Composite "All Spectrum" Telescopes ??

[Widdekind]

Planets are much dimmer than stars. Perhaps, then, you could do a "Hubble Deep Field" type, Long Duration image, of targeted star systems ? Blocking the light, from the central star, by standard means ("artificial eclipses"), such a "Planet-Finder Deep Field" might image many dim planets, perhaps as "arc-like" smears across the image, from the light accumulated over many days, weeks, or even months.

 

Moreover, imagine training an "phalanx" of telescopes, each observing a different EM spectrum, at the same star system. Then, you could create, in composite, an "all spectrum telescope", which would image the target star system in everything from Radio to X-Ray (say). Such would "drink down" as much light information, from said star system, as was available, as quickly as possible.

 

Between both of these suggestions, you could create "composite All-Spectrum, Deep Field" images, of the Planetary Systems, of targeted star systems. Could such "long duration, broad band-pass" images maybe make up for the intrinsic dimness of planets ?
