Well I'm hoping the FL of the main scope which is 1500mm (945mm with a .63 F/R) isn't going to really be a factor as the guide scope should be backup...if I get my drift alignment spot on my subs probably will be in the 2 to 5 min range so the guider will be there as a "just in case"...I'm a newbie to AP so I will keep the subs short until I get it perfected...
Rob...the nose on the webcam itself adds 1" so just removing the locking ring behind the objective lense still wouldn't be enough...it needs about 1 3/8" removed from the tube to make it work...
