>Dalee, Habbl byl unikalen svoim vysokim uglovym razresheniem. Ni odnim drugim teleskopom takogo ne povtorit' (v poslednie gody adaptivnaya optika pozvolyaet sdelat' chto-to podobnoe, no na uzkom pole zreniya). Samoletnym uzh tochno.
Est' samoletnyi teleskop SOFIA s zerkalom 2.5 metrov. Zerkalo Habbla - 2.4 metra.
Vy schitaete chto u samoletnogo 2,5-metrovogo zerkala zametno huzhe uglovoe razreshenie?
A ved' na samolet vodruzit' takoe bol'shoe zerkalo navernoe gorazdo proshe chem na sputnik (inache by vmesto Sofii zapustili eshe odin Habbl). I obsluzhivat' ego legche.
>Krome togo, u Habbla svoya, sovershenno osobennaya, PSF (point spread function), kotoraya sil'no otlichaetsya ot drugih teleskopov. Svoi shum detektorov. Svoi razmer pikselei. Svoi vklad ot kosmicheskih luchei. I tak dalee. Chtoby poddelat' nablyudeniya Habbla, nuzhno ih proizvesti na teleskope luchshe Habbla, a zatem uhudshit' parametry tak, chtoby "mimikrirovat'". A takoe poka nevozmozhno :)
Eto vse ponyatno, no samoletnyi teleskop tozhe mozhet imet' svoi shum detektorov i razmer pikselei.
A tot parametr, na kotoryi ya hotel posmotret' (ul'trafioletovye luchi) - okazalsya uhudshennym (kak budto v kosmose nahoditsya malen'koe zerkalo, a horoshie (no ne ul'trafioletovye) snimki delayut vse eti gody samoletom a lya SOFIA)...
