Ammasso globulare in Ercole (M13) senza troppe pretese :) Attraverso la tecnica dell'HDR è stato possibile desaturare il nucleo, in modo da non avere zone bruciate. Infatti sono stati fatti 3x120 sec per il nucleo e 18x420 sec per il segnale debole delle stelle esterne. Ho usato il Tecnosky 80/480, quindi ho preferito croppare l'immagine per far risultare meglio l'ammasso :) Canon 450D modificata.


Globular cluster in Hercules (M13) with the HDR technique :) I have taken 3x120 sec for the core and 18x420 sec for the weak signal of the external stars. I used the Tecnosky 80/480, so I preferred to crop the image to see better this DSO:) Canon 450D modified.
