since the 694 has a smaller surface area than the 8300, it would look bigger in the 694 with the same 10inchF4, is this correct

the noise mainly shows up as graininess in the background

it is cropped to roughly 1/4 of the image I think. To put in perspective, the attached image is a full sub, scaled down by 0.5 to fit - it shows how big M104 is re the full field.

M104 will be bigger in the 694 image because the 694 has smaller pixels. The difference in scale will be about 1.2 linear or about 1.4 in area.
