Is it possible for me to write the output file to an external drive

Yes, but make yourself sure first that the interface, filesystem, etc
is reliable enough for a logfile. Others have discovered the hard way
how bad is to write the logfile to an unreliable place

Ah, the simple joys of being held up as an example of what not to do ;-).
Yes, having learnt the hard way, I'd suggest that you not write to a
network file system and particularly not an CIFS/SMB filesystem. I have
no experience with using NFS for log files, but based on past experience
I wouldn't go there.
Practically, what this means, is that if you are using ddrescue from a
live CD (as I was) you need a known good drive to store the log file to
in addition to the drive you are copying the restored data to. A USB
stick may be suitable, though I haven't tried.
