CMOS and CCD cameras for astronomy, microscopy and other low-light applications.

Moravian Instruments Cx CMOS line and Gx CCD line of astronomical cameras are designed with maximum image quality on mind. Camera bodies are compact and robust, CNC manufactured from solid aluminum.

Small C1 and G0/G1 cameras are intended as autoguiders as well as Moon, Sun and planetary imagers. They are powered from USB line. Especially the CMOS sensor based C1 line offers very high FPS when connected through fast USB 3.0 interface.

Cooled CMOS C2/C3/C4 and CCD G2/G3/G4 cameras are powered from external 12 V DC power supply. These models are equipped with mechanical shutter and precise regulated cooling. All these models can be connected to external filter wheels, Off-Axis Guiders, various telescope and lens adapters and other accessories. C2/C3 and G2/G3 cameras can be also equipped with internal filter wheel, which makes them very compact, all-containing devices.

Cx cameras are equipped with 5 Gbps USB 3.0 interface, Gx series use 480 Mbps USB 2.0 interface. Up to four cameras of all types can be connected to the Moravian Camera Ethernet Adapter to access them through 1 Gbps Ethernet and TCP/IP protocol from virtually unlimited distance.

C4 CMOS cameras

The C4-16000 cooled scientific CMOS camera sensors offer the same geometry like the CCDs in the famous G4-16000 cameras — sensor size 37 × 37 mm, 9 μm pixels and 16 MPx (4k × 4k) resolution. Also the mechanical design of C4 cameras inherits from G4 Mark II cameras, which makes the C4 camera line fully compatible with vast range of telescope adapters, off-axis guider adapters, filter wheels, Camera Ethernet adapters, guiding cameras etc.

C3 CMOS cameras

C3 cameras employ the latest generation of Sony IMX CMOS sensors, offering exceptional quantum efficiency thanks to back-illuminated design and very low dark current. Despite relatively small pixels, full-well capacity exceeding 50 ke-. Combined with full 16 bit digitization and perfectly linear response to light make these cameras suitable for both aesthetic astro-photography as well as astronomical research. Sensor formats from APS to photographic full-frame (24 × 36 mm) ensure wide field of view and optimally utilize capabilities of the optical systems most commonly used by amateur astronomers.

C3 series CMOS cameras

C2 CMOS cameras

The cooled C2 series global shutter CMOS cameras were developed for imaging under extremely low-light conditions in astronomy, microscopy and similar areas. Mechanical design of this series inherits from earlier CCD-based G2 Mark II cameras, which makes the C2 series fully compatible with vast range of telescope adapters, off-axis guider adapters, internal or external filter wheels, Camera Ethernet adapters, guiding cameras etc.

C1× series CMOS cameras

C1+ CMOS cameras

The cooled C1+ series global shutter CMOS cameras are designed to fulfill the gap between small and lightweight C1 models, intended as Moon and planetary cameras and auto-guiders, and C2 cameras, equipped with active sensor cooling and mechanical shutter and thus intended for more serious astronomical imaging and research. C1+ cameras are able to work as C1 ones, only being somewhat heavier and bulkier, and at the same time C1+ can replace the C2 models, only with slightly less cooling performance and lack of mechanical shutter.

C1 CMOS cameras

The C1 series global shutter CMOS cameras were designed to be small, lightweight imagers for Moon and planets and for automatic telescope guiding. With proper image calibration, C1 cameras provide surprisingly good results also in entry-level deep-sky imaging. The used CMOS sensors response to light is linear up to very close to saturation point, so, C1 cameras can be used for scientific applications like variable star research, too.

External Filter Wheels for Cx and Gx CCD cameras

External Filter Wheels for G2, G3 and G4 CCD cameras offer more positions compared to internal filter wheels, embedded into camera head. External filter wheel is not connected to the host PC (with separate USB or serial cable) as well as to separate power supply. Only single short 8-wire cable connects the external filter wheel with the camera head. External and internal filter wheels are indistinguishable from the software point of view, same drivers are used to control them.

External filter wheels cannot be used together with internal ones. G2 and G3 cameras with internal filter wheel cannot be attached to external filter wheel — the camera is manufactured either with internal filter wheel or with connectors and thinner front case for attaching of the external filter wheel. Because of the filter size there is no internal filter wheel for G4 series of CCD cameras, these cameras can be used only with external filter wheels.

Moravian Camera Ethernet Adapter

Moravian Camera Ethernet Adapter allows connection of Cx and Gx series cameras to the control computer using Ethernet interface and TCP/IP protocol stack (this means over Local or Wide Area Networks). Single Moravian Camera Ethernet Adapter contains up to four USB 3.0 or USB 2.0 ports and allows connection of up to four Cx and Gx cameras at the same time (regardless of the specific series, cameras can be freely combined).

Model Supported cameras Ethernet interface USB 2.0 ports USB 3.0 ports Power supply Dimensions

Off-Axis Guider

Off-axis Guider (OAG) adapters are designed to allow attachment of any guiding camera with 1.25" eyepiece nose, although the nose must be somewhat shorter to achieve focus. G0 cameras are designed to achieve focus with Gx OAG and a special shorter version of 1.25" nose with C-mount thread is available for all G1 cameras. Any camera with CS-mount (short version of C-mount standard) can use this adapter to be attached to all variants of OAG adapters.

Off-axis guider adapters for G2 cameras are equipped with standard M42 × 0.75 (T-thread) or M48 × 0.75 thread on the telescope side in a proper 55 mm back focal distance. This means G2 camera with OAG can be used on numerous optical systems, including Newtonian coma-correctors, refractor field flatteners etc.

OAG-2-M48 G2 Internal, EFW-2S 55 mm M48 × 0.75 1.25 "

Off-axis guider adapters for G3 and G4 cameras are equipped with M68 × 1 thread on the telescope side in the distance 61.5 mm from the detector. Two variants (for G3 cameras and for G4 cameras) differ in the mounting holes placement and also in the distance of the reflecting mirror from the optical axis.

Camera control and image processing software SIPS

Powerful SIPS (Scientific Image Processing System) software, supplied with the camera, allows complete camera control (exposures, cooling, filter selection etc.). Also automatic sequences of images with different filters, different binning etc. are supported. With full ASCOM standard support, SIPS can be also used to control other observatory equipment. Specifically the telescope mounts, but also other devices (focusers, dome or roof controllers, GPS receivers etc.).

SIPS also supports automatic guiding, including image dithering. Both “autoguider” port hardware interface (6-wire cable) and mount “Pulse-Guide API” guiding methods are supported. For hi-quality mounts, capable to track without the necessity to guide at last during one exposure, inter-image guiding using the main camera only is available.

But SIPS is capable to do much more than just camera and observatory control. Many tools for image calibration, 16 and 32 bit FITS file handling, image set processing (e.g. median combine), image transformation, image export etc. are available.

SIPS handles FITS files, supports image calibration and processing

As the first “S” in the abbreviation SIPS means Scientific, the software supports astrometric image reduction as well as photometric processing of image series.

SIPS focuses to advanced astrometric and photometric image reduction, but also provides some very basic astro-photography processing

SIPS software package is freely available for download from this www site. All functions are thoroughly described in the SIPS User's Manual, installed with every copy of the software.

Drivers for other software packages

Drivers for ASCOM standard as well as native drivers for third-party software are also available (e.g. TheSkyX, MaxIm DL, AstroArt, etc.). Visit the download page of this web site for current list of available drivers, please.

Also INDI drivers for 32 bit and 64 bit Linux running on x86 and ARM are available. Also drivers for TheSkyX package running on macOS are supplied with the camera.
