I don't know that any Sony eats any stars since A7iii. What it mainly seems to do now is turn faint stars that are pinpoints, green.

They do, but the effect seems to be less noticeable.

I use an A7riii often for nightscapes. Its still very capable. But I prefer the EOS R Canon because despite a bit more noise which goes with stacking, the star colours are a lot better than with the Sony.

Color is about profiles, unless you are looking for Hydrogen Alpha response (near-infrared). In this regard the new A7 cameras are better than previous models.

The main issue with A7riv is the extra noise but handled by taking several shots and stacking them same as with any camera.

About 1/3 more than the A7rII, which is excellent, should hardly be noticeable when comparing final work.

Post some photos so we see this post is genuine.

Sure. Without samples we can't help that much.

The star colour issue with the Sony's isn't about profiles its a direct result of the star eater that suppresses blue and red leaving excess green. You get a lot of green faint stars on an image with pinpoint stars.

So far the astro images I have seen (admittedly not many) from the A7riv are disappointing.

Did you know QHY are selling a mono cooled version of this sensor (61mp)?

Apparently it has low noise and no amp glow.

Its also an expensive camera, a lot more than an A7riv.
