Ya uzhe pisal vyshe. Ne vydavaite zhelaemoe za deistvitel'noe.
Kak sleduet iz, po-vidimomu, neizvestnoi vam teorii difrakcii, uglovoe razreshenie menyaetsya, poskol'ku izobrazhenie, proizvodimoe ideal'noi linzoi v fokal'noi ploskosti, yavlyaetsya Fur'e-preobrazovaniem vhodnogo otverstiya (v dannom sluchae, formy zerkala). Uglovoe razreshenie ne zavisit ot fokusnogo rasstoyaniya.
> Interesno, kakie mogut byt' dokazatel'stva, chto Habbl eto Habbl, a ne kombinaciya iz "malen'kogo" sputnika i "bol'shogo" vozdushnogo shara (ili samoleta)?
Ya uzhe pisal, poetomu vynuzhden povtorit'sya. Vysokoe uglovoe razreshenie; PSF v UF i vidimyh diapazonah; kolichestvo kosmicheskih luchei na matrice; shum, razmery, chuvstvitel'nost', vzaimnoe polozhenie detektorov; razmer pikselei, ...
Vy pisali, chto eto vam "vse ponyatno", no iz nashei diskussii u menya v etom postepenno zakradyvaetsya somnenie. Nadeyus', vy ponimaete, chto PSF - ochen' ser'eznyi argument.
