Description

Also this year, here's the M42, the great Orion Nebula! After newton 200/1000 and 70/420, this is the time for 80/480 to collects photons :) Are 24x300 sec at ISO 800 with Canon 450D modified. It is a HDR composition with shots from 5-30-300 sec, for increasing the dynamics and therefore do not saturate the core. External clouds are pretty noisy, but with 2 hours I couldn't expect miracles :)

Anche quest'anno ecco M42, la grande nebulosa di Orione! Dopo il newton 200/1000 e il rifrattore 70/420, questa volta è toccato all'80/480 il compito di raccogliere i fotoni :) Sono 24x300 sec a 800 ISO con Canon 450D modificata. E' una composizione HDR con scatti da 5-30-300 sec, in modo da aumentare la dinamica e quindi non saturare il nucleo. Le nubi esterne sono abbastanza rumorose, ma da 2 ore non potevo aspettarmi miracoli :)
