I have tried the workaround but unfortunately it does not seem to work. Voyager appears to call the platesolve2 (which is now actually ASTAP) but then it returns almost immediately and I do not see any evidence that ASTAP has actually been called.
It would be really nice if Voyager can support ASTAP directly. Platesolve2 is fast but fails about 50% of the time. ASPS will solve 100% of the time but is really slow. I am hoping that ASTAP will work better.
