The 400D does, in fact, have ICNR. It's custom function 2 as Zuts said. That was a hard one to find, but I'm glad I did. I'll try that next time I'm out. Since I'm limited to 60sec. or less until I learn drift alignment or get into guiding, the extra exposure time shouldn't be a problem.
I still want to be able to do it manually however. I just like to know these things and want to get good at it.
The program I mentioned above that likes to mess with my computer will run better if it's the first program I use following a restart. I spent several hours last night experimenting with it (in between restarts
) and to my amateur eye seems to do a good job with multiple dark/light frames. It looks like that's the way I'm going to go.
Thank you all so much!
