Along with the speed and decent aperture, another reason I went with the AG12 was its ability to provide quite wide field images (1.8deg X 1.8deg) but still in high enough resolution that it allows for very satisfactory narrow field images all at the same time

The Leaping Cheetah
So it provides lots of cool possibilities

It is also worth noting that the seeing was rather lack luster on both nights of data collection too, I hope to get to a site with good seeing at some stage.
