The k10D is my first and only DSLR but, looking at the best of my past pictures, I'm not dissatisfied with it.
tho it's getting a bit long in the tooth now, ~ 9 years old ( the model) it's still a good general use camera

I'm summoning up the courage to get a more advanced Pentax. It has to be Pentax because I have a bag full of Pentax lenses.
yeah know that feeling ... I was in the same boat, I still have Pentax lenses left over from my film SLR cameras. But as I commented above, I really wanted to move to a full frame sensor camera and Pentax weren't keeping up with the times. I went out and spent a zillion bucks on a top camera and top lenses studio lights high end tripod ... yup, "the whole 9 yards" haha. And so pleased I did.
It wasn't till the beginning of this year that Pentax finally released the K1 full frame camera.

and it can make use of many of the older lenses ( mainly ones from around 1990 onwards)
The main advantage of the newer models ( ignoring the gimmicks) is lower noise levels with higher ISO settings and better resolution
as a result of better sensors and onboard processing ... great for astro work ( and imaging in general)
Other things, still not gimmicks, include faster focussing, better metering, more frames per second <--- sports photographers love that last one

And the sensor will have to be small so that I can use them.
all the Pentax dSLR's will take the APS-C mount Pentax lenses. The APS-C refers as much to the mount type as it does the sensor size.
From a sensor perspective, it is referring to a crop sensor, regardless of the brand of camera.

It seems that, if I want to be an Astrophotographer, I would be better off with a dedicated camera and they seem to be quite good value.
Presumably you are referring to a astro imaging camera ? as in ones like this ...

Seriously, don't worry about any of those for a while, if at all. So much awesome astro imaging can be done with just a camera, some different lenses and a
stable tripod for wide angle short exposure time milky way 30 sec or less exposures, through to longer exposures of deep space objects with a camera, zoom lenses and a tracking mount ... nay a telescope in sight
some food for thought
