I think, that every large spectroscopic bucket telescope really ought to have a colocated wide field imaging telescope
like a 4m spotter telescope

"We find them smaller and fainter, in constantly increasing numbers, and we know that we are reaching into space, farther and farther, until, with the faintest nebulae that can be detected with the greatest telescopes, we arrive at the frontier of the known universe." -Edwin Hubble
The service tower attached to the iconic floating egg atop the Institute's Koffler accelerator (the "spaceship" in the photo, left) has recently been graced with a charming, shiny silver skullcap - an observatory dome.
I was doing a little research into the history of telescopes, and it was about a century ago that they finally realized how much more potential light-gathering power reflecting telescopes had as compared to the older
"I went into a clothing store, and the lady asked me what size I was. I said, 'Actual'. I'm not to scale." -Demitri Martin
Yes...that would be great! Now, to make it happen...
Well, that is kind of hard to do because of balance and the weight. I would suggest two, one on either side.
Are you thinking ground based or space-based?
yes, definitely!
You could probably be clever and just collect all the photons that weren't going down the slits -- essentially a 30m guiding camera. It would certainly be economical for dedicated long-slits. Masks would be trickier, but probably worth it in terms of differential cost vs building a second telescope.
