If you want a good uncooled camera for hiking in dark skies a modified DSLR would be your best choice. It does not require anything else to run, no computer, power supplies etc. Just an intervalometer (plenty of them on Ebay). A Vixen Polarie is smaller than most cameras and that is your tracking mount.
You can't beat a modified DSLR unless you go to more expensive astro cameras and they are no longer hiking portable.
An astro CCD needs a power supply, computer to run. A lot to carry if hiking.
It also needs a mount.
