Dark and flat: checking live results during live stacking
Posted: Tue Mar 12, 2019 1:16 pm
Hi.
Because i'm having some problems about good results with dark and flat calibration during live stacking, i was thinking about a possible error i did during my last test.
While i was looking for a solution, i came accross this Robin's sentence "Once you have chosen your dark file it will be subtracted from each frame captured from then on (unless you set the subtract dark dropdown back to 'none')".
So, i explain my test.
I start live stacking. After some frames i add the dark frame: i wait one frame to see the live result. Then, i switched to "none" and wait one frame. Then i add the dark twice, to see the live result another time...And so on with flats, adding and remove them while the live stacking was going on...
So maybe that this cause the problems of poor results in dark and flats calibration during stacking? Changing continuously between adding dark and flat calibration to live stacking (and removing them, set back to 'none') could cause an error?
So if you start a live stacking session with dark calibration, for example, do you have to keep it unchanged? No possibility to add and remove flat or dark during live stacking session?
Thanks
