Esprit 120 Focuser Mod

Post by skyhawk »

To image Ha indoors

Not being able to find a focuser I wanted for my Esprit 120, that came off instantly and went on instantly I decided to make one. I did not want one that was permanently engaged with the scope. Also I refuse to spend £200+

I bought another Skywatcher electronic focuser, a piece of 3mm alloy bar and a 2.5” by 6” round bar.

I won't go into detail as I have taken photographs, what amazed me was the final luck when I attached the vacuum cleaner drive belt it fitted 100% and I had NOT measured at any stage for it to.

The knob attached to the motor has TWO grub screw holes, 3mm which is why the other holes are offset.

I am NOT an engineer as you can see but have enjoyed this. Took a day

The good thing is that the whole unit can easily be swapped over to the other side of the scopes focuser

Looks good Jeremy. I've popped it in the mods section.

Can you put the belt on the fine focuser wheel, the reduced gearing might give you a bit more tweakability?

Hi Jeremy...

The belt drive mod looks great...a massive improvement in being able to focus if your hand isn't jiggling the scope!!!
