cross-section is the same like the in the case of C3 and C4 series, although the used sensors are much larger. C5 head thickness corresponds to the thickness of the Enhanced Cooling versions of the earlier models. But still, C5 series feature completely redesigned air cooling — more powerful and also quieter than even the EC variants of the C3 and C4. Also, the supplied AC/DC brick power adapter is more powerful and employs more robust power plug.
Usage of large sensors required completely new design of the telescope interface and the C5 series offers M68 × 1 threaded adapter only on the smaller 100 MPx C5 variant. Large 150 MPx version of the C5 standardizes on the M85 × 1 thread on the tiltable adapter. Like in the case of the C4 series, the internal filter wheel is not an option, external filter wheels are necessary and the C5 camera are equipped to control new EFW-5XL series of filter wheels. Huge sensors require huge 65 × 65 mm square filters and EFW-5XL-5 is designed for five such filters. The EFW-5XL-7 filter wheels for seven smaller 50 × 50 mm square filters are available for 100 MPx C5 variant with smaller sensor.
Rich software and driver support allow usage of C5 camera without necessity to invest into any 3rd party software package thanks to included free SIPS software package. However, ASCOM (for Windows) and INDI (for Linux) drivers and Linux driver libraries are shipped with the camera, provide the way to integrate C5 camera with broad variety of camera control programs.
