Interesting new hardware perspective: reduce the required exposure time instead of perfecting the tracking?
And the box out of which we think gets smaller and smaller:
The Polarie, my Samyang 500mm 6.3, the ZWO CMOS ASI1600MM-Cool cam, 2 ballheads and a tripod = 4.5kg -
and *coughs* a recording laptop with multiple fast processors and fibre optic SAN access.
The SAN can help with reducing heating cost during winter
