Hi all, The autoguiding battle continues... It seems that the QHY-5 runs out of back focus, how much back focus? im guessing 1 extra inch!
Has anyone else experienced this using a OAG?
my question is, Should i source a longer nose tube for the QHY-5, or should I get a tube extender?, or should i purchase a Celestron T adapter which looks to be 20mm longer than the bintel one i am currently using?.

My thoughts are (please correct me if im wrong) but adding a longer T adapter to my imaging train, will decrease the back focus required to bring the QHY-5 into focus?
Thanks all
