Exoplanet closeups?

You can use the sun as a gravitational lens: https://en.wikipedia.org/wiki/Solar_gravitational_lens

You need to be about 550 au out.

whoa... why aren't we doing that?
Even cooler is setting up transmitters and receivers at suitable spots on opposite sides of two stars.
Veeger is currently less that 200 AU, and it's dying. For us to build a craft that could stay alive long enough to make it to 550AU and still be functioning would take an incredible leap in technology. This plan also has a fatal flaw in that you can only ever hope to look at one thing. You can't just slew that craft to be able to line up the next target.
You mean V'ger
