Hehe:) its my second hobby (due to cloundy skies I guess it might be first:)

You are probably right. But I had this coupler already so used it:) also I will be using stellarmate and in Ekos they have linear focuser mode, so backlash wont be an issue ;)

Hey guys and girls, want to share my latest project - DIY focuser. It has custom PCB with TMC2130 motor controller. Motor itself is GM20BY with 1:250 gearbox. All in all it has 5000 steps per revolution which is more than enough for good focus on my setup (and probably many others Also I have designed custom holder to mount everything without brackets Ps. since focuser is programmable I can use whatever open source DIY focuser software I want, at this point I am using MyFocuserPro2.
