well I was looking at about $1000 for the focuser, about $600 (prob Canon 300) for the camera..about $4-500 on good RGBL + auto changer
but a really good corrected refractor is going to be about $5-6K.. and that will take a while to save up for.. so I figured spend $900 on a 150mm skywatcher and the laptop can auto re-focus between shots...
infact I plan on using the toucam as an autotracker.. I plan on setting the scope up and letting it go.. it's too damn cold in winter in Canberra
