Yes - just use a Bahtinov mask & watch in the downloaded shots
or do 2 second updates with binning.
It's much easier than live view on a DSLR.
If you have Maxim DL you can sample the stars in all 4 corners
plus the middle of each frame while you wait
for the next frame.
You can see FWHM in all 5 areas to compare with previous
frames to see if you're losing focus & what the seeing is like.
That sort of
real time update can save you a lot of wasted frames.
I remember once doing the LMC for over 3 hours without
realizing my focus was slightly off using a DSLR.
I only found out the next day when I went to process.
