Cooling makes a big difference, and uncooled DSLRs cannot match a current generation cooled CMOS astro camera for low noise long subs, especially during summer nights. DSLRs generate internal heat from the processors and there is no way to get rid of it; the more subs you shoot the more the heat builds up. It won't affect the first sub but number one hundred will be a mess in comparison. Cooled cameras produce identical results all night long.
