I'll expand that I prefer Stellarium's FoV display as it's easy to cycle through the 'scope / sensor combinations you might have, and the object images are generally more as you might image, rather than CduC's simpler graphics, it's also easier to check different dates / times for imaging. However for telescope control Cartes du Ciel has it, since I found Stellariumscope to be flakey at best. It might, *just* be OK with my HEQ5 but there's no way I'd trust it with my ASA mount, even if it could connect (I haven't tried it,and have no intention of trying).
Stellarium does, however have a much better night vision setting, as it turns the whole display red, whereas CduC leaves a lot of white around the edges. Better to use a red filter over the screen.
