Hi Duncan
The camera is but one part of the astrophotographer’s system. The mount is arguably the most important part for long exposure deep sky photography where most people use auto guiding, usually through an off axis guider plus auto guider, or a separate guide scope with an auto guider.
Several people on the Forum started lunar and planetary imaging with the lowly ToUcam and a manual dobsonian, but I think they soon found the limitations of their set up and moved onto equatorial mounts.
Wide field astrophotography with a short focal length refractor is relatively forgiving for exposures up to around 30 seconds, once you are polar aligned.
Cheers
Dennis
