Atk 460 vs 490
Posted: Fri Aug 31, 2018 11:44 am
Hello.
I am finally about to go ahead buying all the equipment.
I will get a Lisa spectrometer to be used with my Meade 12"LX200.
I have some doubts about the camera.
Initially i decided to buy the Atik 460EX with the Sony ICX694 chip, but then i have my doubts if i should get Atik 490EX, with the ICX814.
Both chips are equal in size, but the 694 has pixels of 4,54 in size while the 814 has 3,69.
QE for both seems to be pretty similar, a bit higher for the 694. And the rest of the parameters are very similar.
I guess that read out time will be lower for the 694.
Any advice on those?
Thank you.
