Depends, however at 1200mm I am pretty sure that Astrotracer would not allow an exposure as long as 30 sec. The iOptron IEQ45 is a decent mass produced mount. Not in the same league as the high end mounts but you don't need that unless you want something that is totally invisible to your imaging (as in a robotic telescope under a roof or something to use in the field that is practically that way). As in $600 verses $6k. There are plenty of forums covering every type of mount, just make sure if you are looking to buy one you check out people who are using them the way you want to find out what quirks or adjustments they may need.
