Nu otlichno, ya rad za razrabotchikov INASAN. A kak Vy dumaete, pochemu SShA ne osilili v horoshem kachestve (bol'shIm zerkalom) imenno ul'trafioletovyi diapazon (na kakom-to drugom sputnike, naprimer). Ved' u nih bol'she resursov vsyakogo roda (deneg naprimer), a samyi interesnyi diapazon (kotoryi nel'zya poluchit' ni s zemli, ni s vozdushnogo shara) oni kak-to propustili. Neuzheli oni dal'she vozdushnogo shara 240-sm zerkalo i ne zapuskali?

>""Nepoladka", tochnee, prisutstvie korrektiruyushego fil'tra, proyavlyaetsya v umen'shenii effektivnoi ploshadi, a ne uhudshenii uglovogo razresheniya".
Vy tol'ko chto skazali vazhnuyu vesh'. Davaite predstavim, chto u nas est' zerkalo teleskopa 240 sm. A teper' v zerkalo (vot nezadacha) popal meteorit, i otkololis' kraya zerkala (ono stalo ne 240 sm, a skazhem 40 sm diametrom). Chto u zerkala pri etom umen'shilos'? U zerkala pri etom umen'shilas' effektivnaya ploshad' (ploshad' kazhdogo kusochka deistvitel'no men'she, chem vsego zerkala). Pri etom sohranilos' (ostalos' prezhnim) uglovoe razreshenie (t.k. krivizna zerkala ne izmenilas').
To est', "nepoladka" poluchaetsya takogo roda, chto na orbite my imeem ekvivalent malen'kogo zerkala.
A ved' malen'koe zerkalo gorazdo proshe zapustit' na orbitu, chem bol'shoe, ne pravda li? A ostal'nye diapazony fotkat' s vozdushnogo shara (ili samoleta) bol'shim zerkalom...
Interesno, kakie mogut byt' dokazatel'stva, chto Habbl eto Habbl, a ne kombinaciya iz "malen'kogo" sputnika i "bol'shogo" vozdushnogo shara (ili samoleta)? Po hronometrazhu mozhet byt' chto-nibud'?
