Autofocus setup using ZWO eaf & DSLR lens advice

Recommended Posts

Hello. As title, has anyone had any luck setting up the above? I have a Samsung 135mm which I’ll be using with my 1600mm and controlled by ASIair. If anyone’s found an off the shelf transmision/belt drive solution or gone through the pain of assembling one would you mind sharing the details at all? Thank you in advance.

Hello, thanks but I can’t search this on eBay - thinks I’m looking for a userid?

Ah ok, thank for that. I already have that setup but want to automate it. I'll be doing lrbg+narrowband and want to make it as precise as possible.

Thanks for that, it looks nice especially the mounting arrangement. I went for this setup; astrojolo supplied mounting rings and guidescope mount plus a toothed pulley/belt arrangement inspired by another user on here. I haven’t connected it all up to try it yet, I fear autofocus won’t work as I’m told there won’t be enough back focus  behind infinity to automate it but at least I should be able to control the motor focuser through asiair without touching it, which should still be more precise.
