Thanks JA for your detailed feedback. The Nikkor 300mm f/4 AFS is a good option because I can combine it with wildlife photography, but I question the difference between the AF-S and the updated PF version, which is half the weight at about 750grams.
This
review by Mansurov does not show much distinction, however notes that the PF version is sharper in the centre which, when considering cropping (as I am using a full-frame) would probably be the better option because i'll have a sharper image. With any lens, the capabilities change when doing deep space objects, and it seems like the PF would be the better option, but that it unfortunately becomes the more expensive option. The cost is far higher with the optically better VR2.
I just find it questionable whether the 300mm is necessarily suitable for astro imaging, but may be better if I combine it with daytime photography, which likely will not happen all that often as I prefer night photography and landscape.
Something like AT60ED with a reducer can reach that 300mm range and is very cheap and lightweight, but again, leaning to the RedCat simply because people vouch for it and it can also be used for wildlife photography too. The synthetic fluoride glass helps with FF images that are nice and flat.
Happy to get into more details on this if you feel I am leaning in the wrong direction with my POV.
