Description

Coal Sack Nebula.

500 2 second shots.

Raw files edited in Adobe Camera Raw to perform lens correction and fix vignetting then exported as TIF files.

I haven't had any success with DSS using Sony RAW files previously.

These TIF files seemed to have worked well, although the process took 36 hours on a pretty decent pc. This could be because they were 24bit.
