The Canon 600D, 650D, 700D... all use the same sensor (reportedly) and are known quantities for astrophotography, but as such have been around a while and is old-tech compared to some other models on the market.
The 750D and 760D use a new 24MP sensor which is as yet unproven...or at least, I've not seen anyone posting images from one
Could be a great sensor, who knows
