Hi all
I'm using Nebulosity2 and the manual advises that when creating a master bad pixel file you should "combine several frames taken at the longest exposure duration you expect to use".

This all makes sense, but what iso setting should i use? Do the RAW bad pixel frames need to have matching iso settings of the light frames?

Plus supplimentary question:
If i create a library of bad pixel masters for how long can they be used, ie
best before date!

It appears that one of the benefits of bad pixel mapping is that you don't have to spend extra time after each session shooting dark frames.

Regards
Carl
