----------------------------------- florincosta 05 Apr 2009 22:37 sfat achizitie nagler ----------------------------------- m-am decis sa cumpar un ocular bun,televue nagler.acum apare dilema 12mm,17mm,20mm,22mm stiind ca acestea sunt pe 2".telescopul meu e un dobson 300mm/1500.raportat la diametrul si focala telescopului care ar fi cel mai indicat? ----------------------------------- marius78 05 Apr 2009 22:44 ----------------------------------- Toate depinde ce vrei sa vezi cu ele. ----------------------------------- marius78 05 Apr 2009 22:46 ----------------------------------- La obsevatii planetare poti sa pui si de 4 mm ,te ajuta obiectivul ,ptr ca este destul de mare si imaginea este mai mult decat buna. ----------------------------------- Laurentiu 06 Apr 2009 01:34 ----------------------------------- Eu zic sa mergi pe cel de 20 mm (la focala de 1500 mm a telescopului ai avea astfel o putere de 75x si aproximativ 1 grad camp aparent). Pentru deep-sky, la un telescop de 30 cm diametru, ar fi super ok (bineinteles, ar fi si mai ok un ocular cu focala mai mare de 20 mm dar alea-s cam foarte scumpe cand vorbim de Nagler). @marius78: ocularele Nagler nu sunt "cu dedicatie" pentru observatii planetare. Pentru asta ar fi mai degraba recomandate ocularele Radian ( daca tot vorbim de oculare Tele Vue - dar trebuie sa ai buzunar doldora) ori (mai degraba) clasicele Orthoscopice. ----------------------------------- marius78 06 Apr 2009 07:54 ----------------------------------- Cea mai noua lista de pret de la Televue.
