Nikon D80 vs D3200 - Heat bloom on long exposures

[Helium_Junkie]

Does anyone know whether the D3200 is any better for sensor heat than the D80 on long exposures? Can't seem to find much info on this, would appreciate any help

Thanks!

Anywhere from 10 minutes and up during astrophotography or night time photography. The D80 gets massive purple blooms in the top corners.

Also, does anyone know if the D3200 can be computer controlled (or otherwise) to do time lapse photography?
