I actually never thought it would be possible to measure the movement with amateur equipment - I was wrong. I wouldn't bother using drift scans for "pretty" pictures - long exposures are best for these. |
I have used my camera to take photos of proxima centaurus over the last 7 years using just 20 sec exposures (not drift scan) and have plotted the propper motion and some parallax shift. This is using very amateur equipment in my backyard. It is certainly possible.
My CCD camera is a home built one using a KAF0401E chip (NABG). I have borrowed our clubs old sbig ST7 with ABG version of the same chip. It is nowhere near as sensitive as my camera. I didn't realise that htere would be much difference but there is.
I have attached a plot of the movement.
