Max Image depth with ASI 174?
Unlike all the recent discussion of the benefits of stacking AVI files, I need to be able to work with the individual frames within the AVI (or SER).
I'm imaging the solar spectrum at nominated wavelengths - Ha etc.
The ASI 174 single image shows me, in 8 bit Mono setting (FireCapture/ SharpCap) that the image saturates at 256 ADU and the best absorption feature sits around 70ADU. This was at 0.55ms exposure and 70fps.
I'm working through various settings but increasing the exposure will start to impact on the frame rate - I also need the maximum frame rate possible.
(FC seems to default to SER files when set to 16bit - but no obvious improvement)
Any comment/ insight/ advice more than welcomed.....
