Help to replace Takahashi focuser

[Miguel_EA1HTA]

Hi all !!

 

I'm planning to replace the Taka focuser by a FTF2025 with its adapter, but I have the following doubt: how can I disassemble the focuser housing from the Taka tube ?

 

On the FTF side (with adapter on) I can see the thread... but I'm not sure on how to remove the focuser from the tube: 

 

Should I try to turn the green housing, maybe with a strap wrench tool, or should I first unscrew a little bit the screw next to the housing, on the left?

To my understanding, the three tiny hex-screws are to work on focuser tightness, and are not related to focuser housing union to the tube...

 

But I'd like to confirm how to do it before crashing anything

 

 

Thank you in advance !!

Kind regards,

 

Miguel

None of the screws in your photos hold the focuser onto the white OTA.

The whole focuser will unscrew counter clockwise by hand.

On older Taks you may need to loosen a tiny grub screw that locks against the white tube first, newer Taks do not have the grub screw.

Take great care when screwing the feather touch on as the threads are quite fine.

Thank you very much for the fast answer, David.

It is new, so no grub screw.

I will apply a little more force with my hands then

 

 

Thank you !!
