Remark |
: |
A test shot to see how an unmodd DSLR w/o noise reduction could do the job in wide field at temperature below zero and with very low level of light pollution |
Comments after test :
This final image looks not too bad except lacking of H-alpha light in LMC.
Personally, I prefer wide field imaging with films, especially E200s.
Wish a modd DSLR could improve it, and maybe one day, I would remove the built-in IR blocking filter for grabbing more H-alpha light, if I kept using DSLR for deep sky imaging.
