CCD or CMOS or what??

(I think it was earlier for Nikon and earlier still for canon). The reason I say mostly, is not because I don't think it is all, but rather as a potential defence against the pedant who insists - What about camera XYZ (obscure and low volume) that employs it.



In the words of XXX from Little Britain .... "Yeah, I know"

I don't.

Hasselblad is a very niche manufacturer. At 50k plus per camera, very few photographers will be lining up to use them.

2010 is a LONG time ago when it comes to technology. Especially fast moving tech like imaging.

lol @ video!

I'm happy to give the benefit of doubt to the newer models that I haven't had the opportunity to use. The 1D had far better colours and DR imho (than either of my current Canon CMOS based cameras). I'd be curious to try Sony CMOS based cameras too - many Canon users are leaving Canon for Sony because of IQ I believe. I personally don't believe that Canon is at the forefront of DSLRs anymore - both Nikon and Sony outperform them.

I'm not aware of any DSLR model in the past 5 years being CCD based.

CMOS has technical advantages, but if we're talking purely IQ, I still honestly think CCD tech is better in that respect.

I think for astro imaging, CMOS is a better tech - colour purity isn't really any issue, nor DR, at least to the same respect as it is with terrestrial imaging. With that said, imaging is a combination of the scope, mount AND camera.

Also for software and applications? No more "CCD Astronomy" but "AstroCam Astronomy"??????????

Perhaps, the best of both worlds. To be pedantic, 'CCD AstroCam' or 'CMOS AstroCam'. A CDAC or CMAC.

I wonder what the rest of world thinks. Perhaps a poll. We could reinvent the wheel and a call it 'a wheel...'

Hmmmm
A generic term to encompass "all" types of sensor(s) used was the goal....

I think its perfectly acceptable to hijack the CCD TLA to also encompass CMOS with a slight modification. The D is valid as they are obviously both devices. The initial C is also valid as they both store a Charge. Its only the middle C (Coupled) that is specific to CCDs and is a fairly vague reference to how the charge is transported to the readout circuit. CMOS on the other hand is actually a description of the substrate. Maybe calling them both "Charge Capture Devices" is not unreasonable.

Seems a round about way of describing a "Digital Device"??????

Maybe "Digital Astronomy"???
