So to get the same amount of intensity of colours if I shot green subs for 5 minutes then I should shoot red subs for 10 min and blue for like 11 min OR DO I JUST SHOOT THEM ALL AT THE SAME LENGTH???????
Thank you

Much better colour in the repro. Not sure which software you are using to colour combine, but my normal procedure in the past was to do the same length RGB and then use Excalibrator
http://bf-astro.com/eXcalibrator/excalibrator.htm to determine the colour ratios in CCDStack. Now I still take 1:1:1 ratios, but calibrate with PixInsight.
