Ir Digital Ccd Video Camera
Scientific and aesthetic astronomicalimaging split only recently. Images of galaxies, star clusters andnebulae, published in popular astronomy books only a few tens of yearsago, were mostly captured for research purposes. When a state-of-the-arttechnology like CCD cameras, wide-field optics, precision telescopemounts and powerful computers become accessible to amateurs, the verybest images of deep sky wonders start to be captured by amateurs forpure joy and satisfaction from beautiful universe. Still, sometimes theyillustrate some interesting and important astronomical phenomena, likethe birth on new stars on the Rosette Nebula image acquired by ThomasLelu.Updated: 6.9.2019. Very fast download speed is definitely one of the highlightfeatures of CMOS sensors. Despite the 1.5 MPx camera C1-1500 offered up to 60 FPS upon its introduction, the sensor itself offerseven faster digitization.
Newly released firmware for all C1 cameraseffectively doubles the digitization frequency of the used sensors andthe C1-1500 camera now provides images at 120 FPS. Firmware update is fully automatic, literallysingle-click action thank to newly introduced CxFirmware updatetool.Updated: 14.8.2019. Gx Mark II cameras are available in many variants — individual G2, G3 and G4 series offer camera integrationwith internal or external filter wheels, Off-Axis Guider adapters,various threaded adapters as well as standard Canon EOS and Nikon lensbayonet adapters etc. One of the distinguishing feature of Mark IIcameras is the telescope/lens adapter interface allowing preciseadjustment of optical axis (sensor tilt). Despite the vast variabilityand many options, the Gx Mark II camera system was designed to maintainadapter-specified back focal distance of adjustable adapters on allcamera variants.Updated: 26.9.2018. G4 Mark II cameras inherited all proven design concepts andfeatures from the previous generation, like precise electronicsproviding uniform frames and extremely low read noise, efficientregulated CCD cooling, reliable mechanical shutter, modular mechanicalconstruction ensuring compatibility with wide variety of accessoriesincluding off-axis guider adapters, external filter wheels, Ethernetadapters, guiding cameras etc.
But Mark II cameras bring some importantenhancements, like much faster download speeds and adjustable (tiltable)telescope adapters.Updated. The cooled G2 series Mark II CCDcameras were developed for imaging under extremely low-light conditionsin astronomy, microscopy and similar areas. Design of this seriesinherits from earlier G2 Mark I cameras butbrings some significant enhancements.
G2 cameras employ preciseelectronics providing uniform frames and extremely low read noiselimited only by CCD detector itself. Modular mechanical constructionallows various camera variants to be combined with rich set ofaccessories, including telescope adapters, off-axis guider adapters,internal or external filter wheels, Ethernet adapters, guiding camerasetc.Updated: 11.6.2018. Standardized software interfaces bring the possibility to usevarious devices in many programs, providing device manufactures as wellas software developers implement particular standard. ASCOM standard forCCD cameras and other astronomy equipment is widely used within theWindows operating system, while a new INDILIB initiative stars to appearas emerging standard in the world of Linux-based operating systems.Libraries and drivers supporting this standard are now available for allCCD cameras of the Gx series, connected through both USB andEthernet.Updated: 8.12.2016. 64 bits is a newmarketing buzz-word in the world of mobile phones and tablets, but it israther common in the world of Personal Computers.
Despite the64 bit systems are available for manyyears, especially recently number of newly installed 32 bit systems sharply declines and 64 bit systems dominate. Surprisingly, generalunderstanding what does it mean is very low and particularly baffling isthe fact, that 64 bit operating system is(fortunately) perfectly capable to run 32 bit applications.

The answer to the question whichdriver version (32 bit or 64 bit) to install requires understanding of a fewconcepts.Updated: 19.5.2017. The ability to capture individual exposures through variousfilters is one of the key features of the cooled CCD cameras, regardlessif being used for scientific research or for astronomical photography.This is why the Gx CCD cameras were designed to include the filter wheelinside the camera head and to integrate filter wheel control into cameracontrol from the beginning. When more than 5 or 6 filters are necessaryor the filter wheel has to be used with G4 camera, the filter wheel istoo large to be placed inside the camera head.
