Not sure is this is the right place but I'll ask. I have a Celestron Edge, but trying to image at F-10 is little advanced for me still. I currently have a feathertouch crayford attached to the back, but that prevents me from adding an OPTEC focal reducer. I'm curious if anyone has been successful using ACP and a feathertouch replacement focuser for the Celestron mirror shift focus knob? Does this cause havoc with pinpoint, guider problems, or is ACP able to overcome the mirror flop issues by frequent auto focusing? My other option is to consider an Astrotech 8" RC which I could switch the crayford. When I win the lottery, I'll get a 6 in refractor but in the meantime....
