hi Robin
how did you get that rates need to be higher? was the line not long enough?
12sec per deg is about 10x sidereal and for a 5 min exposure, might ovetshoot the fov. not that it matters. I guess pixel scale is also a factor, I didn't think of that.
have you tried this, in a real test, stop your tracking for 1min while exposing and see what the length is.
can I suggest, having two modes, one for eqascom where rate is 2xsidereal or maybe a choice between 2 4 and 8x. and a gemini mode with the centering speed you mentioned.
I still think going west for 30s at 2x and turning tracking off for 30 would get it to the same start point, you could easily do this with the eqascom buttons.
will be interesting to see your result when you did this.
btw congrats on the straight line.. its the 4 or 5min exposure that confirms your PA.
cheers
