Camera GPCAM2 IMX 290 a Colori Altair Astro ideale per riprese planetarie o autoguida è la sorella maggiore della GPCAM1, una versione migliorata e con un sensore decisamente migliore.

L' Altair GPCAM2 IMX 290 monta un sensore SONY Exmor IMX 290 CMOS, lo stesso della più famosa ASI 290 della casa ZWOptical, ma ad un prezzo decisamente più competitivo!

La camera può vantare un'altissima sensibilità e un bassissimo rumore, uno dei più bassi tra le camere che montano lo stesso sensore!

 Può essere utilizzata per imaging solare, planetario, lunare e anche per immagini deepsky o riprese video astronomiche.
TimeLapse a tutto campo (con l'opzionale obiettivo) è completamente supportata dal software.
Alcune delle caratteristiche molto interessanti del sensore IMX290, insieme al bassissimo rumore e alta sensibilità, sono l'altissima risposta della camera alla regione rossa dello spettro, rendendo la camera veramente sensibile e utile per riprese solari, inoltre possiede un alta sensibilità anche nelle regioni dell'infrarosso IR, che consente alla camera di essere usata anche in modalità mono. Utilizzando poi un filtro IR pass per riprese planetarie e lunari!
 
Pixel molto piccoli da 2.9x2.9 micron!
 
La porta USB 2.0 della GPCAM2 è decisamente più veloce della GPCAM1 (case blu), migliorando la velocità e la stabilità del trasferimento dati sul pc . Questo va ad eliminare completamente i file corrotti o persi, infine rimane utilizzabile su tutti i computer e notebook!
 
 
La camera possiede una porta autoguida ST4 e può essere usata come autoguida con le montature delle maggiori marche in commercio: iOptron, Skywatcher, Celestron, etc...

E' difficile se non impossibile trovare una camera con queste caratteristiche a questo prezzo!

The SONY Exmor IMX290 Color CMOS sensor has very low read noise, with 2.9 micron pixels and a large 1920x1080 array giving 2.07 megapixels. It is also BSI, or backside illuminated and carries the STARVIS rating.
 
Onboard buffering gives USB data transfer speeds significantly higher than the GPCAM1 series, pushing the USB2.0 format to the limit, yet within a stable envelope. This almost completely eliminates dropped frames, corrupted video, and enables faster more consistent frame rates, even with less powerful notebook computers.
 
The camera has an ST4 auto-guiding port, and can be used to auto-guide with mounts from all the major mount manufacturers supporting ST4 format, such as iOptron, Celestron and Skywatcher.
 
You would be hard-pressed to find a more versatile small-format colour astronomy imaging camera with this price and features.
 
And what's more, you get UK/EU based warranty support, plus the Altair Camera Google User Group for all your technical questions - a great place to share tips and techniques to get the best out of your camera.

The camera can be fully controlled in AltairCapture and SharpCap to output uncompressed .AVI and .SER video files for solar system imaging, as well as all common still image formats such as .JPEG .PNG .TIF .BMP, to mention just a few. The GPCAM supports 8bit or 12bit output. The 12 bit output mode can be used for deep sky imaging with less frames needing to be stacked and a wider pixel intensity range. The IMX290 sensor is extremely sensitive in the IR region (for all pixels not just red!) and can be used effectively with IR Pass filters for solar and lunar imaging in mono mode.
 
What’s different about the GPCAM2 platform compared to the GPCAM1 platform? You’ll notice the GPCAM2 casing is larger than the GPCAM. This is to house larger electronics boards which support trigger mode and frame buffering as well as to increase the surface area for cooling. The GPCAM2 platform supports “Trigger Mode” to make long exposures of over 5 seconds easier to control. With most cameras, in normal video mode, you have to wait for an exposure to complete before the camera will accept, say a command to abort the frame, for say clouds, aircraft, or an alignment issue, like kicking the tripod and so-on, or for routine changes in gain, exposure time, , re-aligning or refocusing on the object. For long exposures, normal video mode is inconvenient, especially for video astronomy and deep-sky imaging, however in Trigger mode, you can stop the camera instantly (even if you are half way through a long 30 second exposure) change the settings, and re-start the camera looping again. The GPCAM2 also has an improved onboard frame buffer to improve data transfer stability at high frame rates (to reduce dropped frames) and to increase compatibility with a wider range of PCs. The improved buffers give a more consistent data transfer rate over USB2.0 and USB3.0 buses on laptops and desktop PCs.
