Hi - maybe this is the forum I've been looking for? The project I'm working on is designed to get some old technology that requires continual human intervention to function automatically.
I have a 10 year old Takahashi Equatorial mount that I use for astrophotography - long exposures (5 - 10 minutes) over many hours. The mount also has a +ve earth! It comes equipped with a hand controller to slew the RA axis and DEC axis, which are perpendicular. The idea is, that both axis are slewed a small amount between exposures. That way, different pixels are exposed by the image, instead of stacking pixel on pixel with the same photons. This helps to reduce noise and other undesirable artifacts. The problem, is the need to be always in attendance.
I've made a smaller stepper driven device (robot) to push the hand controller buttons. This needs to happen between exposures, but I've run into some interesting timing issues that I have not yet resolved. I'll post the details in the appropriate sub forum.
Hope to find some answers and learn more about Arduino controlled photographic projects.
