NGC6188 nebula
 We already published an image of NGC6188 nebula complex on our title page, taken by a famous group of astro-photographers named CielAustral. But this was only a partial image of this large cloud of interstellar matter. Now the same group presents almost 48 megapixels image mosaic, covering much wider portion of the sky and allowing us to admire incredible details in the gaseous structures. (more...)
SIPS version 3.22
 Majority of new features of the Scientific Image Processing System version 3.22 are related to the word “Scientific” in its name, improving astrometric and photometric processing of images taken for research purposes. Also, the single important bug-fix of this SIPS release concerns unreliable astrometry plate solution of arbitrary rotated images. (more...)
C4 Series 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. (more...)
SIPS version 3.21
 The major new feature of SIPS (Scientific Image Processing System) version 3.21 is support for C4-16000 scientific CMOS cameras and also significantly enhanced functionality of existing Cx cameras. SIPS is continuously evolved, new functions are added and the capabilities of the program grows. However, continuous evolution of software sometimes damages some existing feature and unfortunately SIPS is not immune to this problem, despite we try to test every released version thoroughly. This happened to SIPS version 3.20.2, when one new function under development, not yet present in released version, caused problems in guiding. This problem is now fixed with new version 3.21. (more...)
C1+7000 and C2-7000 cooled CMOS cameras replace the G2-1600 CCD camera in research applications
 New cooled CMOS cameras C1+7000 and C2-7000 offer quite large pixels of 4.5 μm, especially compared to majority of other CMOS based cameras available. As CCD sensors, often employing much bigger pixels, are no longer available, even relatively small increase in pixel size of a CMOS sensor significantly increases some key parameters like dynamic range (pixel area and thus also a number of electrons each pixel can accommodate corresponds to the square of pixel dimension). (more...)
Galaxies NGC4725 and NGC4747
 NGC4725 and NGC4747 galaxies in the constellation Coma Berenices are angularly smaller and also dimmer compared to big and bright spirals like M31 or M81. Therefore, these galaxies are much less often imaged and generally less known. Still, high quality image shows them in their full beauty and details. (more...)
Comet C/2020 F8 (SWAN)
 Comet C/2019 Y4 (Atlas) disappointed northern-hemisphere observers by breaking into pieces and thus it will not reach the brightness everybody hoped. But another comet C/2020 F8 (SWAN), visible from the southern hemisphere, evolves into beauty and brightness. (more...)
C1+ Series CMOS Cameras
 C1+ camera models 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. (more...)
M82 “Cigar” Galaxy
 The M82 is also known as “The Cigar Galaxy”. It can be seen close to more famous spiral M81 “Bode” galaxy in the constellation Ursa Major. While the bigger and brighter M81 shows nice spiral structure, somewhat chaotic appearance of the smaller M82 caused the galaxy was considered to be irregular. Only recent observations in infra-red light revealed also M82 has spiral arms, only not that prominent, because we see the galaxy almost edge-on. (more...)
C2 Series 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. (more...)
C1 Series CMOS Cameras
 The C1 series cameras with global shutter CMOS sensors 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. (more...)
New firmware for C1 CMOS cameras doubles FPS
 Very fast download speed is definitely one of the highlight features of CMOS sensors. Despite the 1.5 MPx camera C1-1500 offered up to 60 FPS upon its introduction, the sensor itself offers even faster digitization. Newly released firmware for all C1 cameras effectively doubles the digitization frequency of the used sensors and the C1-1500 camera now provides images at 120 FPS. Firmware update is fully automatic, literally single-click action thank to newly introduced “CxFirmware” update tool. (more...)
SIPS version 3.14 released
 SIPS undergoes continued development and new features are regularly added with every minor version release. This release brought the full support for the new Cx CMOS-based astronomical cameras, but numerous other features and enhancements were also added — for instance SIPS now understands two new types of star catalogs. (more...)
Back Focal Distance of Gx Mark II cameras
 Gx Mark II cameras are available in many variants — individual G2, G3 and G4 series offer camera integration with internal or external filter wheels, Off-Axis Guider adapters, various threaded adapters as well as standard Canon EOS and Nikon lens bayonet adapters etc. One of the distinguishing feature of Mark II cameras is the telescope/lens adapter interface allowing precise adjustment of optical axis (sensor tilt). Despite the vast variability and many options, the Gx Mark II camera system was designed to maintain adapter-specified back focal distance of adjustable adapters on all camera variants. (more...)
CCD over-scan region configuration tool
 CCD sensors are manufactured with total number of pixels somewhat greater than useful number of pixels comprising image. By default, camera returns only image pixels. But some users may appreciate full image, including shielded pixels outside of the image area (called over-scan regions). Over-scan regions may be useful for some specialized image processing etc. despite they are always cropped from final image. (more...)
The Gx CCD camera drivers for INDILIB
 Standardized software interfaces bring the possibility to use various devices in many programs, providing device manufactures as well as software developers implement particular standard. ASCOM standard for CCD cameras and other astronomy equipment is widely used within the Windows operating system, while a new INDILIB initiative stars to appear as emerging standard in the world of Linux-based operating systems. Libraries and drivers supporting this standard are now available for all CCD cameras of the Gx series, connected through both USB and Ethernet. (more...)
Gx Camera Ethernet Adapter — Standard, Mini and Micro versions
 Gx Camera Ethernet Adapter allows connection of Gx series cameras (models G0 to G4) to the control computer using Ethernet interface and TCP/IP protocol stack (this means over Local or Wide Area Networks). Single Gx Camera Ethernet Adapter contains four USB 2.0 ports and allows connection of up to four Gx cameras at the same time (regardless of the specific series, cameras can be freely combined). (more...)
What can 64 bit operating system do and which driver versions to choose?
 “64 bits” is a new marketing buzz-word in the world of mobile phones and tablets, but it is rather common in the world of Personal Computers. Despite the 64 bit systems are available for many years, especially recently number of newly installed 32 bit systems sharply declines and 64 bit systems dominate. Surprisingly, general understanding what does it mean is very low and particularly baffling is the fact, that 64 bit operating system is (fortunately) perfectly capable to run 32 bit applications. The answer to the question which driver version (32 bit or 64 bit) to install requires understanding of a few concepts. (more...)
External filter wheels for Gx CCD cameras
 The ability to capture individual exposures through various filters is one of the key features of the cooled CCD cameras, regardless if being used for scientific research or for astronomical photography. This is why the Gx CCD cameras were designed to include the filter wheel inside the camera head and to integrate filter wheel control into camera control from the beginning. When more than 5 or 6 filters are necessary or the filter wheel has to be used with G4 camera, the filter wheel is too large to be placed inside the camera head. External filter wheel is then the only option. (more...)
