V predydushem otvete vse sovershenno verno, no net otveta na pervyi vopros 
RA 4.35941 oznachaet pryamoe voshozhdenie v dolyah chasa, to est' 
4h 30m stanet 4.50000, sootvetstvenno 4.35941 = 04h 21m 33.88s 
Dec 12.11749 - sklonenie v dolyah gradusa, to est' 
12.11749 = 12 ° 07' 03.0" 
 
Ostaetsya vopros ob epohe koordinat. Naskol'ko mne izvestno, koordinaty na 
epohu nablyudeniya dayutsya kraine redko, obychno po umolchaniyu privodyatsya koordinaty 
J2000 
 
P.S. Seichas sushestvuet neskol'ko rasprostranennyh form predstavleniya 
koordinat, vklyuchayushih epohu, naprimer: J121342.4+100521, chto oznachaet  
R.A.=12h 13m 42.4s  Dec.=+10 ° 05' 21" na epohu J2000, ili 
B010503.5-000250, oznachayushee R.A.=01h 05m 03.5s  Dec.=-00 ° 02' 50"
