I don't think using a black hole as a gravitational lens would achieve your objective. A simple lens like a magnifying glass does not work like a set of lenses with well-placed relative distances like a telescope (or microscope). Try using a magnifying glass to see something in the distance. It doesn't work, it will only focus on something closer to it than it is to your eye.

This is all moot however because you would see those things with more clarity if you placed the space telescope close to them, to begin with.

Hmm I swear I read a thing or two about the concept! The idea being if you were at a certain distance away, the BH could capture and 'focus' light emitted behind it, such that the image would be in finer detail? Unless I misunderstood. And I briefly tried searching the web for answers, but could only find articles about basic concepts of lensing. I'll keep looking!

My thinking was, if this were indeed possible, you could maybe rotate around the BH to get many clearer images of many different objects
