I have a Takahashi FS-102 refractor and I want to automate the focusing process. It has a Cercis Astro focus motor system. I have been trying to autofocus through N.I.N.A. software routine with no success. I think the stock focuser is the problem, so I’m planning to change it to an Optec or a Feathertouch with motors.
Do I have to recollimate the system? Because it’s a refractor it is a little tricky to collimate (I think), so I must send it to TNR for service. I am out of USA.
What experiences have you had in this situation?
Thanks in advance for your answers.
