I use an undriven DSLR on a standard camera tripod which can cost less than £100. I use the camera with a Canon 200mm lens attached. This means that you can do
satisfactory measurements down to magnitude 10. If I am doing an eclipsing binary series I will take 20 images at 4 secs per exposure. The images will be stacked using AIP4WIN and the stacked image analysed.
if the sets are ten minutes or fifteen minutes apart then the target system will still be in the field of view and can be quickly centred for each set.
