Dear @Tech@ZWO , there is about 20 feedbacks on this particular feature ; which you should pay attention to. Indeed, the person that are requesting this feature are likely people who have a level of mount that enable it, meaning that they are ready to spend a important amount in astrophotography. Now, with such investiment you expect good results, which PEC enable. Right now the only way to take this step further is to move away from Asiair like I am considering right now, only for this reason (and overall, have more flexibility over guiding settings). The same people that spending this amount on mount will be the same spending on Camera, filter wheel, etc... which will have no reason to buy ZWO anymore.
I think this is a mistake from a strategy point of view to adress only "casual" astrophotographer, people with low end mount or DSLR, when they will evolve in material they will expect more from the software at the same time they will be ready to spend more money into the hobby.
Seriously, I love the Asiair but the guiding is so poor that I am considering moving away when I also looking at camera, filter wheel etc.. at the same time. Too bad.
