GSO 305 mm - Canon T3 - 16 x 4 min (64 min) - ISO 800 - OAG - Coma Corrector
Two different process. With Tiff and CR2 files. I didn't see advantages in processing with Canon Camera RAW to TIF and stack with DSS.
note: I human, not machine. Therefore always will have some difference with two processing. So it is natural some difference between the two photos. ok?
