Not sure. Gotta ask her again - probably a bad example to quote from anyway.
I'm not trying to prove any point. I'm just trying to find out if
a) it's normal to have this level of hot pixels with barely 14-minutes of exposure without LENR?
b) if it is, do they always have to use LENR for star trails - what if the exposure is 1 or 2 hours or more?
c) what are the alternatives (what PP steps?) to removing those hot pixels if say, battery runs out
Hope this is more articulate.
