Hi, I've considered upgrading my Canon R7 to a used R5. I mainly shoot wildlife, but the option to shoot Astro/Aurora is important as well - and not having a crop sensor could be very handy there.. Even though the R7 is ~2 years newer, the R5 should still outperform the R7 on both scenarioes, right?
Is the upgrade worth considering? Or should I potentially wait for black friday offers? (Even though I don't imagine the price of a new R5 to get near the price of a used one)

What, specifically, do you want to do that you cannot do with your R7?

Photographing astro and aurora images generally uses a very wide angle, fast lens. Such lenses gain a benefit from using a full-frame sensor. For wildlife, with a FF camera, you will lose some of the telephoto 'boost' effect gained from using a crop sensor. However, the R5, at 45MP is sufficient for most people shooting wildlife, as I do myself.
To see an explanation of the relationship between crop sensor cameras and full-frame ones, and the implications of that, read the following Word document shared from my MS OneDrive:
Equivalence: How sensor size impacts Field of View, Aperture and shutter speed
The questions that should be considered are what kinds of wildlife do you shoot and, most significantly, what kinds of output do you produce.
There are other issues with regards to the performance of the R7 as a wildlife camera body that may, or may not impact you. Those issues are not true of any of the full-frame variants. See this video on the subject:

Essentially, the pixel density of the R7 is too high for the focusing system, the sensor (resulting in electronic shutter lag), and the data bus. Lower pixel densities of the full-frame bodies do not have these issues and they have much better focusing systems.
