Leupold vx5hd 2-10 power, if you're willing to spend 6-700 bucks.
If not, then go 1 inch tube and get a meopta meopro.
This, at least the VX-5 HD part. I thought the wide-ish duplex wouldn't show up well in dim light. I was wrong. You'll have to pony up $100 over your budget cap though. Never tried the Meoptas, but I'm open to suggestion.
