@greatgodoffire @jdlbt I think you are mixing "autoguiding" with "tracking". Tracking is the basic "turns with the Earth's rotation" that any electronic mount can do. "Autoguiding" is precision tracking at a arcsecond/few pixel level to account for mount imperfections. No £600 mount+scope will do that. At best you'll be able to take 15s images before they trail. With the high F-ratio of a Mak, that's not much light.
