Stacking multiple live stacks in DSS
Posted: Mon Jun 12, 2017 7:51 am
Hi there, just a question of correct methodology really.
Say i capture a live stack of a target the first night of say 1000 frames. Then i do the same the second night and get 700 frames, third night 1500 frames etc... If i choose to save individual frames, then obviously i can load them all up in DSS and do a stack that way, but that means id have folders with HUGE sizes in my hard drive.
Therefore, say I wanted to stack the 3 final saved images in DSS. Would each individual stack need to have the same amount of frames in it i.e. all of them should be 1000 frames, for the SNR of each stack to be the same, or does it not really matter if the stacks from different nights contain a different number in them. I ask this because i might not be able to achieve the same number of frames in a live stack in during different nights. I'm also not 100% understanding the stacking process in DSS to know if this would be an issue or not.
Thanks for the help.
