Stacking : Upper light threshold

#1

Post by Gwengwengwen »

Hello !
During stacking, there is an option with a light lower threshold avoiding stack of pictures if there is a cloud (for example). I haven't seen an upper threshold avoiding stack of pictures when the neighbour’s automatic light turns on (too much light). It exists ? If not, should be possible to add it ?
Thanks a lot !

Hi,

the brightness threshold is measuring the brightness of stars against the background around them, so if think cloud appears the brightness measured should decrease (the cloud will be blocking some of the starlight). This is improved in version 4.2 (currently in beta testing) where the stars are tracked individually from frame to frame during a live stack to make sure that the measurements of star brightness are properly comparable from one frame to the next.

Hope this helps,

Robin
