That the machine is equipped with a sensor cooling system and modified to expand the infrared emission, in practice remove an existing filter and replace it with one with these features then tell you better the owner

Mario2006,
le reflex non nascono x la fotografia astronomica. x questa ci sarebbero i ccd. Ormai da molti anni le differenza sono diventate poche (lo dico avendo 3 reflex e 2 ccd) ci sono pro e contro in entrambe. I ccd ancora forse più potenti (se si esclude la tendenza di mercato a fare cmos rafreddati ), le reflex più snelle come setup.
Vengo al dunque.
1) modificata
per renderla più sensibile a frequenze tipiche della luce emessa da corpi celesti come nebulose, galassie ecc. Viene tolto il filtro originale e montato uno specifico. Di giorno ti ritrovi con "le nuvole rosa" devi fare il bilanciamento del bianco.
2) raffeddata
Perché dovendo fare pose lunghe minuti l'elettronica si riscalda e introduce rumore.
Si raffredda la macchina montando sostanzialmente una peltier e un ventolino di dissipazione del calore. Si possono fare, senza sostenere "spese", come alternativa alla peltier i cosiddetti Dark, cioè foto con l'ottica chiusa al fine di "rilevare e quindi sottrarre" in sede di elaborazione il rumore.
Ti ringrazio x l'attenzione che hai dato alla mia foto,
Spero di essere stato abbastanza chiaro.
Un saluto
