G'Day Mario,
Yep, I have the ToUcam, and for me I think it's the way to go. Eventually I would like to get into the deep sky stuff which really means a dSLR or a dedicated astro camera, but in the meantime there are lots of lessons to be learnt!
So I find I have plenty of challenges and things to learn with the little ToUcam, for not much capital outlay. It is great for planetary and lunar stuff, and with the long exposure mod it can be pushed into some deep sky stuff and used as a guide camera for when you eventually get a dSLR or astrocamera.
Yes, it has it's limitations, but I can't complain given the meagre price!
I haven't out grown it yet. (And I doubt I will until I can move to a place where I can set up my scope permanently).
I think a ToUcam is a great way to get into astro photography!
Al.
