Hi bllche and welcome.
If your budget is $4500.00 for astro gear i am sure you will get some good ideas from some members here. I am not up there with the good gear as i am fairly new to this hobby so i can`t help you with any avenues to take. Don`t jump onto the first scope you see until you have a good shop around. Plenty of help in here just for the asking. Good luck.
