No sh~~ sherlock and the only ones right now who can only see brown dwarfs are NASA. So you saying you work for NASA by saying 'we'? It si called WISE by the way.

alright show me proof at your knowledge about other WISE telescopes because I think you are talking out your ass.

hello kettle and hello pot!
you still haven't answered my question and I can go all day today on this. I do have a day off.
Where can I purchase an infrared telescope for backyard use?
You can't. Most infrared light from celestial sources is absorbed by the Earth's atmosphere. Only a narrow window of near-infrared radiation (at wavelengths less than about 4 microns) reaches the Earth. Observations at these wavelengths requires that the infrared camera be cooled to hundreds of degrees below zero using a cryogen (such as liquid helium) and requires special solid-state infrared detectors (costing tens of thousands of dollars). Hence, it is impractical to consider a true infrared telescope for personal use.

As in the case of extrasolar planets, brown dwarfs can also be found if they happen to be orbiting a star; the presence of the brown dwarf is indicated by wobbles that it causes in the motion of its companion star across the sky. The radial velocity method has been successful in identifying a large number of brown dwarfs in orbit around stars. Telescopes equipped with coronagraphs may be able to image the candidate brown dwarf at visible wavelengths, as was the case with Gliese 229B.
