The solar gravitational lens's focal is around 550 AU which is very far. Can we send a few telescopes that will stop midway (let's assume 150 AU) to collect the light and work as interferometry?

$\begingroup$ Interesting question! Different but somewhat related: What might the first deep space telescope using the Sun or Jupiter as a gravitational lens be like? $\endgroup$– uhohOct 11, 2021 at 11:11
