I am using iOptron cem 25p mount with canon 5D mk II and tamron 150-600mm. I use Backyard EOS, Stellarium and Astro tortilla in an attempt tp platesolve. Astrotortilla takes a picture but then reports unable to solve 0.0s. I believe this means it was unable to platesolve within 0.0 seconds. I have no idea what setting would give AT more time in which to complete a solution. My online searches provide no help.
