Stacking in Nebulosity
Folks,
I've stacked same exposure lengths with Nebulosity with really good success and just about ditched DSS and photoshop for the time being.
Took to the skies last night and captured various length exposures of NGC5139. eg 20secs, 40secs, 60secs and 120secs, as much as I could before the clouds rolled in.
To stack and process them in Nebulosity I cannot just dump them all into the mix and hope all is well at the end?
Do I need to stack them in groups of the same exposures and then stack them again at the end to get the final image then process?
Many thanks
Paul
