Hello,
Handy little link to compare cameras below.
Sorry, I have no idea but from what I have been looking $ for $, maybe DSLR with the extra years of development, as mirrorless is still newish... But a full sensor camera at a decent pixel pitch for $1.2-$1.5k is unreal.
I have been looking at the Z5 for an intro camera. The Z5 is around $1500 depending on your kit, but I am after a full sensor camera for "newb with no idea" for around $1500 or less. From what I have read, serious people would go straight to the Z6, just 2k and under at body only.

Try astrophotography sites that allow you to choose the camera used, telescope aperture, f ratio's etc. Look at your top 6 objects taken with a similar scope and the D7000, then try the 2k upgrade camera option and see if its worth the price of entry.

Ps. The Nikon Z series also does a full spectrum camera UV-IR which looks awesome, no idea how much extra for the function. (the pictures of flowers at UV-Visible-IR are incredible, makes you realise why insects use both)
Pps. The Z5 compares well to the old nikon-d610 but with new generation benefits.
"The bigger the pixel pitch, the further apart they are and the bigger each pixel is. Bigger pixels tend to have better signal to noise ratio and greater dynamic range" - The Z5 has a 25% larger pixel pitch, the Z series is full sensor so 133% larger than the D7000 and 10 years newer. Ten years is an eon in computer/electronic terms...
The reason I base most of my cameras off the D610 was from a youtube video on $6000 v $600 worth of astro gear. Well worth a watch and considering they had tracking issues with the $600 it compares surprisingly well imo.
