Hi Alex,
I'm not sure of the limits of Deep Sky Stacker, but certainly can imagine it would be CPU and Memory related. Also one point there's no need to limit to 5 sec exposures, go crazy do 10, 20 , 30 heck 60 seconds whatever, as long as you don't over expose the image. That way you'll have fewer images to stack for the same/similar image depth/noise. Sounds like you're in for a lot of fun with your new gear and dark skies.
Best
JA
