Ati uitat sa citati asertiunea aceasta, de pe acelasi link,  http://www.iceinspace.com.au/forum/showthread.php?t=40620    :)

"Well.. Canon DSLR is NOT an astrocamera. It is only capable of producing acceptable results. "
sau asta
" Thanks for the link. I have to admit I presumed they would be pretty much the same QE as single shot CCD cameras such as the QHY cameras, but that appears to not be the case, with some QHY cameras having about twice the QE (if I remember right). "

Apropo, cred ca n-ar fi rau sa discutam la un moment dat despre familia de camere QHY , dar nu acum inca...mai e timp si pana atunci sunt multe de epuizat, aici. :)






Eu .... eu vreau sa zic primul.... :lol: 
Eficienta cuantica este "unitatea de masura" a sensibilitatii unui senzor. Orice senzor cu matrice bayer (color) are o eficienta de 4 ori mai mica decat un senzor Alb/Negru...
Am zis bine?  :lol:

Imi permit un citat de pe un forum: http://www.iceinspace.com.au/forum/showthread.php?t=40620
este despre senzorii canon insa prin extrapolare se poate aplica tuturor senzorilor color (cu matrice Bayer)
These are the first reasonably precise measurements done of Canon CMOS Quantum Efficiency that I've seen:

Whats it all mean? In a nutshell, the Canon CMOS sensors are 1/5 as sensitive as the best monochrome sensors. This difference is mostly due to the bayer colour filters which cover the pixels
