Hi Paul,
OK, two thoughts.
First. Try what you have, you may be surprised, but I doubt it.
At the expense of sounding snobbish, I have always believed that optics is money driven. Sure there will be a bargain out there, and if you are not tooooo fussy you can use lenses of lesser quality, but........
Astro imaging demands good gear, sorry. If I was gearing up in your case I would look only at the "L" series, and these are not cheap. Try to find a few older "Press" lenses, ones that newpaper pros have replaced, and as long as the glass is scratched they will give good results. My preferrence would be a good 85mm, and maybe a 200mm. This is partly the reason I was happy to stay with Nikon, as most any older Nikkor will give decent results with the D100.
Try one of your current zooms, and let us see whether you need to splurge.
