Help 071 or 294

So beside the sensor size what is the main difference between these two ?

I’ve read a few people having issues with calibrating the 294 images. Why should it be any different to any other calibration ?

It has also been mentioned that the 294 is better for live stacking but the 071 is better for long exposure, is that true ?

What camera is more sensitive? The 294s sensitivity graph shows relative response whereas the 071 shows this as a percentage.

The 294 doesn’t have a anti dew window heater but one can be added ? How effective is the window heater and is it required ??

thanks ken

Compared to 071, 294 has higher QE.

So 294 is more sensitive, suitable for live stack.

But it has more amp-glow, causing difficulty in calibrating.

Also it is true that 071 is suitable for long time exposure, because it has smaller amp-glow.

294 does not have heated window, and it cannot add one, there is no need to add one.
