Ken,
Your way short with your budget, as someone else suggested you need 2 double it then add a zero on the end and then allow it in $US, $US 2,000,000 should keep me going
Powered site Dark Sky property with properly equipped observatory with appropriate electronics, kitchenette and sleeping quarters $US 200k
40" OGS Ritchey Chretien Main Scope $US 780k
8" Takahashi Flourite APO $US 170k
Cameras, Eyepieces and other
much needed accessories like
adaptive optics $US 200k
TOTAL COST $US 1,350k
And it looks like I have change out of my $2 mill to book a shuttle flight
Seriously for $AUS 100k I would set up a small dome observatory on a leased dark site housing a 16"/F5 equatorailly mounted newtonian with a 4" APO as a guidescope and have some change left over.
